They were regarded by the ancients as air ducts because the arteries do not contain blood after death, and 14c.-16c. artery in English also could mean "trachea, windpipe." Medieval writers, based on Galen, generally took them as a separate blood system for the "vital spirits." The word is used in reference to artery-like systems of major rivers from 1805; of railways from 1844.
artesian (adj.)
1830, literally "pertaining to Artois," originally in artesian well, from French puits artésien "wells of Artois," the French province where such wells were first bored 18c. by French engineer Bernard Forest de Bélidor (1698-1761). The place name is from Old French Arteis, from Atrebates, a tribe that lived in northwestern Gallia (compare Arras). In a true artesian well the water rises naturally to the surface, but this depends on peculiarities of local geology; in the U.S. the term was used of any deep-bored well, even if the water must be pumped to the surface.
artesian well (n.)

1610s, "learned, well-versed in the (liberal) arts," also "characterized by technical skill, artistic," from art (n.) + -ful.

arthritis (n.)
"inflammation of a joint," 1540s, from medical Latin arthritis, from Greek (nosos) arthritis "(disease) of the joints," from arthritis, fem. of arthrites (adj.) "pertaining to joints" (Greek nosos is a fem. noun), from arthron "a joint," from PIE root *ar- "to fit together." The older noun form was arthetica (late 14c.).

artichoke (n.)
"thistle-like plant," also "the head of the flower stem, used as food," 1530s, from articiocco, Northern Italian variant of Italian arcicioffo, from Old Spanish alcarchofa, from Arabic al-hursufa "artichoke." The Northern Italian variation probably is from influence of ciocco "stump."

Folk etymology has twisted the word in English; the ending is probably influenced by choke, and early forms of the word in English include archecokk, hortichock, artychough, hartichoake, reflecting various folk-etymologies from French and Latin words. The plant is native to the Mediterranean and was known to the Romans and Greeks (see cardoon); the modern, improved variant seems to have been bred in North Africa (hence the new, Arabic name) and reached Italy by mid-15c. It was introduced into England in the reign of Henry VIII. French artichaut (16c.), German Artischocke (16c.) are from Italian, and from the same source come Russian artishoku, Polish karczock.
article (n.)

Meaning "literary composition in a journal, etc." (independent and on a specific topic, but part of a larger work) is first recorded 1712. The older sense is preserved in Articles of War "military regulations" (1716), Articles of Confederation (U.S. history), etc. Extended meaning "piece of property, material thing, commodity" (clothing, etc.) first attested 1796, originally in rogue's cant. Grammatical sense of "word used attributively, to limit the application of a noun to one individual or set of individuals" is from 1530s, from this sense in Latin articulus, translating Greek arthron.
articular (adj.)
"involving joints," early 15c., from Latin articularis "pertaining to the joints," from articulus "a joint" (see article).
articulate (v.)

Generalized sense of "express in words" is from 1690s. In a physical sense, "to join, to attach by joints," it is attested from 1610s. Earlier sense "to set forth in articles" (1560s) now is obsolete or nearly so. Related: Articulated; articulating.

1580s in the speech sense, "divided into distinct parts," hence "clear, distinct" (1570s as "set forth in articles"), from Latin articulatus "separated into joints" (see articulate (v.)).

Meaning "the uttering of articulate sounds" is from 1610s.
artifact (n.)
1821, artefact, "artificial production, anything made or modified by human art," from Italian artefatto, from Latin arte "by skill" (ablative of ars "art;" see art (n.)) + factum "thing made," from facere "to make, do" (from PIE root *dhe- "to set, put"). The word is attested in German from 1791. The English spelling with -i- is attested by 1884, by influence of the Latin stem (as in artifice). Originally a word in anatomy to denote artificial conditions caused by operation, etc.; archaeological application in English dates from 1885 (in German from 1875).
artifactual (adj.)
also artefactual, "not natural, of the nature of an artifact," 1914, from artifact + -ual as in factual. Earlier artefact was used as an adjective (1909).

Earliest use in English is in the phrase artificial day "part of the day from sunrise to sunset" (as opposed to the natural day of 24 hours). Meaning "made by man, contrived by human skill and labor" is from early 15c. The word was applied from 16c. to anything made in imitation of, or as a substitute for, what is natural, whether real (light, tears) or not (teeth, flowers). Meaning "fictitious, assumed, not genuine" is from 1640s; that of "full of affectation, insincere" is from 1590s. Artificial insemination dates from 1894.

But some would connect it to Latin articulum "joint," others to Latin apere "to attach, join," and still others to Old French atillier "to equip," altered by influence of arte.

Originally any engine for discharging missiles (catapults, slings, bows, etc.); modern restriction to "ordnance, large guns" is from 16c. Technically, "all firearms discharged from carriages," as opposed to small arms, discharged by hand. As a branch of the army, from 1786.
artisan (adj.)
1859, from artisan (n.) or from adjectival use of the noun in French.

Barnhart reports Middle French artisan, often given as the direct source of the English word, is attested too late to be so.
artist (n.)
1580s, "one who cultivates one of the fine arts," from Middle French artiste (14c.), from Italian artista, from Medieval Latin artista, from Latin ars (see art (n.)).

Originally especially of the arts presided over by the Muses (history, poetry, comedy, tragedy, music, dancing, astronomy), but also used 17c. for "one skilled in any art or craft" (including professors, surgeons, craftsmen, cooks).

artiste (n.)
"one skillful in some art not considered one of the fine arts," 1819 in English, from 1804 as a French word, from French artiste; a reborrowing of artist, at first in a foreign context, later used to fill the gap after the sense of artist had become limited toward the visual arts and especially painting.
Artiste: an admirable word (albeit somewhat Frenchified) of late applied, with nice discrimination, to every species of exhibitor, from a rope-dancer down to a mere painter or sculptor. On looking into little Entick (my great authority in these matters), I find we have already the word artist; but with stupid English perversity, we have hitherto used that in a much more restricted sense than its newly-imported rival, which it is becoming the excellent fashion to adopt. ["Paul Pry's Journal of a Residence at Little-Pedlington," Philadelphia, 1836]
artistic (adj.)
