Shay has an old-fashioned feel due to its association with the word for a kind of horse-drawn carriage and at the same time seems modern thanks to its simple straightforwardness. Use Shay as a phonetic equivalent of the Irish surname Shea or the Hebrew male name Shai, or as an abbreviated form of such names as Seamus or Shane.

A variant spelling of either Irish Shea or Hebrew Shai, Shay feels at once vintage and modern.
