Bright, shining light
Elainey is a modern diminutive or phonetic variant of Elaine, which itself is the Old French form of Helen. It carries the same etymological roots meaning 'torch' or 'coruscating light.' While rare, it follows the contemporary trend of adding a diminutive 'y' or 'ie' ending to classic names to create a more approachable, youthful feel.
