Glais is Celtic, Irish, Scottish Gaelic in Origin.

Glais is a rare Celtic given name rooted in Welsh and Goidelic languages. In Welsh, glais denotes a “stream” or “rivulet,” while in Irish and Scottish Gaelic the closely related glaise bears the same meaning; both likely trace to a Common Celtic root for “stream,” and sit alongside the adjectival glas, “blue‑green/grey,” evoking water’s hue. As such, the name carries the sense of “stream” and, by association, “blue‑green.”

Use as a personal name is uncommon; Glais more often appears in toponyms and surnames. Examples include Y Glais in Swansea and the Scottish family name Douglas, from dubh “dark” + glais “stream.” Contemporary parents sometimes adopt Glais as a nature-leaning, gender‑neutral choice. Variants and related forms include Glaise (Irish/Scottish Gaelic), Glas (Welsh, as a color name), and the Welsh feminine Glesni (“blueness/greenery”).
