About the name
Lainey is a diminutive of Elaine, which is the Old French form of Helen — so it inherits the same contested Greek root, most plausibly the one meaning torch or bright light. Elaine reached English through Arthurian romance as the lady of Astolat.
The -ey ending is what makes it modern: the same move that turns Frances into Frankie and Josephine into Josie. It has climbed hard since the 2010s and sits at number 30 in the US, far above Elaine itself.
It is already a diminutive and does not shorten further. Two syllables want two or three (Lainey Josephine, Lainey Maeve). On our vibe map it is Modern Minimalist with a Y2K Nostalgic ear.
