|Transitivity and valency|
|Reflexives and reciprocals|
In linguistics, a causative (abbreviated CAUS) is a valency-increasing operation that indicates that a subject either causes someone or something else to do or be something or causes a change in state of a non-volitional event. Normally, it brings in a new argument (the causer), A, into a transitive clause, with the original subject S becoming the object O.
All languages have ways to express causation but differ in the means. Most, if not all, languages have specific or lexical causative forms (such as English rise -> raise, lie -> lay, sit -> set). Some languages also have morphological devices (such as inflection) that change verbs into their causative forms or change adjectives into verbs of becoming. Other languages employ periphrasis, with control verbs, idiomatic expressions or auxiliary verbs. There tends to be a link between how "compact" a causative device is and its semantic meaning.
The normal English causative verb or control verb used in periphrasis is make rather than cause. Linguistic terms are traditionally given names with a Romance root, which has led some to believe that cause is more prototypical. While cause is a causative, it carries some additional meaning (it implies direct causation) and is less common than make. Also, while most other English causative verbs require a to complement clause (as in My mom caused me to eat broccoli"), make does not require one ("My mom made me eat broccoli"), at least when it is not being used in the passive voice.:36-7
Many authors have written extensively on causative constructions and have used a variety of terms, often to talk about the same things.
S, A, and O are terms used in morphosyntactic alignment to describe arguments in a sentence. The subject of an intransitive verb is S, the agent of a transitive verb is A, and the object of a transitive is O. These terms are technically not abbreviations (anymore) for "subject", "agent", and "object", though they can usually be thought of that way. P is often used instead of O in many works.
The term underlying is used to describe sentences, phrases, or words that correspond to their causative versions. Often, this underlying sentence may not be explicitly stated. For example, for the sentence "'John made Bill drive the truck'", the underlying sentence would be Bill drove the truck. This has also been called the base situation.
A derived sentence would be the causativized variant of the underlying sentence.
The causer is the new argument in a causative expression that causes the action to be done. The causer is the new argument brought into a derived sentence. In the example sentence above, John is the causer.
The causee is the argument that actually does the action in a causativized sentence. It is usually present in both the underlying and derived sentences. Bill is the causee in the above example.
There are various ways of encoding causation, which form somewhat of a continuum of "compactness.":74-5
Lexical causatives are common in the world's languages. There are three kinds of lexical causatives, the unifying factor being that the idea of causation is part of the semantics of the verb itself.:177 (English, for example, employs all three of these kinds of lexical causatives.)
On the surface, lexical causatives look essentially the same as a regular transitive verb. There are a few reasons why this is not true. The first is that transitive verbs generally do not have an intransitive counterpart but lexical causatives do. The semantics of the verbs show the difference as well. A regular transitive verb implies a single event while a lexical causative implies a realization of an event::511
Sentence (b) is judged ungrammatical because it goes against the successful event implied by the verb melt.
These are split into two varieties: agentive and patientive ambitransitives. Agentive ambitransitives (also called S=A ambitransitives) include verbs such as walk and knit because the S of the intransitive corresponds to the A of the transitive. For example:
This type of ambitransitive does not show a causative relationship.
For patientive ambitransitives (also called S=O ambitransitives), such as trip and spill, the S of the intransitive corresponds to the O of the transitive:
These are further divided into two more types, based on speakers' intuition. Some, like spill in (2), are primarily transitive and secondarily intransitive. Other verbs like this include smash and extend. Other verbs, such as trip in (3) go the other way: they are primarily intransitive and secondarily transitive.
Other examples of this type include explode, melt, dissolve, walk, and march. It is this type of ambitransitive verb that is considered a causative:38 This is given some anecdotal evidence in that to translate (3b) above into languages with morphological causatives, a morpheme would need to be attached to the verb.
