History & Origin

Kain rewrites the biblical Cain, whose Hebrew form Qayin ties to the idea of acquiring or getting, and sometimes to 'spear' or 'smith'. In scripture the name belongs to the firstborn of Adam and Eve. The K- spelling gives the old name a sharper, more modern look.

Variants such as Cain, Qayin, and the accented Káin and Kaïn show the name across biblical and contemporary forms. The single strong syllable gives it a blunt, striking sound.

Did you know? Kain appears in the Old Testament, which helped preserve it across centuries of Jewish and Christian naming traditions.
