tilde (n.): 1864, from Spanish, metathesis of Catalan title, from Latin titulus "inscription, heading" (see title (n.)).
tile (n.): Old English tigele "roofing shingle," from West Germanic *tegala (cf. Old High German ziagal, German ziegel, Dutch tegel, Old Norse tigl), a borrowing from Latin tegula "tile" (cf. Italian tegola, French tuile), from tegere "roof, to cover" (see stegosaurus). Also used in Old English and early Middle English for "brick," before that word came into use. The verb meaning "to cover with tiles" is recorded from late 14c.
till (prep.): "until," Old English til (Northumbrian), from Old Norse til "to, until," from Proto-Germanic *tilan (cf. Danish til, Old Frisian til "to, till," Gothic tils "convenient," German Ziel "limit, end, goal"). A common preposition in Scandinavian, probably originally the accusative case of a noun now lost except for Icelandic tili "scope," the noun used to express aim, direction, purpose (e.g. aldrtili "death," literally "end of life"). Also cf. German Ziel "end, limit, point aimed at, goal," and compare till (v.).
till (v.): "cultivate (land)" (early 13c.), "plow" (late 14c.), from Old English tilian "tend, work at, get by labor," originally "strive after," related to till "fixed point, goal," and til "good, suitable," from Proto-Germanic *tilojanan (cf. Old Frisian tilia "to get, cultivate," Old Saxon tilian "to obtain," Middle Dutch, Dutch telen "to breed, raise, cultivate, cause," Old High German zilon "to strive," German zielen "to aim, strive"), from source of till (prep.). Related: Tilled; tilling.
till (n.): "cashbox," mid-15c., from Anglo-French tylle "compartment," Old French tille "compartment, shelter on a ship," probably from Old Norse þilja "plank, floorboard," from Proto-Germanic *theljon. The other theory is that the word is from Middle English tillen "to draw," from Old English -tyllan (see toll (v.)), with a sense evolution as in drawer (see draw).
tillage (n.): late 15c., from till (v.) + -age.
tiller (n.): mid-14c., "stock of a crossbow," from Old French telier "stock of a crossbow" (c.1200), originally "weaver's beam," from Medieval Latin telarium, from Latin tela "web, loom," from PIE *teks-la-, from root *teks- "to weave" (see texture). Meaning "bar to turn the rudder of a boat" first recorded 1620s.
tilt (v.): Old English *tyltan "to be unsteady," from tealt "unsteady," from Proto-Germanic *taltaz (cf. Old Norse tyllast "to trip," Swedish tulta "to waddle," Norwegian tylta "to walk on tip-toe," Middle Dutch touteren "to swing"). Meaning "to cause to lean, tip, slope" (1590s) is from sense of "push or fall over." Intransitive sense first recorded 1620s. Related: Tilted; tilting.
tilt (n.1): "a joust, a combat," 1510s, perhaps from tilt (v.) on the notion of "to lean" into an attack, but the word originally seems to have been the name of the barrier which separated the combatants, which suggests connection with tilt in an earlier meaning "covering of coarse cloth, an awning" (mid-15c.), which is probably from tilt (v.), but perhaps related to or influenced by tent, or it may be from a Germanic source akin to Old English beteldan "to cover." The verb is recorded from 1590s. Hence, also full tilt (c.1600).
tilt (n.2): "condition of being tilted," 1837, from tilt (v.).
tilth (n.): "labor, work" (especially in agriculture), Old English tilþ, from tilian "to till" (see till (v.)) + -th.
timber (n.): Old English timber "building, structure," later "building material, trees suitable for building," and "wood in general," from Proto-Germanic *temran (cf. Old Frisian timber "wood, building," Old High German zimbar "timber, wooden dwelling, room," Old Norse timbr "timber," German Zimmer "room"), from PIE *demrom-, from root *dem-/*dom- "build" (source of Greek domos, Latin domus; see domestic (adj.)).

The related Old English verb timbran, timbrian was the chief word for "to build" (cf. Dutch timmeren, German zimmern). As a call of warning when a cut tree is about to fall, it is attested from 1912 in Canadian English. Timbers in the nautical slang sense (see shiver (n.)) is from the specialized meaning "pieces of wood composing the frames of a ship's hull" (1748).
timberline (n.): 1867, from timber + line (n.).
timbre (n.): "characteristic quality of a musical sound," 1849, from French timbre "quality of a sound," earlier "sound of a bell," from Old French, "bell without a clapper," originally "drum," probably via Medieval Greek *timbanon, from Greek tympanon "kettledrum" (see tympanum). Timbre was used in Old French (13c.) and Middle English (14c.) to render Latin tympanum in Ps. 150.
timbrel (n.): "percussive Middle Eastern instrument," c.1500, diminutive of timbre (q.v.) in its older French sense of "drum." Used in Bible translations, chiefly to render Hebrew taph, cognate with Arabic duff "drum," of imitative origin.

time (n.): Old English tima "limited space of time," from Proto-Germanic *timon "time" (cf. Old Norse timi "time, proper time," Swedish timme "an hour"), from PIE *di-mon-, from root *da- "cut up, divide" (see tide).

Abstract sense of "time as an indefinite continuous duration" is recorded from late 14c. Personified since at least 1509 as an aged bald man (but with a forelock) carrying a scythe and an hour-glass. In English, a single word encompasses time as "extent" and "point" (French temps/fois, German zeit/mal) as well as "hour" (e.g. "what time is it?" cf. French heure, German Uhr). Extended senses such as "occasion," "the right time," "leisure," or times (v.) "multiplied by" developed in Old and Middle English, probably as a natural outgrowth of phrases like, "He commends her a hundred times to God" (Old French La comande a Deu cent foiz).

Previous to 1883 the methods of measuring time in the United States were so varied and so numerous as to be ludicrous. There were 50 different standards used in the United States, and on one road between New York and Boston, whose actual difference is 12 minutes, there were three distinct standards of time. Even small towns had two different standards one known as "town" or local time and the other "railroad" time.

... At noon on November 18, 1883, there was a general resetting of watches and clocks all over the United States and Canada, and the four great time zones, one hour apart, into which the country was divided came into being. So smoothly did the plan work that the general readjustment was accomplished without great difficulty and it has worked satisfactorily ever since. ["Railroad Trainman," 1909]
