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. => catastrophe
apostrophe (n.)
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.
