The phonology of Portuguese varies among dialects, in extreme cases leading to some difficulties in intelligibility. This article focuses on the pronunciations that are generally regarded as standard. Since Portuguese is a pluricentric language, and differences between European Portuguese (EP), Brazilian Portuguese (BP) and Angolan Portuguese (AP) can be considerable, varieties are distinguished whenever necessary.
One of the most salient differences between European and Brazilian Portuguese is their prosody. European Portuguese is a stress-timed language, with reduction, devoicing or even deletion of unstressed vowels and a general tolerance of syllable-final consonants. Brazilian Portuguese, on the other hand, is of mixed characteristics, and varies according to speech rate, dialect, and the gender of the speaker, but generally possessing a lighter reduction of unstressed vowels, less raising of pre-stress vowels, less devoicing and fewer deletions. At fast speech rates, Brazilian Portuguese is more stress-timed, while in slow speech rates, it can be more syllable-timed. The accents of rural, southern Rio Grande do Sul and the Northeast (especially Bahia) are considered to sound more syllable-timed than the others, while the southeastern dialects such as the mineiro, in central Minas Gerais, the paulistano, of the northern coast and eastern regions of São Paulo, and the fluminense, along Rio de Janeiro, Espírito Santo and eastern Minas Gerais as well the Federal District, are most frequently essentially stress-timed. Also, male speakers of Brazilian Portuguese speak faster than female speakers and speak in a more stress-timed manner.
Brazilian Portuguese disallows some closed syllables: coda nasals are deleted with concomitant nasalization of the preceding vowel, even in learned words; coda /l/ becomes , except for conservative velarization at the extreme south and rhotacism in remote rural areas in the center of the country; the coda rhotic is usually deleted entirely when word-final, especially in verbs in the infinitive form; and /i/ can be epenthesized after almost all other coda-final consonants. This tends to produce words almost entirely composed of open syllables, e.g., magma ['ma?im?]. In European Portuguese, similarly, epenthesis may occur with [?], as in magma ['mam?] and afta ['af?t?].
The consonant inventory of Portuguese is fairly conservative.[context needed] The medieval Galician-Portuguese system of seven sibilants (/ts, dz/, /? ?/, /t?/, and apicoalveolar /s? z?/) is still distinguished in spelling (intervocalic c/ç z x g/j ch ss -s- respectively), but is reduced to the four fricatives /s z ? ?/ by the merger of /t?/ into /?/ and apicoalveolar /s? z?/ into either /s z/ or /? ?/ (depending on dialect and syllable position), except in parts of northern Portugal (most notably in the Trás-os-Montes region). These changes are known as deaffrication. Other than this, there have been no other significant changes to the consonant phonemes since Old Portuguese. However, several consonant phonemes have special allophones at syllable boundaries (often varying quite significantly between European and Brazilian Portuguese), and a few also undergo allophonic changes at word boundaries. Henceforward, the phrase "at the end of a syllable" can be understood as referring to a position before a consonant or at the end of a word.
There is a variation in the pronunciation of the first consonant of certain clusters, most commonly C or P in cç, ct, pç and pt. These consonants may be variably elided or conserved. For some words, this variation may exist inside a country, sometimes in all of them; for others, the variation is dialectal, with the consonant being always pronounced in one country and always elided in the other. This variation affects 0.5% of the language's vocabulary, or 575 words out of 110,000. In most cases, Brazilians variably conserve the consonant while speakers elsewhere have invariably ceased to pronounce it (for example, detector in Brazil versus detetor in Portugal). The inverse situation is rarer, occurring in words such as fa(c)to and conta(c)to (consonants never pronounced in Brazil, pronounced elsewhere). Until 2009, this reality could not be apprehended from the spelling: while Brazilians did not write consonants that were no longer pronounced, the spelling of the other countries retained them in many words as silent letters, usually when there was still a vestige of their presence in the pronunciation of the preceding vowel. This could give the false impression that European Portuguese was phonologically more conservative in this aspect, when in fact it was Brazilian Portuguese that retained more consonants in pronunciation.
