What is the meaning of the name Clydai ?

Clydai is Welsh in Origin.

Clydai is a rare Welsh given name linked to the medieval saint Clydaï, whose dedication survives at Clydey (Welsh: Clydau) in Pembrokeshire. Its elements are usually read from Welsh clyd “sheltered, snug, warm,” with a formative ending -aï, yielding the sense “the sheltered one” or “of the sheltered places.” The name is therefore tied both to landscape and sanctuary, a nuance reflected in local church and place-name history.

Documented chiefly in toponyms and hagiography rather than in baptismal rolls, Clydai has seen only occasional modern use, sometimes as a unisex choice among families celebrating Welsh roots. Attested and variant forms include Clydaï (with diaeresis), Clydey (the anglicized parish name), and Clydau (the plural place-name); Clydawg is a distinct but historically adjacent saint’s name. Some families adapt it to Clyde for ease abroad, though that form is etymologically Scottish. Overall, Clydai offers a distinctive, quietly poetic option with deep regional resonance.
