What Lainey means
Lainey means bright or shining, a sense carried down from Helen through Elaine. The name has no independent root of its own, having formed by clipping Elaine and adding the English -ey ending used to make familiar forms.
Where Lainey comes from
Lainey traces back through Elaine to the Greek Helene, a name of uncertain but widely accepted derivation from a root meaning torch or shining light. Elaine entered English through Old French, where it was the form used in Arthurian romance — Elaine of Astolat appears in the Lancelot cycle and later in Tennyson's retelling. English speakers formed Lainey from Elaine using the same diminutive pattern that produces Josie and Katie, and it has increasingly been given as a full name rather than as a shortening. The spelling Laney is equally common and reflects the same formation.
