Adirondack Mountains is a back-formation from Adirondacks, which was treated as a plural noun but really it is from Mohawk (Iroquoian) adiro:daks "tree-eaters," a name they applied to neighboring Algonquian tribes. The -s is an imperfective affix.
adit (n.)
"entrance," especially "horizontal mine excavation," c. 1600, from Latin aditus "an approach, an entrance; a going to or drawing near," from past participle stem of adire "to approach," from ad "to" (see ad-) + ire (past participle itus) "to go" (from PIE root *ei- "to go").
adjacence (n.)
"state of lying close or contiguous," c. 1600, from Medieval Latin adjacentia, abstract noun from Latin adiacens "lying at," present participle of adiacere "lie at, border upon, lie near," from ad "to" (see ad-) + iacēre "to lie, rest," related to iacere "to throw; lay ('cast (oneself) down')," from PIE root *ye- "to throw, impel."

Only of things, never of persons or animals. Adjacent, properly, is near but not necessarily in contact; adjoining is so as to touch. Latin adiacentia meant "the neighborhood."

The notion is of setting a date for re-meeting. The meaning "close a meeting" (with or without intention to reconvene) is from early 15c. The sense of "go in a body to another place" (1640s) is colloquial.
The English word has had the -d- since 16c., but the spelling is unetymological, as the compound apparently is not from Latin; Middle French also occasionally has adjourner, but this was rejected in Modern French. Related: Adjourned; adjourning.

late 14c., ajuge, "to make a judicial decision, decide by judicial opinion," from Old French ajugier "to judge, pass judgment on" (Modern French adjuger; the -d- was restored 14c. and English followed suit by 16c.), from Latin adiudicare "grant or award as a judge," from ad "to" (see ad-) + iudicare "to judge," which is related to iudicem "a judge" (see judge (n.)). The sense of "have an opinion" is from c. 1400. Related: Adjudged; adjudging.
adjunct (adj.)
"united with another in office or action," 1590s, from Latin adiunctus "closely connected, joined, united," past participle of adiungere "to join to," usually with a notion of subordination, but this is not etymological (see adjoin). Adjunct professor is attested by 1826, American English.

Originally a term in exorcism (with conjuration); the general sense of "a solemn oath, a charging under the penalty of a curse" is from 17c.
adjustable (adj.)
"capable of being adjusted," 1775, from adjust + -able. Related: Adjustably; adjustability.
adjust (v.)
late 14c., ajusten, "to correct, remedy," from Old French ajuster, ajoster "add; assemble; calibrate, gauge, regulate," from Late Latin adiuxtare "to bring near," from ad "to" (see ad-) + Latin iuxta "next, close by" (from suffixed form of PIE root *yeug- "to join").
In 16c. French corrected to adjuster, but the pedantic effort was rejected and Modern French has ajouter. Influenced in form and sense by folk-etymology, as if from ad- + iustus "just, equitable, fair."
English reborrowed the word by c. 1600 in sense "arrange, settle, compose," from French adjuster "fit (things together) properly, put things in order." The meaning "arrange (something) so as to conform with (a standard or another thing)" is from 1660s. The insurance sense is from 1755 (see adjuster). To adjust to "get used to" is attested by 1924.

French adjudant, earlier ajudant (early 18c.) is from Spanish cognate ayudante. Related: Adjutancy. The adjutant bird is the name given by the English in Bengal to a large type of Indian stork, so called for its "stiff martinet air" [Century Dictionary].
ad lib
also ad lib., 1811 as a musical instruction, shortened from Latin ad libitum "to (one's) pleasure, as much as one likes" (c. 1600), from ad "to" (see ad-) + libitum "pleasure," accusative of libere "to please" (see libido). As a noun from 1825; as a verb by 1915.
administer (v.)
late 14c., aministren, later administren, "to manage as a steward, control or regulate on behalf of others," from Old French aministrer "help, aid, be of service to" (12c., Modern French administrer), and directly from Latin administrare "to help, assist; manage, control, guide, superintend; rule, direct," from ad "to" (see ad-) + ministrare "to serve, attend, wait upon," from minister "inferior, servant, priest's assistant" (see minister (n.)).
The -d- was restored 14c.-16c. in French and after 15c. in English. In reference to punishment, justice, etc., "to dispense, bring into operation" (especially as an officer), from mid-15c.

