Variant of Angelique, from Greek angelos meaning "messenger" or "angelic."
Angellique carries the layered history of Angelique, ultimately from Greek angelos, meaning messenger. In French form it feels ornate and lightly theatrical, with the extra l adding a softer, more decorative profile.
It belongs to the wide family of angel names that have long suggested purity, protection, and radiance, but this spelling gives the familiar idea a more embellished, couture-like finish. In modern use, Angellique feels rare and polished rather than traditional. It sounds at home in settings that favor elegant feminine names with a classic core and a contemporary flourish. Because the root is so familiar, the spelling does most of the work: it turns a well-known concept into something more individualized, almost like a familiar emblem recast in a more lyrical key.