Lexical causatives are apparently constrained to involving only one agentive argument. Semantically, the causer is usually marked as the patient. In fact, it's unlikely whether any language has a lexical causative for verbs such as "swim," "sing," "read," or "kick.":3
English fell (as in "Paul felled the tree") can be thought of as a lexical causative of fall ("the tree fell"), exemplifying this category.:177 This is considered a lexical change because it is not at all productive. If it were productive, it would be an internal change morphological causative (below).:
English has verb pairs such as rise and raise, eat and feed, see and show where one is essentially the causative correspondent of the other.:177
These pairs are linked semantically by various means, usually involving translation. For example, burn, as in The grass burned (intransitive ), would translate as awa- in Yimas while burn, as in I burned the grass (transitive), would translate as ampu- in Yimas:40
There are eight different morphological processes by which a causative may be marked, roughly organized by compactness::34
|Process||Basic Verb||Causative Form||Language|
|internal change||tìkti 'be suitable'||táikyti 'make suitable'||Lithuanian|
|tone change||n (high falling) 'be awake'||n (low level) 'awaken, rouse'||Lahu|
|consonant repetition||xarab 'go bad'||xarrab 'make go bad, ruin'||Gulf Arabic|
|vowel lengthening||mar 'die'||ma:r 'kill'||Kashmiri|
|reduplication||bengok 'shout'||be-bengok 'make shout'||Javanese|
|prefix||g?bba 'enter'||a-g?bba 'insert'||Amharic|
|suffix||-kam- 'die'||-kam-isa- 'kill'||K'iche'|
|circumfix||-?'am- 'eat'||-a-?'m-ev- 'feed (make eat)'||Georgian|
Within morphological causatives, this degree of compactness bears an important variable when considering the semantics of the two processes. For example, mechanisms that do not change the length of the word (internal change, tone change) are shorter than those that lengthen it. Of those that lengthen it, shorter changes are more compact than longer.
Verbs can be classified into four categories, according to how susceptible they are to morphological causativization::4-11
This hierarchy has some exceptions, but it does generally hold true. For example, given a text of Guarani, only about 16% of causatives apply to transitives.:5 For some languages, it may not apply to transitive verbs productively and may only apply to verbs that denote abstract action or consumption of food. Additionally, within Athabaskan family, all languages can causativize inactive intransitives, but not all of them can causativize active intransitives or even transitives.:5
A number of languages involve a form of analytic causative that involves two verbs in a single predicate, such as French, Spanish, Italian and Catalan.:35 For example, when French faire is used as a causative, the causee noun phrase cannot occur between it and the next verb.
|"I will make Jean eat the cakes.":35|
|"Go ahead and run it [the tape recorder]!" (lit. "make it start off")|
Some languages use a periphrastic (or analytic) construction to express causation and typically include two verbs and two clauses. English causatives prototypically use make (but other verbs such as cause, order, allow, force, compel can be used) in the main clause with the lexical verb in a subordinate clause, as in "I made him go.":35-7
|"Satan unsuccessfully tried to make Jesus do bad."|
Canela-Krahô has a combination of the two in which the causee is marked twice, once in each clause:
|"Capi made me sleep."|
Portuguese also has a periphrastic construction like that of English but unlike most other Romance languages:
|"I made José eat the cakes."|
Analytic causatives are sometimes not considered to be valency increasing devices, but they can semantically be interpreted as such.:181
A language may have one or more different formal mechanisms for expression causation. For languages with only one, the semantic range is broad. For those with multiple, there is always a semantic difference between the two.:61 R.M.W. Dixon breaks down these semantic differences into 9 parameters, involving the verb itself, the causee, and the causer::62-73
These parameters are not mutually exclusive. Many causative constructions involve the semantics of two or more parameters. However, the difference between the causatives in a language most likely will be distinguished by one of the parameters.
There is a strong correlation between the semantics of a causative and the mechanism by which it is expressed. Generally, if a causative is more "compact" than another, it usually implies a more direct causation.