The estate sense is earliest. For ending, see -er.
administrate (v.)
"manage or direct affairs," 1630s, from Latin administratus, past participle of administrare "manage, control, superintend" (see administer) or else a back-formation from administrator, administration. Related: Administrated; administrating.
administrative (adj.)
"pertaining to administration, having to do with the managing of public affairs," 1731, from Latin administrativus, from administrat-, past-participle stem of administrare "to manage, control, superintend" (see administer). Related: Administratively.

The meaning "a U.S. president's period in office" is recorded by 1796 in the writings of George Washington.
admiral (n.)
c. 1200, amiral, admirail, "Saracen commander or chieftain," from Old French amirail (12c.) "Saracen military commander; any military commander," ultimately from medieval Arabic amir "military commander," probably via Medieval Latin use of the word for "Muslim military leader."
Amiral de la mer "commander of a fleet of ships" is in late 13c. Anglo-French documents. Meaning "highest-ranking naval officer" in English is from early 15c. The extension of the word's meaning from "commander on land" to "commander at sea" likely began in 12c. Sicily with Medieval Latin amiratus and then spread to the continent, but the word also continued to mean "Muslim military commander" in Europe in the Middle Ages. The Arabic word was later Englished as emir.
Also in Old French and Middle English the word was further conformed to familiar patterns as amirauld, amiraunt. The unetymological -d- probably is from influence of Latin ad-mirabilis (see admire). Italian form almiraglio, Spanish almirante are from confusion with Arabic words in al-. As the name of a type of butterfly from 1720, according to OED possibly a corruption of admirable.
admirer (n.)

admiralty (n.)
"naval branch of the English executive," early 15c., admiralte, from Old French amiralte, from amirail (see admiral).

mid-14c., amonesten "remind, urge, exhort, warn, give warning," from Old French amonester "urge, encourage, warn" (12c.), from Vulgar Latin *admonestare, from Latin admonere "bring to mind, remind (of a debt);" also "warn, advise, urge," from ad "to," here probably with frequentative force (see ad-) + monere "to admonish, warn, advise," from PIE *moneie- "to make think of, remind," suffixed (causative) form of root *men- (1) "to think."
The -d- was restored, on the Latin model, in English as in French (Modern French admonester). The ending was influenced by words in -ish (such as astonish, abolish). Related: Admonished; admonishing.

ado (n.)
late 14c., "conflict, fighting; difficulty, trouble," a contraction of at do, literally "to do," a dialectal formation in the Norse-influenced areas of northern England: some Scandinavian languages used at with the infinitive of a verb where Modern English uses to.
From use of the infinitive in much ado ("much to do") and similar phrases, ado came to be regarded as a noun. Compare the sense evolution in to-do and affair (from French infinitive phrase à faire "to do"). The weakened meaning "fuss" is from early 15c. Also used in Middle English for "dealings, traffic," and "sexual intercourse" (both c. 1400).
adobe (n.)
"mudbrick," 1739, American English, from Spanish adobe "unburnt brick dried in the sun," which is said by 19c.

The adjective is the present participle of adolescere "grow up, come to maturity, ripen," from ad "to" (see ad-) + alescere "be nourished," hence, "increase, grow up" (inchoative of alere "to nourish," from a suffixed form of PIE root *al- (2) "to grow, nourish").
Adolesce was a back-formed verb used early 20c. (OED quotes H.G. Wells, G.B. Shaw, Louis MacNeice), but it seems not to have grown.
adolescence (n.)

adoration (n.)
1540s, "act of paying divine honors," from French adoration, from Late Latin adorationem (nominative adoratio) "worship, adoration," noun of action from past-participle stem of adorare "to worship." See adore, the original sense of which is preserved in this word.

