bisexual (adj.) Look up bisexual at Dictionary.com
1824, "having the organs of both sexes in one being, hermaphroditic;" see bi- "two" + sexual. Meaning "attracted to both sexes" is from 1914; the noun in this sense is attested from 1922, and compare bisexuality. Not in general use until 1950s. Ambisexual was proposed in this sense early 20c.
I suggest that the term ambisexuality be used in psychology instead of the expression "bisexual predisposition." This would connote that we understand by this predisposition, not the presence of male and female material in the organism (Fliess), nor of male and female sex hunger in the mind, but the child's psychical capacity for bestowing his erotism, originally objectless, on either the male or the female sex, or on both. [S. Ferenczi, "Sex in Psycho-Analysis," transl. Ernest Jones, Boston, 1916]
Bisexous (1838) and bisexuous (1856) were used in the sense of "hermaphrodite."

"attraction to both sexes" 1892, in translation of Krafft-Ebing; see bisexual + -ity. Earlier "quality of having the organs of both sexes" (1850).
bishop (n.) Look up bishop at Dictionary.com
Old English bisceop "bishop, high priest (Jewish or pagan)," from Late Latin episcopus, from Greek episkopos "watcher, (spiritual) overseer," a title for various government officials, later taken over in a Church sense, from epi- "over" (see epi-) + skopos "one that watches, one that looks after; a guardian, protector" (from PIE root *spek- "to observe"). Given a specific sense in the Church, but the word also was used in the New Testament as a descriptive title for elders, and continues as such in some non-hierarchical Christian sects.
A curious example of word-change, as effected by the genius of different tongues, is furnished by the English bishop and the French évêque. Both are from the same root, furnishing, perhaps the only example of two words from a common stem so modifying themselves in historical times as not to have a letter in common. (Of course many words from a far off Aryan stem are in the same condition.) The English strikes off the initial and terminal syllables, leaving only piscop, which the Saxon preference for the softer labial and hissing sounds modified into bishop. Évêque (formerly evesque) merely softens the p into v and drops the last syllable. [William S. Walsh, "Handy-Book of Literary Curiosities," Philadelphia, J.B. Lippincott, 1892]
Late Latin episcopus in Spanish became obispo, in Italian vescovo, in Welsh esgob. The Germanic forms include Old Saxon biscop, Old High German biscof. Further afield it became Lithuanian viskupas, Albanian upeshk, Finnish piispa. A once-popular pun on it was bite-sheep (1550s, also in German, biss-schaf). The chess piece (formerly archer, before that alfin) was so called from 1560s.
bishopric (n.) Look up bishopric at Dictionary.com
Old English bisceoprice "diocese, province of a bishop," from bishop + rice "realm, dominion, province," from Proto-Germanic *rikja "rule," from PIE root *reg- "move in a straight line," with derivatives meaning "to direct in a straight line," thus "to lead, rule."

bison (n.) Look up bison at Dictionary.com
c. 1600, "European wild ov," from French bison (15c.), from Latin bison "wild ox," borrowed from Proto-Germanic *wisand- "aurochs" (source also of Old Norse visundr, Old High German wisunt "bison," Old English/Middle English wesend, which is not attested after c. 1400). Possibly ultimately of Baltic or Slavic origin, and meaning "the stinking animal," in reference to its scent while rutting (see weasel).

The animal formerly was widespread on the continent, including the British Isles, but in 20c. survived in the wild only on a forest reserve in Poland. Not to be confused with the aurochs. The name was applied 1690s to the North American species commonly mis-called a buffalo, which formerly ranged as far as Virginia and Georgia but by 1902 was deemed by Century Dictionary "apparently soon to become extinct as a wild animal." It has since recovered numbers on federal land. Related: Bisontine

Another guess is that it is from bistraud "a little shepherd," a word of the Poitou dialect, from biste "goat."

bitch (v.) Look up bitch at Dictionary.com
"to complain," attested at least from 1930, perhaps from the sense in bitchy, perhaps influenced by the verb meaning "to bungle, spoil," which is recorded from 1823. But bitched in this sense seems to echo Middle English bicched "cursed, bad," a general term of opprobrium (as in Chaucer's bicched bones "unlucky dice"), which despite the hesitation of OED, seems to be a derivative of bitch (n.).
bitch (n.) Look up bitch at Dictionary.com
Old English bicce "female dog," probably from Old Norse bikkjuna "female of the dog" (also of the fox, wolf, and occasionally other beasts), which is of unknown origin. Grimm derives the Old Norse word from Lapp pittja, but OED notes that "the converse is equally possible." As a term of contempt applied to women, it dates from c. 1400; of a man, c. 1500, playfully, in the sense of "dog." Used among male homosexuals from 1930s. In modern (1990s, originally African-American vernacular) slang, its use with reference to a man is sexually contemptuous, from the "woman" insult.
BITCH. A she dog, or doggess; the most offensive appellation that can be given to an English woman, even more provoking than that of whore. ["Dictionary of the Vulgar Tongue," 1811]

1925, U.S. slang, "sexually provocative;" later (1930s) "spiteful, catty, bad-tempered" (usually of females); from bitch + -y (2). Earlier in reference to male dogs thought to look less rough or coarse than usual.
Mr. Ramsay says we would now call the old dogs "bitchy" in face. That is because the Englishmen have gone in for the wrong sort of forefaces in their dogs, beginning with the days when Meersbrook Bristles and his type swept the judges off their feet and whiskers and an exaggerated face were called for in other varieties of terriers besides the wire haired fox. [James Watson, "The Dog Book," New York, 1906]
