bowel (n.) Look up bowel at Dictionary.com
c. 1300, from Old French boele "intestines, bowels, innards" (12c., Modern French boyau), from Medieval Latin botellus "small intestine," originally "sausage," diminutive of botulus "sausage," a word borrowed from Oscan-Umbrian, from PIE *gwet-/*geut- "intestine" (source also of Latin guttur "throat," Old Norse kviðr "womb," Old English cwið, Gothic qiþus "belly, womb," German kutteln "guts, chitterlings").

Greek splankhnon (from the same PIE root as spleen) was a word for the principal internal organs, which also were felt in ancient times to be the seat of various emotions. Greek poets, from Aeschylus down, regarded the bowels as the seat of the more violent passions such as anger and love, but by the Hebrews they were seen as the seat of tender affections, especially kindness, benevolence, and compassion. Splankhnon was used in Septuagint to translate a Hebrew word, and from thence early Bibles in English rendered it in its literal sense as bowels, which thus acquired in English a secondary meaning of "pity, compassion" (late 14c.). But in later editions the word often was translated as heart. Bowel movement is attested by 1874.

"farm, plantation," from Dutch bowerij "homestead farm" (from the same source as bower); a Dutch word probably little used in America outside New York, and there soon limited to one road, The Bowery, that ran from the built-up part of the city out to the plantations in middle Manhattan, attested from 1787; the city's growth soon overran it, and it was noted by 1840 as a commercial district notorious for squalor, rowdiness, and low life. The Bowery boy as an American comic type had a heyday in the 1850s and again around 1900.
Bowery Boy, the typical New York tough of a generation or two ago, named from the street which he chiefly affected .... He rather prided himself on his uncouthness, his ignorance, and his desperado readiness to fight, but he also loved to have attention called to his courage, his gallantry to women, his patriotic enthusiasm, and his innate tenderness of heart. A fire and a thrilling melodrama called out all his energies and emotions. [Walsh, 1892]

boy (n.) Look up boy at Dictionary.com
mid-13c., boie "servant, commoner, knave, boy," of unknown origin. Possibly from Old French embuie "one fettered," from Vulgar Latin *imboiare, from Latin boia "leg iron, yoke, leather collar," from Greek boeiai dorai "ox hides." (Words for "boy" double as "servant, attendant" across the Indo-European map -- compare Italian ragazzo, French garçon, Greek pais, Middle English knave, Old Church Slavonic otroku -- and often it is difficult to say which meaning came first.)

But it also appears to be identical with East Frisian boi "young gentleman," and perhaps with Dutch boef "knave," from Middle Dutch boeve, perhaps from Middle Low German buobe. This suggests a gradational relationship to babe. For a different conjecture:
In Old English, only the proper name Boia has been recorded. ME boi meant 'churl, servant' and (rarely) 'devil.' In texts, the meaning 'male child' does not antedate 1400. ModE boy looks like a semantic blend of an onomatopoeic word for an evil spirit (*boi) and a baby word for 'brother' (*bo). [Liberman]

A noticable number of the modern words for 'boy', 'girl', and 'child' were originally colloquial nicknames, derogatory or whimsical, in part endearing, and finally commonplace. These, as is natural, are of the most diverse, and in part obscure, origin. [Buck]
Used slightingly of young men in Middle English; meaning "male negro slave or Asian personal servant of any age" attested from c. 1600. Exclamation oh, boy attested from 1892.