Syllables have the maximal structure of (C)(C)V(C). The only possible codas in European Portuguese are [?], [?] and /?/ and in Brazilian Portuguese /s/ and /?~?/.
The two rhotic phonemes /?/ and /?/ contrast only between oral vowels, similar to Spanish. Elsewhere, their occurrence is predictable by context, with dialectal variations in realization. The rhotic is "hard" (i.e., /?/) in the following circumstances:
The realization of the "hard" rhotic /?/ varies significantly across dialects.
This restricted variation has prompted several authors to postulate a single rhotic phoneme. Câmara (1953) and Mateus & d'Andrade (2000) see the soft as the unmarked realization and that instances of intervocalic [?] result from gemination and a subsequent deletion rule (i.e., carro /'karo/ > ['kau] > ['ka?u]). Similarly, Bonet & Mascaró (1997) argue that the hard is the unmarked realization.
In addition to the phonemic variation between /?/ and /?/ between vowels, up to four allophones of the "merged" phoneme /R/ are found in other positions:
The default hard allophone is some sort of voiceless fricative in most dialects, e.g., [?] [h] [x], although other variants are also found. For example, a trill [r] is found in certain conservative dialects down São Paulo, of Italian-speaking, Spanish-speaking, Arabic-speaking, or Slavic-speaking influence. The other trill [?] is found in areas of German-speaking, French-speaking, and Portuguese-descended influence throughout coastal Brazil down Espírito Santo, most prominently Rio de Janeiro.
The syllable-final allophone shows the greatest variation:
Throughout Brazil, deletion of the word-final rhotic is common, regardless of the "normal" pronunciation of the syllable-final allophone. This pronunciation is particularly common in lower registers, although found in most registers in some areas, e.g., Northeast Brazil, and in the more formal and standard sociolect. It occurs especially in verbs, which always end in R in their infinitive form; in words other than verbs, the deletion is rarer and seems not to occur in monosyllabic non-verb words, such as mar. Evidence of this allophone is often encountered in writing that attempts to approximate the speech of communities with this pronunciation, e.g., the rhymes in the popular poetry (cordel literature) of the Northeast and phonetic spellings (e.g., amá, sofrê in place of amar, sofrer) in Jorge Amado's novels (set in the Northeast) and Gianfrancesco Guarnieri's play Eles não usam black tie (about favela dwellers in Rio de Janeiro).
The soft realization is often maintained across word boundaries in close syntactic contexts (e.g., mar azul ['maa'zuw] 'blue sea').
Portuguese has one of the richest vowel phonologies of all Romance languages, having both oral and nasal vowels, diphthongs, and triphthongs. A phonemic distinction is made between close-mid vowels /e o/ and the open-mid vowels /? ?/, as in Italian, Catalan and French, though there is a certain amount of vowel alternation. European Portuguese has also two central vowels, one of which tends to be elided like the e caduc of French.
The central closed vowel /?/ only occurs in European Portuguese when e is unstressed, e.g. presidente [pzi'ð?t?]; as well as in Angola, but it only occurs at last syllables, e.g. presidente [p?ezi'd?t?]. However, /?/ does not exist in Brazil, e.g. presidente [p?ezi'd?t?i].
In Angola, /?/ and /a/ merge to [a], and /?/ appears only in final syllables rama /'?am?/. The nasal // becomes open [ã].
Portuguese uses vowel height to contrast stressed syllables with unstressed syllables; the vowels /a ? e ? o/ tend to be raised to [? ? ? ? u] (although [?] occurs only in EP and AP) when they are unstressed (see below for details). The dialects of Portugal are characterized by reducing vowels to a greater extent than others. Falling diphthongs are composed of a vowel followed by one of the high vowels /i/ or /u/; although rising diphthongs occur in the language as well, they can be interpreted as hiatuses.