For animate and conscious objects, there is a different difference in meaning:
(1) only makes sense if they are animate and awake. Barring magic, (2) only makes sense if the object is inanimate or unconscious.:784
Generally, the more distance between the causer and the causee, the more finite the verb. Consider the following examples from Spanish:
|"Montezuma made Cortés eat bread."|
The first example implies that Montezuma was physically there and was directly involved in making Cortés eat bread. The second example implies that Montezuma was not physically there and arranged for something to happen to make Cortés eat bread, perhaps by killing all of his cattle. That could approximate the English construction "Montezuma got Cortés to eat bread." Therefore, at least in Spanish, a conjugated verb implies a more direct causation.:185
Dixon examines this correlation cross-linguistically, and summarizes his findings in the following table.:76 In this table, L refers to lexical causatives, M1 refers to more compact morphological processes while M2 refers to less compact processes, CP refers to complex predicates (two verbs, one predicate), and P refers to periphrastic constructions. These processes are explained more clearly in the devices section above.
|Causative type 1||Causative type 2||Causative type 1||Causative type 2|
|M||P||Bahasa Indonesian, Malay|
|2||intransitive||all transitive||M||P||Austronesian languages, Mayan languages, etc.|
|intransitive and simple transitive||ditransitive||M||P||Basque, Abkhaz|
|3||causee lacking control||causee having control||L||M||Japanese|
|4||causee willing||causee unwilling||M1||M2||Swahili|
|5||causee partially affected||causee fully affected||M1||M2||Tariana|
|6||direct||indirect||M1||M2||Nivkh, Apalaí, Hindi, Jingpaw|
|M||P||Buru, Chrau, Alamblak, Mixtec, Korean|
|P||M plus P||Chrau|
Parameter 9, Involvement, cannot be included in the table because the only two languages with this distinction, Nomatsiguenga and Kamayurá, the morphemes are about the same length.:75 When a larger sample of languages show this distinction, perhaps this parameter can be included in the table.
The table shows that for each of eight semantic parameters outlined in the semantics section above, more compact causative processes show one distinction while less compact processes show the other distinction. For example, Parameter 6 distinguishes between more direct and less direct causation. In Hindi, M1, or the shorter morphological process, shows direct causation while M2, the longer morphological process, shows indirect causation.
Summarizing the table, Dixon has given two prototypes for causatives::77
All eight of the components in each prototype are never attested in a single causative. However, a single process may have two or three components. Dixon admits to these being very tentative and in need for further investigation.:77-8
R.M.W. Dixon also outlines the syntactic possibilities of causatives in the world's languages.
Since intransitive verbs have low valency, virtually any type of causative construction can apply to them productively within a language. Some constructions are only allowed with intransitive verbs and some languages (such as Arabic, Blackfoot, and Gothic) only allow causatives of intransitive verbs, with some exceptions.:5 In all cases, the original subject of the underlying intransitive verb corresponds with the object of the derived transitive verb. All languages have this construction, though some allow a semantic difference if the original subject is marked differently (such as Japanese and Hungarian).:45
In the causative of a transitive verb, the new causer always becomes the new A of the sentence. What happens to the causee and the original object depend on the language. Dixon shows that there are five main types of situations:
|type||causer||original A (causee)||original O||languages|
|(i)||A||special marking||O||Nivkh, Telugu|
|(ii)||A||retains A-marking||O||Kabardian, Trumai, Qiang|
|(iii)||A||has O-marking||has O-marking||Hebrew, Tariana, Amharic, Sanskrit:180|
|(iv)||A||O||non-core||Javanese, Swahili, Kammu, Babungo|
Within type (v) there are two main subtypes. Either the original A goes into the first empty slot in a hierarchy or it always takes a certain function.:54
For the first subtype, there is a hierarchy involved in the language:
French is a language that follows this hierarchy. When a causative is employed, the original A does not get marked the same for intransitives, transitives, and ditransitives.:54 In this first example, the verb in intransitive, and with the subject slot taken, the original A becomes a direct object:
|"I will make Jean run."|
