mid-13c., "monastery or convent devoted to religion and celibacy, headed by an abbot or abbess," from Anglo-French abbeie, Old French abaïe (Modern French abbaye), from Late Latin abbatia, from abbas (genitive abbatis); see abbot. At the dissolution of the monasteries, the name often was kept by abbey churches (as in Westminster Abbey) or estate houses that formerly were abbey residences.

mid-13c., "action of waiting," verbal noun from abiden "to abide" (see abide). It is formally identical with the old, strong past participle of abide (Old English abad), but the modern conjugation is weak and abided is used. The present-to-preterite vowel change is consistent with an Old English class I strong verb (ride/rode, etc.). The meaning "habitual residence" is attested by 1570s.

mid-13c., "widely apart," a contraction of on brode, from Old English on brede, "in width," literally "at wide" (see a- (1) + broad (adj.)). From c. 1300 as "at a distance from each other," hence "out of doors, away from home" (late 14c.) also "at a distance generally" (early 15c.), and the main modern sense, "out of one's country, overseas" (mid-15c.).

mid-13c., "to end at, to border on, touch at the end," from Old French aboter, abuter "join end to end, touch with an end" (13c.), and abouter "join end to end," from à "to" (see ad-) + boter, bouter "to strike, push," from a Germanic source (ultimately from PIE root *bhau- "to strike"). Compare butt (v.). Related: Abutted; abutting.

mid-13c., aquiten, "repay, reciprocate, reward or retaliate for" (a good or bad deed); c. 1300 as "satisfy a debt; redeem (a pledge)," from Old French aquiter, acquiter "pay, pay up, settle a claim" (12c., Modern French acquitter), from a- "to" (see ad-) + quite "free, clear," from Medieval Latin quitus, quittus, from Latin quietus "free" (in Medieval Latin "free from war, debts, etc."), also "calm, resting" (from PIE root *kweie- "to rest, be quiet"). Also in part from Medieval Latin acquitare.

From mid-14c. as "relieve (someone) of an obligation, release from a pledge," hence the meanings "set (an accused person) free from charges, pronounce not guilty," and "discharge one's duty; behave or conduct oneself" (for better or worse), all of which date to late 14c. The notion in the word is "to release or discharge," from an obligation or from accusation, guilt, censure, or suspicion. Related: Acquitted; acquitting.

mid-13c., avauncen (transitive), "improve (something), further the development of," from Old French avancir, avancier "move forward, go forward, set forward" (12c., Modern French avancer), from Vulgar Latin *abanteare (source of Italian avanzare, Spanish avanzar). This is from Late Latin abante "from before," composed of ab "from" (see ab-) + ante "before, in front of, against" (from PIE root *ant- "front, forehead").

Compare French avant "before" (as in avant-garde), which is from the same Late Latin word. The unetymological -d- in English was inserted 16c. on the mistaken notion that initial syllable was from Latin ad-.

It is attested from c. 1300 as "to promote, raise to a higher rank." The intransitive sense of "move forward, move further in front" is by mid-14c.; the transitive meaning "bring forward in place, move (something) forward" is from c. 1500. The meaning "give (money, etc.) before it is legally due" is attested by 1670s. Related: Advanced; advancing. The adjective (in advance warning, etc.) is recorded from 1843.

mid-13c., from Old French ha, las (later French hélas), from ha "ah" + las "unfortunate," originally "tired, weary," from Latin lassus "weary" (from PIE root *‌‌lē- "to let go, slacken"). At first an expression of weariness rather than woe.

"low down," mid-13c.; see a- (1) + low (adj.). Older than below. Nautical use is by c. 1500.

mid-13c., amis "off the mark," also "out of order," literally "on the miss," from a "in, on" (see a- (1)) + missen "fail to hit" (see miss (v.)). From late 14c. as "improper, wrong, faulty;" to take (something) amiss originally (late 14c.) was "to miss the meaning of" (see mistake). Now it means "to misinterpret in a bad sense."

"among," mid-13c., amonges, from among with adverbial genitive -s. The unetymological -t is attested from 16c. (compare amidst).
