In
linguistics, 'synaeresis' (Greek συναίρεσις) is the contraction of two
vowels into a
diphthong (or
long vowel). If synaeresis is used against convention, it may serve as a
rhetorical figure (a
metaplasm). The opposite phenomenon is known as
diaeresis.
In
historical linguistics, such contractions often result after the
regular loss of a consonant that used to separate the two vowels. In this case, the resulting vowel or diphthong will typically carry a
circumflex intonation.
