Because the Greek romantic comedy Never on Sunday was released in October of 1960. It starred Greek actress Melina Mercouri as a free-spirited prostitute named Ilya.
The movie was a big hit, and Melina Mercouri was nominated for Best Actress in a Leading Role (she lost to Elizabeth Taylor). The film earned four other nominations as well, but only won the Best Song category.
Interestingly, the trailer for the film starts with a string of names: “On Monday, it’s Tonio. On Tuesday, Boris. Wednesday is Spiro the fisherman’s day. And on Thursday, Jorgo’s the lucky fellow. Friday is devoted to Homer…”
Most sources classify the name Ilya and similar names (Iliya, Illya, Ilia, etc.) as male names — specifically, as forms of Elijah/Elias. So my best guess on the character name is that it was a nickname for Iliana, the feminine form of the Greek name Ilias (yet another form of Elijah/Elias).
Do you like the name Ilya? Do you prefer it as a girl name or as a boy name?
