Eila is a Hebrew name heard in Israel, due for wider consideration thanks to sound-alike sister Isla, as in actress Fisher. Either way you spell it, the name is simpler than it looks: Pronunciation is I, as in the letter, followed by la. ... But along with other simple names like Ava, Eve, and Ivy, a star nonetheless.
Ela is a female first name. It comes from the Hebrew word Elah meaning Oak. It is a nickname for Elen, Eliška, Elektra, Angela or Eleanor. In Turkish Ela means Hazel.
