'Tis: abbreviation of it is, first recorded c.1450.
-teen: combining form meaning "ten more than," from O.E. -tene, -tiene, from P.Gmc. *tekhuniz (cf. O.S. -tein, Du. -tien, O.H.G. -zehan, Ger. -zehn, Goth. -taihun), an inflected form of the root of ten; cognate with L. -decim (cf. It. -dici, Sp. -ce, Fr. -ze). The combining form of ordinal numbers, -teenth, developed from O.E. -teoða, -teoðe (W.Saxon), teogoða (Anglian) "tenth."
-th: suffix forming nouns from verbs (depth, strength, truth, etc.), from O.E. -ðu, -ð, from PIE *-ita (cf. Skt. -tati-, Gk. -tet-, L. -tati-). The suffix forming ordinal numbers (fourth, tenth, etc.) is O.E. -ða, from PIE *-tos (cf. Skt. thah, Gk. -tos, L. -tus).
-tion: suffix forming nouns from verbs, from L. -tionem, accusative of noun suffix -tio (gen. -tionis) forming nouns of condition and action (the -t- is the Latin pp. stem).
-tomy: comb. form meaning "a cutting," from Gk. -tomia "a cutting of," from tome "a cutting, section" (see tome).
-trix: fem. agential suffix, from L., corresponding to masc. -tor.
-tron: as a suffix in new compounds formed in physics, 1939, abstracted from electron (Gk. -tron was an instrumentive suffix).
-trope: comb. form meaning "that which turns," from Gk. tropos (see trope).
-trophy: comb. form meaning "food, nourishment," from Gk. trophe "food, nourishment," related to trephein "to make solid, congeal, thicken."
-tude: Latinate suffix forming abstract nouns from adjectives and participles (corresponding to native -ness), from Fr. -tude, from L. -tudo (gen. -tudinis). As a word in its own right, teenager slang shortening of attitude, it dates from 1970s.
-ty (1): suffix representing "ten" in cardinal numbers (sixty, seventy, etc.), from O.E. -tig, from a Gmc. root (cf. Du. -tig, O.Fris. -tich, O.N. -tigr, O.H.G. -zig, -zug, Ger. -zig) that existed as a distinct word in Gothic tigjus, O.N. tigir "tens, decades." English, like many other Germanic languages, retains traces of a base-12 number system. The most obvious instance is eleven and twelve which ought to be the first two numbers of the "teens" series. Their Old English forms, enleofan and twel(eo)f(an), are more transparent: "leave one" and "leave two." Old English also had hund endleofantig for "110" and hund twelftig for "120." One hundred was hund teantig. The -tig formation ran through 12 cycles, and could have bequeathed us numbers *eleventy ("110") and *twelfty ("120") had it endured, but already during the O.E. period it was being obscured. O.N. used hundrað for "120" and þusend for "1,200." Tvauhundrað was "240" and þriuhundrað was "360." Older Germanic legal texts distinguished a "common hundred" (100) from a "great hundred" (120). This duodecimal system, according to one authority, is "perhaps due to contact with Babylonia."
-ty (2): suffix used in forming abstract nouns from adjectives (safety, surety, etc.), M.E. -te, from O.Fr. -te, from L. -tatem (-tas, gen. -tatis), cognate with Gk. -tes, Skt. -tati-.

Tabasco: proprietary name of a type of hot sauce, 1876, (the sauce so called from 1652, originally Tavasco), named for state in Mexico, perhaps because the pepper sauce was first encountered there by U.S. and European travelers. The trademark (by Edward Avery McIlhenny) claims use from c.1870.

Tabby cat, one with a striped coat, is attested from 1695; shortened form tabby first attested 1774.

Tafel), both from L. tabula "a board, plank, table," originally "small flat slab or piece" usually for inscriptions or for games, of uncertain origin, related to Umbrian tafle "on the board." The sense of "piece of furniture with the flat top and legs" first recorded c.1300 (the usual L. word for this was mensa; O.E. writers used bord). The meaning "arrangement of numbers or other figures for convenience" is recorded from c.1386 (e.g. table of contents, 1460). Tablecloth is from 1467; tablespoon is 1763; tableware first recorded 1852. Fig. phrase turn the tables (1634) is from backgammon (in O.E. and M.E. the game was called tables).

tabloid: 1884, "small tablet of medicine," trademark name (by Burroughs, Wellcome and Co.) for compressed or concentrated chemicals and drugs, formed from tablet + Gk.-derived suffix -oid, from oeides "like." By 1898, it was being used figuratively to mean a compressed form or dose of anything, hence tabloid journalism (1901), and newspapers that typified it (1918), so called for having short, condensed news articles and/or for being small in size.
taboo: 1777 (in Cook's "A Voyage to the Pacific Ocean"), "consecrated, inviolable, forbidden, unclean or cursed," explained in some Englishsources as being from Tongan (Polynesian language of the island of Tonga) ta-bu "sacred," from ta "mark" + bu "especially." But this may be folk etymology, as linguists in the Pacific have reconstructed an irreducable Proto-Polynesian *tapu, from Proto-Oceanic *tabu "sacred, forbidden" (cf. Hawaiian kapu "taboo, prohibition, sacred, holy, consecrated;" Tahitian tapu "restriction, sacred;" Maori tapu "be under ritual restriction, prohibited").

Verb sense of "to attach as a supplement" (with suggestion of hasty or arbitrary proceeding) is attested from 1683. The meaning "rope to hold the corner of a sail in place" is first recorded 1481; hence the verb meaning "sail into the wind," first recorded 1557, which lead to the fig. sense of "course or line of conduct or action" (1675).