European Portuguese possesses quite a wide range of vowel allophones:
The exact realization of the /?/ varies somewhat amongst dialects. In Brazil, [a] and [?] are in complementary distribution: [? ~ ?] occurs in word-final unstressed syllables, while [? ~ ?] occurs in stressed syllables before an intervocalic /m/, /n/, or /?/; in these phonetic conditions, [? ~ ?] can be nasalized. Unstressed [a ~ ? ~ ?] occurs in all other environments. In European Portuguese, the general situation is similar (with [?] being more prevalent in nearly all unstressed syllables), except that in some regions the two vowels form minimal pairs in some European dialects. In central European Portuguese this contrast occurs in a limited morphological context, namely in verbs conjugation between the first person plural present and past perfect indicative forms of verbs such as pensamos ('we think') and pensámos ('we thought'; spelled ⟨pensamos⟩ in Brazil). proposes that it is a kind of crasis rather than phonemic distinction of /a/ and /?/. It means that in falamos 'we speak' there is the expected prenasal /a/-raising: [f?'l?mu?], while in falámos 'we spoke' there are phonologically two /a/ in crasis: /fa'laamos/ > [f?'lamu?] (but in Brazil both merge, falamos [fa'l?mus]). Close-mid vowels and open-mid vowels (/e ~ ?/ and /o ~ ?/) contrast only when they are stressed. In unstressed syllables, they occur in complementary distribution. In Brazilian Portuguese, they are raised to a high or near-high vowel ([i ~ ?] and [u ~ ?], respectively) after a stressed syllable, or in some accents and in general casual speech, also before it.
According to Mateus and d'Andrade (2000:19), in European Portuguese, the stressed [?] only occurs in the following three contexts:
English loanwords containing stressed /?/ or /?:r/ are usually associated with pre-nasal ⟨a⟩ as in rush, or are influenced by orthography as in clube (club), or both, as in surf/surfe.
European Portuguese possesses a near-close near-back unrounded vowel. It occurs in unstressed syllables such as in pegar [p'?a?] ('to grip'). There is no standard symbol in the International Phonetic Alphabet for this sound. The IPA Handbook transcribes it as /?/, but in Portuguese studies /?/ is traditionally used.
There are very few minimal pairs for this sound: some examples include pregar [p'?a?] ('to nail') vs. pregar [p'?a?] ('to preach'; the latter stemming from earlier preegar < Latin praedic?re),sê ['se] ('be!') vs. sé ['s?] ('see/cathedral') vs. se [s?] ('if'), and pêlo ['pelu] ('hair') vs. pélo ['p?lu] ('I peel off') vs. pelo [p?lu] ('for the'), after orthographic changes, all these three words are now spelled pelo.
Diphthongs are not considered independent phonemes in Portuguese, but knowing them can help with spelling and pronunciation.
|Diphthong||Usual spelling||Example||Meaning||Notes and variants|
|/aj/||ai, ái||pai||'father'||In Brazil, it may be realized as [a] before a post-alveolar fricative /?, ?/, making baixo realized as ['ba?u].|
|/?j/||ai, âi||plaina||'jointer'||In Brazil, except Northern dialects. It occurs before nasal consonants and can be nasalised, as in plaina ['pl?jn?].|
|ei, éi, êi||leite||'milk'||In Greater Lisbon (according to NUTS III, which does not include Setúbal) /e/ can be centralized [?] before palatal sounds (/j, ?, ?, ?, ?/); e.g. roupeiro [?o'p?j?u], brenha ['b(j)], texto ['t?(j)?tu], vejo ['v?(j)?u], coelho [ku'?(j)?u].|
|/ej/||ei, êi||rei||'king'||In several vernacular dialects (most of Portugal, Brazil and Lusophone Africa), "ei" may be realized essentially as [e] in unstressed syllables. Words ending on either -eiro or -eira (like roupeiro [?o'pe?u], bandeira [b'de], brasileiro [b?azi'le?u], brasileira [b?azi'le], etc.), when ei precedes a palatal sound (like queijo ['ke?u], deixa ['de], etc.), or when ei precedes a consonant in general (like manteiga [m'teg?], beiço ['besu]) are optionally monophthongized, depending on the speaker and region (comparable to Spanish ropero, bandera, brasilero, brasilera, queso, deja, manteca, bezo).
