c. 1300, "shield," diminutive of late Old English targe, from Old French targe "light shield" (12c.), from Frankish *targa "shield," from Proto-Germanic *targ- (source also of Old High German zarga "edging, border," German zarge "border, edge, frame," Old English targe, Old Norse targa "shield, buckler"), perhaps originally "edge of a shield." Meaning "round object to be aimed at in shooting" first recorded 1757, originally in archery, perhaps suggested by the concentric circles in both. Target-practice is from 1801. Target audience is by 1951; early reference is to Cold War psychological warfare.
1590s, "arithmetical table," also "official list of customs duties on imports or exports; law regulating import duties," from Italian tariffa "tariff, price, assessment," Medieval Latin tarifa "list of prices, book of rates," from Arabic ta'rif "information, notification, a making known; inventory of fees to be paid," verbal noun from arafa "he made known, he taught." Sense of "classified list of charges made in a business" is recorded from 1757. The U.S. Tariff of Abominations was passed in 1828.
late 14c., mid-13c. in Anglo-Latin, from Old Norse tjörn "small mountain lake without visible tributaries," from Proto-Germanic *terno, perhaps originally "water hole" [Barnhart]. A dialectal word popularized by the Lake poets.
mid-15c. ternishen, "become tarnished; discolor," from Old French terniss-, present-participle stem of ternir "dull the luster or brightness of, make dim" (15c.), probably from terne (adj.) "dull, dark," which according to Diez is from a Germanic source cognate with Old High German tarnjan "to conceal, hide," Old English dyrnan "to hide, darken," from Proto-Germanic *darnjaz (see dern), but there are difficulties of form, sense, and date. Figurative sense is from 1690s. Related: Tarnished; tarnishing.
tropical food plant, 1769, from Polynesian (Tahitian or Maori) taro. Compare Hawaiian kalo.
1610s, name of an old card game of Italy, Austria, etc., played originally with a 78-card deck that includes four suits, four face-cards each, plus the tarot cards as trumps; from Old Italian tarocchi (plural); see tarot.
1590s, from French tarot (16c.), from Old Italian tarocchi (singular tarocco), a word of unknown origin, perhaps from Arabic taraha "he rejected, put aside." Originally an everyday game deck in much of Europe (though not in Britain), their occult and fortune-telling use seems to date from late 18c. and became popular in England 20c. Tarot games seem to have originated among aristocrats in northern Italy in early 15c. By early 16c. tarocchi had emerged in Italian as the name of the special cards, and by extension the whole pack; whence the French word, German Tarock, etc. The tarots are thus, strictly speaking, the 22 figured cards added to the 56-card suits pack.
