If it were your brother, would you use the same word? (I mean: is it ο/η αεροσυνοδός?)
That is correct. The only difference would be the article. Additionally, in the plural there would be no difference at all, except in the accusative.
What would the accusative plural be? Μιλάω στους αερυσυνοδούς και στις αεροσυνοδές?
τις αεροσυνοδούς Only the article is different for masc. and fem. -ός nouns:
Eνικός: ο/ η -ός, του/ της -ού, το/τη -ό
Πληθυντικός: οι/ οι - οί, των/ των - ών, τους/ τις -ούς
The vocative singular is of course different. When you speak to a man use (κύριε) αεροσυνοδέ and say (κυρία) αεροσυνοδός to a woman
Agreed on everything, except the vocative singular. It should be αεροσυνοδέ in both cases.
Maybe we both are right
Κυρία μηχανικέ! (ή μηχανικός)
Γιατρέ! (ή γιατρός)
(I got voc.sing. is -ός for feminines from Stauropoulos' dictionary. )
I agree. Αεροσυνοδός and every word that falls in the same category doesn't sound nice if you call her "αεροσυνοδός" "γιατρός" etc.
I can't reply to your most recent comment, for some reason. Anyway, if you look at the pdf you linked, the η in both examples you give is actually not accented. It is there to give the nominative case. It is possible that other sources might use -ός, though.
Thanks. I misunderstood my link. I thougt (η γιατρός) was a typo for (ή γιατρός), i.e. an alternative. I have corrected it now. Then my only support is Stauropoulos Oxford Greek Learner's Dictionary Really I do not know what is right and I cannot find anything on internet about vocative except the one I gave and which finally gives support to you
Prof. Babiniotis has both: αδελφή or αδερφή as well as αδελφός or αδερφός = brother
etym. αδελφή < αδελφός < ancient δέλφος = μήτρα/ womb
He also gives: χθες/ χτες ή εχθές/ εχτές = 1.yesteday 2.very recently 3. το χθες the past