However, notice that when ei makes up part of a Greco-Latin loanword (like diarreico, anarreico, etc.), as well as nouns ending on -ei (like rei ['?ej], lei ['lej]) keep their palatal sound /ej/ (/?j/, in case of -eico ending nouns and adjectives). In most stressed syllables, the pronunciation is /ej/. There are very few minimal pairs for /ej/ and /?j/, all of which occur in oxytonic words.
In Greater Lisbon, however, it is always pronounced [?j].
|/?j/||ei, éi||geleia, anéis||'jelly', 'rings'||It only occurs in -el plurals like anéis (plural of anel 'ring').
In Greater Lisbon, however, it is always pronounced [?j].
|/?j/||oi, ói||dói, destrói||'hurts', 'destroys'||Pronounced as /?j/ mostly on -oi ending words like herói 'hero', as well as some verbal conjugations.|
|/uj/||ui||fui||'I went'||Usually stressed.|
|/?w/||au, âu||saudade||'to miss'||In EP, when unstressed. Also occurs in the contraction ao(s). In Brazil, except by Northern dialects, it occurs before nasal consonants and can be nasalized; as in trauma ['twm?].|
|/ew/||eu, êu||seu||'his'||There are very few minimal pairs for /eu/ and /?u/, all occurring in oxytonic words.|
|/iw/||iu||viu||'he saw'||Usually stressed.|
|/ow/||ou||ouro||'gold'||Merges optionally with /o/ in most of modern Portuguese dialects, excluding some regions in northern Portugal.|
There are also some words with two vowels occurring next to each other like in iate and sábio may be pronounced both as rising diphthongs or hiatus. In these and other cases, other diphthongs, diphthong-hiatus or hiatus-diphthong combinations might exist depending on speaker, such as [uw] or even [uw.wu] for suo ('I sweat') and [ij] or even [ij.ji] for fatie ('slice it').
[j] and [w] are non-syllabic counterparts of the vowels /i/ and /u/, respectively. At least in European Portuguese, the diphthongs [?j, aj, ?j, ?j, oj, uj, iw, ew, ?w, aw] tend to have more central second elements [i, u] - note that the latter semivowel is also more weakly rounded than the vowel /u/. In the Lisbon accent, the diphthong [?j] often has an onset that is more back than central, i.e. [j] or even [?j].
|Nasal vowel||Usual spelling||Example||Meaning|
|//||ã, am, an||rã, canto||'frog', 'I sing' or 'corner'|
|/?/||em, en||entro||'I enter'|
|/?/||im, in||vim||'I came'|
|/õ/||õ, om, on||sombra||'shadow'|
Portuguese also has a series of nasalized vowels. Cruz-Ferreira (1995) analyzes European Portuguese with five monophthongs and four diphthongs, all phonemic: /? ? õ ? j? õj? ?j? w? õw?/. Nasal diphthongs occur mostly at the end of words (or followed by a final sibilant), and in a few compounds. Brazilian Portuguese is overall [clarification needed] than European Portuguese due to many external influences including the common language spoken at Brazil's coast at time of discovery, Tupi.
As in French, the nasal consonants represented by the letters ?m n? are deleted in coda position, and in that case the preceding vowel becomes phonemically nasal, e.g. in genro /'u/ ('son-in-law'). But a nasal consonant subsists when it is followed by a plosive, e.g. in cantar [kn'ta?] ('to sing'). Vowel nasalization has also been observed non-phonemically as result of coarticulation, before heterosyllabic nasal consonants, e.g. in soma ['sõm?] ('sum'). Hence, one speaks discriminatingly of nasal vowels (i.e. phonemically so) and nasalized vowels. Additionally, a nasal monophthong // written ?ã? exists independently of these processes, e.g. in romã /?o'm/ ('pomegranate').
