Where this word comes from
From Middle Welsh blwyð, from Proto-Brythonic *bluɨð, from Proto-Celtic *bleidū (“year”), related to *bleidanī (the source of blwyddyn and Old Irish blíadain), possibly from Proto-Indo-European *bʰleyd- (“pale”), though the semantic connection is weak. See also Lithuanian blai̇̃vas (“whitish, blue, sober”), Proto-West Germanic *blait, Albanian blehurë. Celtic cognates include Cornish bloodh, Breton bloaz; Old Breton blened, Welsh blynedd.
