food - What does the word לאַטקעס (latkes) mean?

לאַטקעס is the Yiddish word used for the potato pancakes commonly and commemoratively eaten on Chanukah. Where does the word לאַטקעס come from originally? What exactly does it mean?

Answer

Etymonline gives it as from Russian латка, "pastry", which may have come eventually from Ancient Greek ἐλαία, "olive" (or maybe it means modern Greek ελαία, "olive". I'm not sure).