The /e-?/ and /o-?/ distinction does not happen in nasal vowels; ?em om? are pronounced as close-mid. In BP, the vowel /a/ (which the letter ?a? otherwise represents) is sometimes phonemically raised to /?/ when it is nasal, and also in stressed syllables before heterosyllabic nasal consonants (even if the speaker does not nasalize vowels in this position): compare for instance dama sã ['d?m? 's] (PT) or ['dm? 's] (BR) ('healthy lady') and dá maçã ['da m?'s] (PT) or ['da ma's] (BR) ('it gives apples'). /a/ may also be raised slightly in word-final unstressed syllables.
Nasalization and height increase noticeably with time during the production of a single nasal vowel in BP in those cases that are written with nasal consonants ?m n?, so that /'u/ may be realized as ['j] or [']. This creates a significant difference between the realizations of ?am? and ?ã? for some speakers: compare for instance ranço real ['s? ?j'al] (PT) or ['s? ?e'aw] (BR) ('royal rancidness') and rã surreal [' su?i'al] (PT) or [' su?e'aw] (BR) ('surreal frog'). (Here  means a velar nasal approximant.) At the end of a word ?em? is always pronounced [?j?] with a clear nasal palatal approximant (see below). Whenever a nasal vowel is pronounced with a nasal coda (approximant or occlusive) the (phonetic) nasalization of the vowel itself is optional.
The following examples exhaustively demonstrate the general situation for BP.
It follows from these observations that the vowels of BP can be described simply in the following way.
With this description, the examples from before are simply /?o'm?/, /'?eN?u/, /sej?/, /kaN'ta?/, /'k?nu/, /'tomu/. But there is no commonly accepted transcription for Brazilian Portuguese phonology.
Vowel nasalization in some dialects of Brazilian Portuguese is very different from that of French, for example. In French, the nasalization extends uniformly through the entire vowel, whereas in the Southern-Southeastern dialects of Brazilian Portuguese, the nasalization begins almost imperceptibly and then becomes stronger toward the end of the vowel. In this respect it is more similar to the nasalization of Hindi-Urdu (see Anusvara). In some cases, the nasal archiphoneme even entails the insertion of a nasal consonant such as [m, n, ?, , w?, ] (compare Polish phonology § Open), as in the following examples:
|Nasal diphthong||Usual spelling||Example||Meaning||Notes and variants|
|/j?/||ãe, ãi||mãe, cãibra||'mom', 'cramp'||In Central and Southern Portugal, it is also the colloquial pronunciation of /?j/, which means mãe and bem rhyme.|
|/?j?/||em||bem||'well'||In Greater Lisbon, it merges to [j], which means mãe and bem rhyme.|
|/?j?/||ui||muito||'very', 'much'||Only nasalized in words derived from muito (including mui).|
|/w?/||am, ão||falam, mão||'they speak', 'hand'|
|/õw? ~ õ/ ||om||bom||'good'||The diphthongation of such nasal vowel is controversial.|
Most times nasal diphthongs occur at the end of the word. They are:
[j?] and [w?] are nasalized, non-syllabic counterparts of the vowels /i/ and /u/, respectively. At least in European Portuguese, the diphthongs [j?, õj?, ?j?, w?] tend to have more central second elements [, ] - note that the latter semivowel is also more weakly rounded than the vowel /u/.
There are also pairs of unrelated words that differ in the height of these vowels, such as besta /e/ ('beast') and besta /?/ ('crossbow'); mexo /e/ ('I move') and mecho /?/ ('I highlight [hair]'); molho /o/ ('sauce') and molho /?/ ('bunch'); corte /?/ ('cut') and corte /o/ ('court'); meta /e/ ('I put' subjunctive) and meta /?/ ('goal'); and (especially in Portugal) para /?/ ('for') and para /a/ ('he stops'); forma /o/ ('mold') and forma /?/ ('shape').