The following example has a transitive verb. The subject and direct object slots are filled (with je and les gâteaux, respectively) so the original A becomes an indirect object:
|"I will make Jean eat the cakes."|
This final French example has a ditransitive verb. The subject is je, the direct object is une lettre, and the indirect object is directeur, so the original A is marked as an oblique:
|"I will make Jean write a letter to the headmaster"|
Most other languages are of the second subtype of type (v), and the original A takes on a set case or marking, regardless whether the underlying verb is intransitive or transitive:
|causer||original A (causee)||original O||languages|
|A||dative||O||Sanuma, Apalai, Kamaiurá, Turkish, Japanese|
|A||instrumental||O||Hungarian, Kannada, Marathi|
|A||locative||O||Some languages of Daghestan|
|A||allative||O||West Greenlandic Eskimo|
|A||adessive||O||The morphological causative in Finnish.|
The syntactic and morphological constraints of individual language generally restrict causatives of ditransitive verbs. The underlying phrase already contains an A, O, and indirect object, and so in order to accommodate a fourth argument, languages employ a variety of constructions. They tend to be idiosyncratic and are difficult to group together into types. Additionally, data is patchy for many languages since descriptions of languages seldom include information of causatives of ditransitives.:56-9
Some types of causative constructions essentially do not permit double causatives, e.g. it would be difficult to find a lexical double causative. Periphrastic causatives however, have the potential to always be applied iteratively (Mom made Dad make my brother make his friends leave the house.).
Many Indo-Aryan languages (such as Hindustani) have lexical double causatives.
For morphological causatives, some languages do not allow single morpheme to be applied twice on a single verb (Jarawara) while others do (Capanawa, Hungarian, Turkish, Kabardian, Karbi), though sometimes with an idiomatic meaning (Swahili's means force to do and Oromo's carries an intensive meaning). Other languages, such as Nivkh, have two different morphological mechanisms that can apply to a single verb. Still others have one morpheme that applies to intransitives and another to transitives (Apalai, Guarani). All of these examples apply to underlying intransitive verbs, yielding a ditransitive verb. So far, there are no reliable data for a morphological double causative of a transitive verb, resulting in a verb with four arguments.:59-61
Yokuts, an indigenous language spoken in California, has a morpheme, -lsa?, that indicates causation in addition to repetition. This is separate from the language's normal mechanisms of causation.
|"one who makes (people) play music repeatedly"|
This implies a single act by the causer, but multiple acts by the causee.
The causative voice is a grammatical voice promoting the oblique argument of a transitive verb to an actor argument. When the causative voice is applied to a verb, its valency increases by one. If, after the application of the grammatical voice, there are two actor arguments, one of them is obligatorily demoted to an oblique argument.
|"Children read books."|
|"(They) make children read books."|
The causal or causative case (abbreviated CAUS) is a grammatical case that indicates that the marked noun is the cause or reason for something. It is found in the Dravidian languages Kannada and Telugu, the Native South American language Quechua, and Northeast Caucasian Archi. It is also found in extinct Tocharian B, an Indo-European language.
The causal-final is a grammatical case in Hungarian (and Chuvash) expressing the meaning 'for the purpose of, for the reason that',:93 and denoting price asked of or paid for goods.:116 It is formed by adding the ending suffix -ért to the end of the noun, e.g. kenyér "bread" >kenyérért "for bread", e.g. elküldtem a boltba kenyérért "I sent him to the store for bread".:115 It is not affected by vowel harmony in Hungarian.:111
Shibatani lists three criteria for entities and relations that must be encoded in linguistic expressions of causation:
This set of definitional prerequisites allows for a broad set of types of relationships based, at least, on the lexical verb, the semantics of the causer, the semantics of the causee and the semantics of the construction explicitly encoding the causal relationship. Many analysts (Comrie (1981), Song (1996), Dixon (2000) and others) have worked to tease apart what factors (semantic or otherwise) account for the distribution of causative constructions, as well as to document what patterns actually occur cross-linguistically.
