billowy (adjective), billowing (adjective), billowiness (noun)
Billow, meaning ‘a great wave or surge’ (usually of the sea) dates back to the mid-16th century. Some linguists think it may have been used in some dialects before then, but there is no recorded evidence to prove it. It came into English from the Old Norse bylgia (a hollow or wave), and can be traced back to the Proto-Germanic bulgjan and the Proto-Indo-European bhelgh-, an extended form of the root bhel– (to blow or swell). Billow is related to the Swedish bölja and the Danish bölge (a billow), and Middle High German bulge (‘a billow’ or ‘a bag’), as well as the Greek phyllon (leaf), the Latin flos (flower), florere (to blossom or flourish) and folium (leaf), the Old Prussian balsinis (a cushion), the Old Norse belgr (a bag or bellows), the Old Irish bolgaim (I swell), blath (blossom or flower) and bolg (bag), the Breton bolc’h (flax pod), the Serbian buljiti (to stare or be bug-eyed) and the Serbo-Croatian blazina (pillow). It is also related to many English words, including bale, ball, balloon, ballot, bold, boulder, boulevard, bowl, bulk, bull, folly, fool and full. The verb, meaning ‘to rise or roll in large waves’ dates back to the late 16th century, and comes from the noun. Both the noun and the verb have been used figuratively since they came into English.
