Etymology

It is inherited from Middle English bulge, also boulge,[2] borrowed from Old French boulge, also bouge,[3][4][5][6] or directly borrowed from Latin bulga (“leather bag, knapsack”).[3][7] The Anglo-Norman noun is recorded from about 1185 for a bag or pouch.[8] The Latin word is of Gaulish origin,[3][9][5] as Festus already said, according to Klein;[10] Barnhart and Klein compare Old Irish bolg (“bag”),[6][10] bolgaim (“I swell”), Welsh bol (“belly”) and Breton bolc'h (“flax pod”),[10] and Etymonline and the American Heritage Dictionary trace it to Proto-Indo-European *bʰelǵʰ- (“to swell”).[7][11] Through the diminutive bougette the same word gave budget,[12][6] and Weekley thought it ultimately related to belly and bellows.[13] The sense "bottom of a ship's hull" is of obscure origin and is connected with bilge,[5][3] which Skeat calls a doublet of the word.[14] The verb was formed from the noun in English;[3][7][6] Merriam-Webster's Collegiate traces it instead to bolgen,[15] and Merriam-Webster Unabridged takes the verb as probably an alteration of bilge.[16] Johnson (1755) held that the verb was originally written bilge.[17]

Earliest recorded meaning

A wallet or bag, especially one of leather; a water skin: about 1230, in Hali Meidenhad,[3][2] which compares a pregnant woman's swelling belly to a water bulge.[2] Barnhart dates it probably to about 1200.[6]

Semantic evolution

The bag sense died out in the early 17th century,[3][9] and about 1400 the word was also used for a hump.[3] Its later senses of swelling and protruding presumably come from the shape of a full bag,[4][12] as with belly and bellows, which also first meant "bag".[12] At sea the word meant the bottom of a ship's hull from 1622,[3][15] now generally replaced by bilge,[3] and the verb first meant to stave in a ship's bottom (1570) or, of a ship, to strike and break its bilge (1581).[3] The verb "to swell out" is recorded from 1677 in Barnhart;[6] the OED dates it to 1679, used of a wall that leans out beyond its base;[3] Etymonline dates the noun "a rounded protuberance" by the 1620s,[7] the OED from 1741.[3] American slang gave to have the bulge on, to have the advantage over (1841),[3][18] and the 20th century added the bulging part of a military front (1927), a temporary rise in numbers, as of school-age children after a rise in the birth rate (1930), and the central part of a spiral galaxy (1943).[3] The Battle of the Bulge was the German counteroffensive of 1944 in Belgium.[19] In dialect, from Ireland to Somerset, the verb could also mean to batter something out of shape or dent it.[20]
