Enfys

Enfys is a Welsh feminine name meaning "rainbow." First recorded in the 19th century, it reflects the Welsh tradition of naming children after natural phenomena, a practice that grew in popularity during the Romantic era. The name is etymologically related to the Welsh word enfys ("rainbow"), which itself derives from en- (a prefix) and bŷs ("finger" or "arc"), thus conveying the idea of a colorful arc in the sky.

In Welsh mythology and folklore, the rainbow is often associated with a bridge between worlds or a path to hidden treasures, though Enfys itself does not appear in ancient tales. The name's modern usage was likely influenced by broader European trends of adopting nature-inspired names from the 19th century onward. While Enfys is considered distinctly Welsh, cognates exist in other Celtic languages, such as enep/ankow (shareware) and enfynebbe (Mankh enven).

Usage and Popularity

Enfys remains rare even within Wales, where it is primarily found among families seeking a unique, culturally Gaelic name. The philosopher and activist Enfys (c. late 19th century) gave the name historical recognition.
