1520s, "state of expectation," from Anglo-French abeiance "suspension," also "expectation (especially in a lawsuit)," from Old French abeance "aspiration, powerful desire," noun of condition from abeer "aspire after, gape, open wide," from à "at" (see ad-) + ba(y)er "be open," from Latin *batare "to yawn, gape" (see abash).

Originally in French a legal term, "condition of a person in expectation or hope of receiving property;" it turned around in English law to mean "condition of property temporarily without an owner" (1650s). Hence "state of suspended action or existence." The French verb baer is also the source of English bay (n.2) "recessed space," as in bay window.

"abolish by authoritative act, repeal," 1520s, from Latin abrogatus, past participle of abrogare "to annul, repeal (a law)," from ab "off, away from" (see ab-) + rogare "propose (a law), ask, request," apparently a figurative use of a PIE verb meaning literally "to stretch out (the hand)," from root *reg- "move in a straight line." Form abrogen, from Old French abroger, is recorded from early 15c. Related: Abrogated; abrogating; abrogative.

1520s, "hasten the occurrence of;" 1590s, "make quicker" (implied in accelerating), from Latin acceleratus, past participle of accelerare "to hasten, quicken" (trans.), "make haste" (intrans.), from ad "to" (see ad-) + celerare "hasten," from celer "swift," which is perhaps from PIE *keli- "speeding" (see celerity). The intransitive sense of "go faster, become faster" in English is from 1640s. Related: Accelerated; accelerative.

type of low, nocturnal, burrowing, carnivorous animal, 1520s, perhaps from bage "badge" (see badge) + reduced form of -ard "one who carries some action or possesses some quality," suffix related to Middle High German -hart "bold" (see -ard). If so, the central notion is the badge-like white blaze on the animal's forehead (as in French blaireau "badger," from Old French blarel, from bler "marked with a white spot;" also obsolete Middle English bauson "badger," from Old French bauzan, literally "black-and-white spotted"). But blaze (n.2) was the usual word for this.

An Old English name for the creature was the Celtic borrowing brock; also græg (Middle English grei, grey). In American English, the nickname of inhabitants or natives of Wisconsin by 1833.

1520s, "mystical interpretation of the Old Testament," later "an intriguing society, a small group meeting privately" (1660s), from French cabal, which had both senses, from Medieval Latin cabbala (see cabbala). Popularized in English 1673 as an acronym for five intriguing ministers of Charles II (Clifford, Arlington, Buckingham, Ashley, and Lauderdale), which gave the word its sinister connotations.

1520s, "deck with something becoming or ornamental, adorn, beautify," from Latin decoratus, past participle of decorare "to decorate, adorn, embellish, beautify," from decus (genitive decoris) "an ornament; grace, dignity, honor," from PIE root *dek- "to take, accept."

Earlier was decoren (early 15c.) with past-participle adjective decorat. Meaning "confer distinction upon by means of a badge or medal of honor" is from 1816. Related: Decorated; decorating.

Old English æl "eel," from Proto-Germanic *ælaz (source also of Old Frisian -el, Middle Dutch ael, Dutch aal, Old Saxon and Old High German al, German Aal, Old Norse all), which is of unknown origin, with no certain cognates outside Germanic. Used figuratively for slipperiness from at least 1520s.

"quality of being effectual, producing the desired effect," 1520s, from Latin efficacia "efficacy, efficiency," from efficax (genitive efficacis) "powerful, effectual, efficient," from stem of efficere "work out, accomplish" (see effect (n.)).

Earlier in English in the same sense was efficace (c. 1200), from Old French eficace (14c.), from Latin efficacia; also efficacite (early 15c.), from Latin efficacitatem.

1520s, "low G, lowest note in the medieval musical scale" (the system of notation devised by Guido d'Arezzo), a contraction of Medieval Latin gamma ut, from gamma, the Greek letter, used in medieval music notation to indicate the note below the A which began the classical scale, + ut (later replaced by do for greater sonority), the low note on the six-note musical scale that took names from syllables sung to those notes in a Latin sapphic hymn for St. John the Baptist's Day:

Ut  queant laxis re sonare fibris

Mira gestorum famuli tuorum,

Solve pollutis labiis reatum,

Sancte Iohannes.

The ut being the conjunction "that." Gamut also was used for "range of notes of a voice or instrument" (1630s), also "the whole musical scale," hence the figurative sense of "entire scale or range" of anything, first recorded 1620s. When the modern octave scale was set early 16c., si was added, changed to ti in Britain and U.S. to keep the syllables as different from each other as possible. Ut later was replaced by more sonorous do (n.). See also solmization.

1520s, "to make a brief, harsh, grating sound," often in reference to bird screeches; the word often is said to be echoic or imitative; compare jargon (n.), jay (n.), garrulous. Figurative sense of "have an unpleasant effect on" is from 1530s; that of "cause to vibrate or shake" is from 1560s. Related: Jarred; jarring. As a noun in this sense from 1540s.
