apostrophe: [17] Apostrophe comes originally from the Greek phrase prosōidiā apóstrophos, literally ‘accent of turning away’, hence, a mark showing where a letter or sound has been omitted. Apóstrophos itself was derived from the compound verb apostréphein, formed from the prefix apo- ‘away’ and the verb stréphein ‘turn’ (related to the second element of catastrophe [16], whose Greek original meant literally ‘overturning’). English acquired the word via French and Latin.

apostrophe (n.)youdaoicibaDictYouDict
mark indicating omitted letter, 1580s, from Middle French apostrophe, from Late Latin apostrophus, from Greek apostrophos (prosoidia) "(the accent of) turning away," thus, a mark showing where a letter has been omitted, from apostrephein "avert, turn away," from apo- "from" (see apo-) + strephein "to turn" (see strophe).

In English, the mark often represents loss of -e- in -es, possessive ending. It was being extended to all possessives, whether they ever had an -e- or not, by 18c. Greek also used this word for a "turning aside" of an orator in speech to address some individual, a sense first recorded in English 1530s.
