Attic (adj.)
1590s, "pertaining to Attica" (q.v.), the region around Athens, from Latin Atticus "Athenian," from Greek Attikos "Athenian, of Attica."

The word is attested from 1560s as an architectural term for a type of column base.
attic (n.)
"top story under the roof of a house," by 1807, shortened from attic story (1724). Attic in classical architecture meant "a small, square decorative column of the type often used in a low story above a building's main facade," a feature associated with the region around Athens (see Attic). The word then was applied by architects to "a low decorative facade above the main story of a building" (1690s in English), and it then came to mean the space enclosed by such a structure. The modern use is via French attique. "An attic is upright, a garret is in a sloping roof" [Weekley].
Attica
"region around Athens," traditionally explained as from Greek Attikos (Latin Atticus) "of Athens" (see Athens), which is supported by Beekes. An alternative guess is that it is ultimately from Greek aktē "shore, maritime place," also "raised place."

Originally 17c. a technical term in art; later generalized to "a posture of the body supposed to imply some mental state" (1725). The sense of "a settled behavior reflecting feeling or opinion" is by 1837. The meaning "habitual mode of regarding" is short for attitude of mind (1757). Connotations of "antagonistic and uncooperative" developed by 1962 in slang.

attitudinize (v.)
1784, "strike (physical) attitudes, pose affectedly, gesticulate;" see attitude + -ize. Of mental attitudes from 1864. Related: Attitudinized; attitudinizing. In 18c. English had also attitudinarian "one who affects attitudes" (1756).

In feudal law, "to transfer homage or allegiance to another lord."
attorney (n.)
early 14c. (mid-13c. in Anglo-Latin), "one appointed by another to act in his place," from Old French atorné "(one) appointed," past participle of aturner "to decree, assign, appoint," from atorner "to assign," literally "to turn to" (see attorn). The sense is of "one appointed to represent another's interests."
In English law, a private attorney (attorney in fact) was one appointed to act for another in business or legal affairs (usually for pay); an attorney at law or public attorney was a qualified legal agent in the courts of Common Law who prepared the cases for a barrister, who pleaded them (the equivalent of a solicitor in Chancery). So much a term of contempt in England that it was abolished by the Judicature Act of 1873 and merged with solicitor.
In U.S., barrister is not used and the general designation became properly attorney and counselor at law; when presenting a case in court, simply counselor. The double -t- is a mistaken 15c. attempt to restore a non-existent Latin original, perhaps by influence of legal Latin form attornare.

The more popular theory is that it is from Latin avis "bird," because the flights, singing, and feeding of birds were important objects of divination (compare auspex). In that case, the second element would be from garrire "to talk." Related: Augural; augurial.
augury (n.)
late 14c., "divination from the flight of birds," from Old French augure, augurie "divination, soothsaying, sorcery, enchantment," or directly from Latin augurium "divination, the observation and interpretation of omens" (see augur (n.)). The sense of "omen, portent, indication, that which forebodes" is from 1610s. Often in plural, auguries.
august (adj.)
"inspiring reverence and admiration, solemnly grand," 1660s, from Latin augustus "venerable, majestic, magnificent, noble," perhaps originally "consecrated by the augurs, with favorable auguries" (see augur (n.)); or else [de Vaan] "that which is increased" (see augment).
August
eighth month, late 11c., from Latin Augustus (mensis), sixth month of the later Roman calendar, renamed from Sextilis (literally "sixth") in 8 B.C.E. to honor emperor Augustus Caesar, literally "Venerable Caesar" (see august (adj.), and compare Augustus). One of two months given new names to honor Roman leaders (July being the other), the Romans also gave new imperial names to September (Germanicus) and October (Domitian) but these did not stick.
In England, the name replaced native Weodmonað "weed month." Traditionally the first month of autumn in Great Britain, the last of summer in the U.S.
Augusta
fem. proper name, Latin fem. of Augustus (q.v.).
Augustan (adj.)
1640s, from Latin Augustanus, "pertaining to Augustus (Caesar)," whose reign (31 B.C.E.-14 C.E.) was connected with "the palmy period of Latin literature" [OED]; hence, "period of purity and refinement in any national literature" (1712); in French, the reign of Louis XIV; in English, that of Queen Anne.
Augustine (adj.)
c. 1400 in reference to members of the religious order named for St. Augustine the Great (354-430), bishop of Hippo. The name is Latin Augustinus, from augustus "venerable, majestic, magnificent, noble" (see august (adj.)) + name-forming element -inus (see -ine (1)). Related: Augustinian.
Augustus
masc. proper name, from Latin augustus "venerable" (see august (adj.)). The name originally was a cognomen applied to Gaius Julius Caesar Octavianus as emperor, with a sense something like "his majesty."
auk (n.)
type of large, colonial diving bird, 1670s, a Northern England name, from a Scandinavian source such as Old Norse alka, probably originally imitative of a water-bird cry (compare Latin olor "swan," Greek elea "marsh bird"). Originally and properly the great auk, which once abounded on North Atlantic coasts; hunted for food, bait, and its down, the species became extinct c. 1850.
auld (adj.)
variant of old that more accurately preserves the Anglo-Saxon vowel. Surviving in northern English and Scottish; after late 14c. it was distinctly Scottish. A child wise or canny beyond its years was auld-farrand; Auld wives' tongues was a name for the aspen, because its leaves "seldom cease wagging."
au naturel (adj.)
1817, "uncooked," French, literally "naturally, in the natural state." Originally in English a term in French recipes, it was used euphemistically in English for "undressed" by 1860, perhaps via its use in French in the visual arts. See au + natural (adj.).
