What is the meaning of the name Mairwen ?

The baby name Mairwen is a Female name , 2 syllables long and is pronounced MYR-wen (IPA: /ˈmaɪrwɛn/).

Mairwen is Welsh in Origin.

Mairwen is a modern Welsh compound formed from Mair - the Welsh form of Mary (from Hebrew Miryam via Latin Maria) - and -wen, the soft-mutated feminine of gwen “white, fair, blessed” (< Proto-Celtic *windos). The sense is “Mary the fair/blessed,” sometimes rendered “fair Mary” or “blessed Mary.” In Welsh phonology the initial g- of gwen lenites to w- after a feminine element, yielding wen. Use appears chiefly in Wales from the late 19th century onward, aligning with the revival of native -wen names (Bronwen, Arianwen, Anwen). It remains uncommon but recognizably Welsh, occasionally adopted by the diaspora. Established short forms include Mai and Mair; related equivalents are Mair and Mari for Mary, while cognate -wen names include Gwen, Wenna, and Bronwen. Spelling with -wen marks the feminine; the -wyn ending is masculine in Welsh and not a variant here. Approximate pronunciation: MYRE-wen.
