The Etain (or more properly Étaín) of Irish mythology was a beautiful fairy turned into a fly (or in some versions, a butterfly), by a jealous queen. The insect Étaín fell into a glass of milk and was swallowed by yet another queen, then reborn as a beautiful maiden. Its pronunciation is similar to the number eighteen.

This name of a mythical beauty transformed into a scarlet fly by a jealous wife is popular in its native land; here, while pleasant to the ear, it's bewildering on paper.

A name possibly derived from Etain, an ancient Irish sun and horse goddess whose name is still used. Adina is a related choice.

Modern Irish form of the mythological name Étaín.

Still not far enough removed from one of the seven deadly sins.

A more name-like take on Envy.

We understand the appeal — similar to Evie, a word name — but envy is not a quality you want to incite in your child.