Bernard Comrie focuses on the typology of the syntax and semantics of causative constructions proper. Crucially, Comrie (and others to be discussed here) distinguish between the linguistic encoding of causal relations and other extra-linguistic concerns such as the nature of causation itself and questions of how humans perceive of causal relations. While certainly not irrelevant, these extra-linguistic questions will, for now, be left aside. Comrie usefully characterizes causative events in terms of two (or more) microevents perceived of composing a macroevent, and encoded in a single expression (of varying size and form). Formally, he categorizes causatives into 3 types, depending on the contiguity of the material encoding the causing event and that encoding the caused event. These are: 1) lexical causatives, in which the two events are expressed in a single lexical item, as in the well-discussed case of English kill; 2) morphological causatives, in which the causing event and the caused event are encoded in a single verbal complex via causative morphology, and, prototypically, morphological marking showing the status of affected arguments. Finally, Comrie discusses analytic causatives, in which the causing event and the caused event are encoded in separate clauses.
Comrie's work is also noteworthy for having brought the notion of syntactic hierarchy to bear on the typology of causative constructions. A hierarchy of grammatical relations had already been formulated to help explain possibilities for relative clause formation (first presented as Keenan and Comrie's (1972) NP accessibility hierarchy; see Croft 1990: 147), and Comrie argued that a similar hierarchy was in play, at least in some constructions, in the marking of the original A argument when a base transitive clause is causativized. The hierarchy is as follows:
Comrie's argument was, in short, that some causativized-transitive constructions mark the new A as belonging to the leftmost available slot in the above hierarchy. Dixon (2000) fleshes out a version this analysis in more detail.
Presenting a typology of causatives and causation based on a database of 600 languages, Song is very critical of typological work that depends on statistical inference, citing data from the Niger-Congo family that contradicts some earlier claims that "languages within genera are generally fairly similar typologically". Song therefore culls data from every language for which adequate documentation is available to him, and categorizes the various causative constructions gleaned therefrom into three classes: COMPACT, AND and PURP.
Song employs the following terminology:
The major differences between Song's analysis and Comrie (1981) and Dixon (2000), is that Song lumps the range of lexical and morphological causatives together under the label COMPACT,:20 in which [Vcause] can be "less than a free morpheme" (e.g., bound morpheme [prefix, suffix, infix, circumfix, reduplication], zero-derivation, suppletion); or "a free morpheme",:28 in which [Vcause] and [Veffect] form a single grammatical unit. Most of the examples given look like serial verb constructions, and no in-depth analysis is undertaken for some of the constructions in which [Vcause] and [Veffect] are less formally contiguous. Song notes this non-contiguity, but does not undertake to explain why it might be important.
The AND causative, for Song, is any construction with a separate [Scause] and [Seffect] i.e., in which "two clauses [are] involved".:35 This, in theory, could include larger, multi-clausal expressions of causal relations which many analysts probably would not label a 'causative construction', e.g.: 'It rained yesterday, so they stayed home', but the boundaries of the AND causative category are not discussed.
One of Song's major contributions to the literature[according to whom?] is fleshing out an analysis of his PURP causative. These are constructions which encode intended causation on the part of the causer, but which do not encode any outcome: i.e., the speaker encodes [Vcause] and causer intentionality, but remains agnostic as to whether [Veffect] was felicitously effected.
Leonard Talmy conducts an in-depth investigation of different types of causal relations. Talmy refers to these as "lexicalization patterns," a term which remains unclear to me[who?], given that few of the examples given in his discussion are lexical items, and most interpretations of "different types of causation incorporated in the verb root" are in fact wholly dependent on other morphosyntactic material in the clause. Let us[who?] first examine his list of possible (semantic) causative types,:69-70 with examples:
One question remaining to be explored is how this set of divisions usefully differs from other analysts' typologies of the semantics of encoding causal relations. Some overlap in the types of semantic information in play is immediately apparent, however: in cases of instrument causation ('the hammer broke the cup'), we would certainly expect the 'causer' to be acting directly [Dixon's criterion 6] and to be involved in the activity [criterion 9]; likewise, we would expect instances of caused agency to include more information on causee control on willingness [criteria 3 & 4].
