bylgja f (weak jōn-stem)[1]

Etymology

It is inherited from Proto-Germanic *bulgijō (“wave, billow”),[1] a zero-grade noun made to the strong verb Proto-Germanic *belganą (“to swell”),[2][3] which goes back to Proto-Indo-European *bʰelǵʰ- (“to swell”).[1] Outside Norse the noun survives in Middle Low German bulge (“wave; skin bag”) and Middle High German bulge (“storm wave; leather bag”).[2][4] Within Old Norse it belongs with belgr (“skin bag”), bólginn (“swollen”) and bólga (“swelling”).[5][6]

Earliest recorded meaning

Menota's first record is bylgium in the manuscript Holm perg 6 fol of 1250–1300.[7] ONP's first dated citations are from Konungs skuggsjá in a manuscript of 1275, where the sun in spring byðr stærkum bylgium oc brattum barum at hogværaz mæð minnkannda afle “bids the strong billows and steep waves grow calm with lessening force”.[8]

Semantic evolution

ONP glosses it “wave, heavy sea, breaker” and perhaps “surf”, and finds it most often in religious works.[8] In poetry Bylgja is one of the daughters of Ægir, the waves personified,[9][10] and bylgju log “flame of the wave” is a kenning for gold.[11][10]

The word continues as Icelandic, Faroese and Nynorsk bylgja, Swedish bölja and Danish bølge.[5][12] English billow, recorded from the 1550s, is from the Old Norse word.[13][4][14]