There are several minimal pairs in which a clitic containing the vowel /?/ contrasts with a monosyllabic stressed word containing /a/: da vs. dá, mas vs. más, a vs. à /a/, etc. In BP, however, these words may be pronounced with /a/ in some environments.
Some isolated vowels (meaning those that are neither nasal nor part of a diphthong) tend to change quality in a fairly predictable way when they become unstressed. In the examples below, the stressed syllable of each word is in boldface. The term "final" should be interpreted here as at the end of a word or before word-final -s.

With a few exceptions mentioned in the previous sections, the vowels /a/ and /?/ occur in complementary distribution when stressed, the latter before nasal consonants followed by a vowel, and the former elsewhere.
In Brazilian Portuguese, the general pattern in the southern and western accents is that the stressed vowels /a, ?/, /e, ?/, /o, ?/ neutralize to /a/, /e/, /o/, respectively, in unstressed syllables, as is common in Romance languages. In final unstressed syllables, however, they are raised to /?/, /i/, /u/. In casual BP (as well in the fluminense dialect), unstressed /e/ and /o/ may be raised to /? ~ i/, /? ~ u/ on any unstressed syllable, as long as it has no coda. However, in North-Eastern Brazilian dialects (like in the states of Bahia and Pernambuco), non-final unstressed vowels are open-mid /a/, /?/, /?/.
European Portuguese has taken this process one step further, raising /a, ?/, /e, ?/, /o, ?/ to /?/, /?/, /u/ in all unstressed syllables. The vowels /?/ and /?/ are also more centralized than their Brazilian counterparts. The three unstressed vowels /?, ?, u/ are reduced and often voiceless or elided in fast speech. If /?/ is elided, which mostly it is in the beginning of a word and word finally, the previous consonant becomes aspirated like in ponte (bridge) ['põt?], or if it is /u/ is labializes the previous consonant like in grosso (thick) ['os?].
However, Angolan Portuguese has been more conservative, raising /a/, /e, ?/, /o, ?/ to /a/, /e/, /o/ in unstressed syllables; and to /?/, /?/, /u/ in final unstressed syllables. Which makes it almost similar to Brazilian Portuguese (except by final /?/, which is inherited from European Portuguese).
There are some exceptions to the rules above. For example, /i/ occurs instead of unstressed /e/ or /?/, word-initially or before another vowel in hiatus (teatro, reúne, peão). /?/ is often deleted entirely word-initially in the combination /?sC/ becoming [?C ~ ?C]. Also, /a/, /?/ or /?/ appear in some unstressed syllables in EP, being marked in the lexicon, like espetáculo (spectacle) [?p?'takulu]; these occur from deletion of the final consonant in a closed syllable and from crasis. And there is some dialectal variation in the unstressed sounds: the northern and eastern accents of BP have low vowels in unstressed syllables, /?, ?/, instead of the high vowels /e, o/. However, the Brazilian media tends to prefer the southern pronunciation. In any event, the general paradigm is a useful guide for pronunciation and spelling.
Nasal vowels, vowels that belong to falling diphthongs, and the high vowels /i/ and /u/ are not affected by this process, nor is the vowel /o/ when written as the digraph ⟨ou⟩ (pronounced /ow/ in conservative EP). Nevertheless, casual BP may raise unstressed nasal vowels /?/, /õ/ to [ ~ ?], [ ~ ?], too.
In BP, an epenthetic vowel [i] is sometimes inserted between consonants, to break up consonant clusters that are not native to Portuguese, in learned words and in borrowings. This also happens at the ends of words after consonants that cannot occur word-finally (e.g., /d/, /k/, /f/). For example, psicologia ('psychology') may be pronounced [pisikolo'?i?]; adverso ('adverse') may be pronounced [ad?i'vsu]; McDonald's may be pronounced [mki'dõnawd?is]. In northern Portugal, an epenthetic [?] may be used instead, [p?sikulu'?i?], [?ð?'?su], but in southern Portugal there is often no epenthesis, [psikulu'?i?], [?d'vsu]. Epenthesis at the end of a word does not normally occur in Portugal.