In Proto-Germanic, the parent language of Germanic languages such as English, causative verbs are formed by adding a suffix -j/ij- to the past-tense ablaut of a strong verb, with Verner's Law voicing applied. (All of those characteristics derive from the way that causative verbs are formed in Proto-Indo-European, with an accented -éy- suffix added to the o-grade of a non-derived verb.) Here are some examples:
In English, to sit/to seat", and in German, sitzen/setzen form pairs of causatives/resultatives.
Additionally, there are several morphemes that can express causation. For example, -(i)fy can be thought of as a causative in that it is a derivation that turns an adjective or noun into a "verb of becoming":
en- can also be a causative. In English, adjectives (or stative verbs in other languages) can express the acquisition of a quality or changes of state with causatives, in the same way as with regular verbs. For example, if there is a stative verb to be large, the causative will mean to enlarge, to make grow. The reflexive form of the causative can then be used to mean to enlarge oneself, or even as a middle voice, to grow.
As far as lexical causatives are concerned, English has at least 49 causative verbs. Roughly half affect only sentient beings: allow, block, cause, enable, force, get, help, hinder, hold, impede, keep, leave, let, make, permit, prevent, protect, restrain, save, set, start, stimulate, stop. The others can affect either sentient or non-sentient beings: aid, bar, bribe, compel, constrain, convince, deter, discourage, dissuade, drive, have, hamper, impel, incite, induce, influence, inspire, lead, move, persuade, prompt, push, restrict, rouse, send, spur.
In Sanskrit, there is a causative form of the verb (?ijanta), which is used when the subject of a clause forces or makes the object perform an action. The causative suffix -ay is attached to the verbal root, which may cause vowel sandhi to take place:
In Persian, the causative form of the verb is formed by adding ân(i)dan to the present stem:
The Causative verbs are called projojôk kriy? (? ?) in Bengali. In the simplest way, the causative form of a verb can be formed by adding the suffix "-no" with the verbal noun form of the given verb.
From the Verbal Root (dh?tu ? in Bengali) perspective, the formation of causatives is done by adding the suffix "-?" -? with the verb roots ending with a consonant, and the suffix "-o?" ? with those roots ending with a vowel. Thus, the Verbal root transformations of the two previously mentioned verbs are:
These verb roots are thereafter inflected with tense, aspect and mood.
In most Semitic languages, there is a causative form of the verb. It is postulated that in Proto-Semitic, the causative verbal stem was formed by the ?- prefix, which has become ?a-, hi- or ?- in different languages.
Japanese has a morphological device to signify causation. Many verbs undergo internal change in various semiregular patterns between intransitive forms and causative transitive forms:
In the context of an intransitive verb, the syntax of Japanese causatives allows a two-way distinction in the causee's willingness to perform the action. If the new object is marked in the accusative case (o), it suggests that the causee did the action willingly, suggesting the agent allowed or requested the action rather than forcing or demanding it. However, if the object is marked in the dative case (ni), it expresses the idea that the causee was forced to perform the action. (This is not possible with a transitive verb as a clause cannot contain two noun phrases marked as accusative.):45, 65-66
Khmer has six prefixes and one infix to derive the causative form of verbs, but they vary in frequency and productiveness. The consonantal prefix p- is one of them:
The causative suffix is often used irregularly and/or because of historical reasons, as the following Finnish examples:
Hungarian marks the original subject of an intransitive differently in causative forms to convey direct causation. If the causee is marked by the accusative case, a more direct causation is implied than if the instrumental case is used.:45-6
In Malay/Indonesian, causatives are formed from the prefix per- (it becomes memper- after actor focus/active prefix meng-). While most languages uses their causative affix for derivational purposes, it has integrated to Malay verb inflection system.