Adrian
masc. proper name, from Latin Adrianus, properly Hadrianus, literally "of the Adriatic" (see Adriatic). A name taken by several popes, including the only English pontiff, Nicholas Brakespear (died 1159). The proper name Adrienne, etc., when not a fem. form of this, is a transposition of Ariadne: Adriane is the usual form of Ariadne in Chaucer ("House of Fame," etc.).
Adriatic
sea east of Italy, from Latin Adriaticus, properly Hadriaticus, from town of Atria/Hatria (modern Adria) in Picenum, near Venice, once a seaport but now more than 12 miles inland. The name is perhaps from atra, neuter of atrum "black," hence "the black city;" or else it represents Illyrian adur "water, sea."
adrift (adv.)
"floating at random, at the mercy of currents," 1620s, from a- (1) "on" + drift (n.). Figurative use by 1680s.
adroit (adj.)
1650s, "dexterous," originally "rightly," from French adroit, which by Old French had senses "upright (physically and morally); able, clever, skillful; well-formed, handsome; on the right-hand side; veritable," from adverbial phrase à droit "according to right."
This is from Old French à "to" (see ad-) + droit, dreit "right," from Medieval Latin directum (contracted drictum) "right, justice, law," neuter or accusative of Latin directus "straight," past participle of dirigere "set straight," from dis- "apart" (see dis-) + regere "to direct, to guide, keep straight" (from PIE root *reg- "move in a straight line," with derivatives meaning "to direct in a straight line," thus "to lead, rule"). It expresses prominently the idea of a trained hand. Related: Adroitly; adroitness.
adsorb (v.)
1882, transitive (intransitive use attested from 1919), back-formation from adsorption "condensation of gases on the surfaces of solids" (1882), coined in German from ad- + -sorption, abstracted from absorption and representing Latin sorbere "to suck" (see absorb). Related: Adsorbent; adsorption.
adulate (v.)
"flatter slavishly," 1777, a back-formation from adulation. Related: Adulated; adulating.
adulation (n.)
"servile or insincere praise," late 14c., from Old French adulacion, from Latin adulationem (nominative adulatio) "a fawning; flattery, cringing courtesy," noun of action from past-participle stem of adulari "to flatter, fawn upon."
This is usually said to be from ad "to" (see ad-) + a stem meaning "tail," from a PIE *ul- "the tail" (source also of Sanskrit valah "tail-hair," and Lithuanian valai "horse's tail"). The original notion would be "to wag the tail" like a fawning dog (compare Greek sainein "to wag the tail," also "to flatter;" also see wheedle).
But de Vaan finds phonetic problems with these and concludes the etymology is uncertain, though he proposes a connection with avidus "eager," via *adulo- "who is eager toward something," hence "a flatterer." Adulation may proceed from true blind worship or be insincere, from hope of advantage.
adult (n.)
"adult person," 1650s, from adult (adj.).
adult (adj.)
1530s (but not common until mid-17c.) "grown, mature," from Latin adultus "grown up, mature, adult, ripe," past participle of adolescere "grow up, come to maturity, ripen," from ad "to" (see ad-) + alescere "be nourished," hence, "increase, grow up," inchoative of alere "to nourish," from a suffixed form of PIE root *al- (2) "to grow, nourish."
The meaning "mature in attitude or outlook" is from 1929. As a euphemism for "pornographic," it dates to 1958 and does no honor to the word. In the old British film-rating system, A indicated "suitable for exhibit to adult audiences," and thus, implicitly, unsuitable for children (1914).
adulteration (n.)
c. 1500, "act of adulterating; state of being debased by mixture with something else," generally of inferior quality, from Latin adulterationem (nominative adulteratio) "an adulteration, sophistication," noun of action from past-participle stem of adulterare "corrupt, falsify; debauch; commit adultery," from ad "to" (see ad-) + alterare "to alter" (see alter), though Watkins explains it as ad alterum "(approaching) another (unlawfully)." Meaning "a result of adulterating" is from 1650s.
