Cayll is Irish in Origin.

Cayll is a modern English given name, usually pronounced KAYL. It reads as a creative respelling in the Kayl/Kael family and is most often linked to two streams: Gaelic and Hebrew. From the Gaelic side, it parallels Irish Cael and Scottish–Irish Kyle, both tied to caol, meaning “slender” or “narrow strait.” From the Hebrew side, it can function like Cale, a clipped form of Caleb, whose traditional meaning is “wholehearted” or “devoted.” With no medieval attestations, its use emerges in late 20th‑ and early 21st‑century English‑speaking countries.

Variants and near‑cognates include Cael, Kael, Cail, Cale, Cayle, Cayl, Kail, Kyle, and Kale; short forms such as Cay or Kay occur in casual use. Cayll is rare and largely unisex in practice, though more often given to boys. Parents may choose it for its sleek, contemporary look while retaining heritage readings of “slender/from the strait” or “wholehearted.”
