Aphaeresis (from ἀφαίρεσις, removal) is far less frequent than elision and consists in dropping the initial vowel of a word; it is likewise marked by an apostrophe. Aphaeresis occurs mainly in poetry, when a word starts with a short vowel preceded by a word ending either in a long vowel or in a diphthong; in these cases, authors plainly favoured the loss of the phonetically less important vowel in order to avoid hiatus.
Ex.: μὴ ἐγώ › μὴ 'γώ, not me; ἐγὼ ἐκάλυψα › ἐγὼ 'κάλυψα, I hide.
Aphaeresis sometimes involves changes in word accents. More specifically:
