|Voiced alveolar lateral flap|
The voiced alveolar lateral flap is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨?⟩, a fusion of a rotated lowercase letter ⟨r⟩ with a letter ⟨l⟩. Approved in 1928, the symbol represented a sound intermediate between and  or between [r] and [l] until 1979 when its value was redefined as an alveolar lateral flap.
Some languages that are described as having a lateral flap actually have a flap that is indeterminate with respect to centrality, and may surface as either central or lateral, either in free variation or allophonically depending on surrounding vowels and consonants.