The -uka suffix (or one of its allomorphes: -yka, -ka) is added to transitive verbs:
The guero- (rero- or just ro-) prefix can also be added to intransitive verbs. It has a comitative meaning and translates roughly as "to cause something or someone to participate in an action with the subject:"
The same root (guata) can take both causatives but with different meanings.
Causativity is often used in honorific speech in Classical Nahuatl, and rather than simply "doing," the honored person "causes himself to do."
The semantic factor of causee control, or the degree of control that that causee wields over the effecting of the caused microevent (also discussed as parameter #3 on Dixon's (2000:62) list) and which Rice (2001) finds to be a major factor in other Athabaskan causatives helps account for much of the distribution of the Hupa syntactic causative (below).
Golla, in his (1970) descriptive grammar of Hupa (summarized in Sapir and Golla (2001)), describes three classes of morphologically-derived causatives:
# causatives from descriptive neuters with ?-classifier (176)
ni-whon' 'be good, beautiful' -> O ni-(w)-?-whon' 'cause O to be beautiful'
- causatives from primary extension neuters with ?- classifier (76-77, 201)
na-...'a' 'O hangs' -> na-O-?-'a' 'hang O up'
- causatives from primary intransitive action themes (76-77, 204)
ti-ch'id 'grow tired' -> O-ti-?-ch'id 'tire O out'
While Golla does not generalize about the semantics of verb themes that are compatible with causative ?-, several preliminary generalizations can be made. Firstly, in the three cases described by Golla, O [the undergoer] is neither controlling nor agentive; O is largely patientive in all cases. Secondly, the causer appears to be acting directly on O. Thirdly, none of the examples given (including the examples above) involve the causativization of a base-transitive theme.
|-vkar-/-cete-||'let, allow, permit, cause, compel'|
|-te-||'let, allow, cause, compel'|
|-rqe-||'intentionally or deliberately cause'|
|-cetaar-||'try to cause'|
|-narqe-||'tend to cause'|
|-naite-||'tend not to cause'|
|-cir-||'let, wait for, make'|
|-(r/l)i -||'become or cause to become'|
Kinyarwanda uses periphrastic causatives and morphological causatives.
The periphrastic causatives use the verbs -teer- and -tum-, which mean cause. With -teer-, the original S becomes the O of the main clause, leaving the original verb in the infinitive, just like in English::160-1
|"The children left."|
|"The man caused the children to go.|
With -túm-, the original S remains in the embedded clause and the original verb is still marked for person and tense::161-2
|"I wrote many letters.|
|"The girl caused me to write many letters."|
Derivational causatives use the -iish- morpheme, which can be applied to intransitives (3) or transitives (4)::164
|"The children are sleeping."|
|"The woman is putting the children to sleep."|
|"The children are reading the books."|
|"The man is making the children read the books."|
The suffix -iish- implies an indirect causation (similar to English have in "I had him write a paper"), but other causatives imply a direct causation (similar to English make in "I made him write a paper").:166
One of the more direct causation devices is the deletion of what is called a "neutral" morpheme -ik-, which indicates state or potentiality. Stems with the -ik- removed can take -iish, but the causation is then less direct::166
|-mének-||"be broken"||-mén-||"break"||-méneesh-||"have (something) broken"|
|-sáduk-||"be cut"||-sátur-||"cut"||-sátuz-||"have (something) cut"|
Another direct causation maker is -y- which is used for some verbs::167
|"The water is being warmed."|
|"The woman is warming the water."|
|"The man is having the woman warm the water.|
In Esperanto, the suffix -ig- can be added to any kind of word:
...verbs like let, make, and have together with their complements are often called causitive verbs or constructions since one agent is (to one degree or another) 'causing' another to act.