The native Portuguese consonant clusters, where there is not epenthesis, are sequences of a non-sibilant oral consonant followed by the liquids /?/ or /l/, and the complex consonants /ks, kw, ?w/. Some examples:
This section does not cite any sources. (April 2013) (Learn how and when to remove this template message)
When two words belonging to the same phrase are pronounced together, or two morphemes are joined in a word, the last sound in the first may be affected by the first sound of the next (sandhi), either coalescing with it, or becoming shorter (a semivowel), or being deleted. This affects especially the sibilant consonants /s/, /z/, /?/, /?/, and the unstressed final vowels /?/, /i, ?/, /u/.
As was mentioned above, the dialects of Portuguese can be divided into two groups, according to whether syllable-final sibilants are pronounced as postalveolar consonants /?/, /?/ or as alveolar /s/, /z/. At the end of words, the default pronunciation for a sibilant is voiceless, /?, s/, but in connected speech the sibilant is treated as though it were within a word (assimilation):
When two identical sibilants appear in sequence within a word, they reduce to a single consonant. For example, nascer, desço, excesso, exsudar are pronounced with [s] by speakers who use alveolar sibilants at the end of syllables, and disjuntor is pronounced with [?] by speakers who use postalveolars. But if the two sibilants are different they may be pronounced separately, depending on the dialect. Thus, the former speakers will pronounce the last example with [z?], whereas the latter speakers will pronounce the first examples with [s] if they are from Brazil or [?s] if from Portugal (although in relaxed pronunciation the first sibilant in each pair may be dropped). This applies also to words that are pronounced together in connected speech:
Normally, only the three vowels /?/, /i/ (in BP) or /?/ (in EP), and /u/ occur in unstressed final position. If the next word begins with a similar vowel, they merge with it in connected speech, producing a single vowel, possibly long (crasis). Here, "similar" means that nasalization can be disregarded, and that the two central vowels /a, ?/ can be identified with each other. Thus,
In careful speech and in with certain function words, or in some phrase stress conditions (see Mateus and d'Andrade, for details), European Portuguese has a similar process:
Aside from historical set contractions formed by prepositions plus determiners or pronouns, like à/dà, ao/do, nesse, dele, etc., on one hand and combined clitic pronouns such as mo/ma/mos/mas (it/him/her/them to/for me), and so on, on the other, Portuguese spelling does not reflect vowel sandhi. In poetry, however, an apostrophe may be used to show elision such as in d'água.
Primary stress may fall on any of the three final syllables of a word, but mostly on the last two. There is a partial correlation between the position of the stress and the final vowel; for example, the final syllable is usually stressed when it contains a nasal phoneme, a diphthong, or a close vowel. The orthography of Portuguese takes advantage of this correlation to minimize the number of diacritics.
Practically, for the main stress pattern, words that end with: "a(s)", "e(s)", "o(s)", "em(ens)" and "am" are stressed in the penultimate syllable, and those that don't carry these endings are stressed in the last syllable. In the case a word doesn't follow this pattern, it takes an accent according to Portuguese's accentuation rules (these rules might not be followed everytime when concerning personal names and non-integrated loanwords).
Because of the phonetic changes that often affect unstressed vowels, pure lexical stress is less common in Portuguese than in related languages, but there is still a significant number of examples of it:
This section needs expansion. You can help by adding to it. (February 2020)
Tone is not lexically significant in Portuguese, but phrase- and sentence-level tones are important. As in most Romance languages, interrogation on yes-no questions is expressed mainly by sharply raising the tone at the end of the sentence. An exception to this is the word oi that is subject to meaning changes: an exclamation tone means 'hi/hello', and in an interrogative tone it means 'I didn't understand'.
