TNT Look up TNT at

to (prep.) Look up to at
Old English to "in the direction of, for the purpose of, furthermore," from West Germanic *to (source also of Old Saxon and Old Frisian to, Dutch toe, Old High German zuo, German zu "to"), from PIE pronominal base *do- "to, toward, upward" (source also of Latin donec "as long as," Old Church Slavonic do "as far as, to," Greek suffix -de "to, toward," Old Irish do, Lithuanian da-), from demonstrative *de-. Not found in Scandinavian, where the equivalent of till (prep.) is used.

The nearly universal use of to with infinitives (to sleep, to dream, etc.) arose in Middle English out of the Old English dative use of to, and it helped drive out the Old English inflectional endings (though in this use to itself is a mere sign, without meaning).

Commonly used as a prefix in Middle English (to-hear "listen to," etc.), but few of these survive (to-do, together, and time references such as today, tonight, tomorrow -- Chaucer also has to-yeere). To and fro "side to side" is attested from mid-14c. Phrase what's it to you "how does that concern you?" (1819) is a modern form of an old question:
Huæd is ðec ðæs?
[John xxi:22, in Lindisfarne Gospel, c.950]
to- Look up to- at
particle expressing separation, putting asunder, from West Germanic *ti- (source also of Old Frisian ti-, Old High German zi-, German zer-), from Proto-Germanic *tiz-, cognate with Latin-derived dis-. According to OED, some 125 compound verbs with this element are recorded in Old English; their number declined rapidly in Middle English and disappeared by c. 1500 except as conscious archaisms (such as to-shiver "break to pieces;" all to-brast).
to-do (n.) Look up to-do at
1570s, from the verb phrase to do, from Old English to don "proper or necessary to be done" (see to + do). Meaning "disturbance, fuss" is first recorded 1827. Similar formation in French affaire, from à "to" + faire "do."
toad (n.) Look up toad at
c. 1300, from late Old English tadige, tadie, of unknown origin and according to OED with no known cognates outside English. Applied to loathsome persons from 1560s. Toad-strangler "heavy rain" is from 1919, U.S. Southern dialectal.
toadstone (n.) Look up toadstone at
"stone or stone-like object, supposedly magical (with healing or protective power) and found in the heads of certain toads," 1550s, from toad + stone (n.). Translating Greek batrakhites, Medieval Latin bufonites; compare also French crapaudine (13c.), German krötenstein.
The Crapadine or Toadstone, we speak of before, you shall prove to be a true one, if the Toad lift himself so up against it, when it is shew'd or held to him, as if he would come at it, and leap to catch it away: he doth so much envy that Man should have that stone. ["Eighteen Books of the Secrets of Art & Nature," 1661]
toadstool (n.) Look up toadstool at
late 14c., apparently just what it looks like: a fanciful name from Middle English tadde "toad" (see toad) + stole "stool" (see stool). Toads themselves were regarded as highly poisonous, and this word is "popularly restricted to poisonous or inedible fungi, as distinct from edible "mushrooms" [OED]. Compare toad-cheese, a poisonous fungi; toad's meat (1886), a "rustic" term for toadstool.
toady (n.) Look up toady at
"servile parasite," 1826, apparently shortened from toad-eater "fawning flatterer" (1742), originally (1620s) "the assistant of a charlatan," who ate a toad (believed to be poisonous) to enable his master to display his skill in expelling the poison. The verb is recorded from 1827. Related: Toadied; toadying.
toast (n.2) Look up toast at
"piece of bread browned by fire or dry heat," early 15c., from toast (v.1); originally as something added to wine, ale, etc. From 17c. in the modern sense as something eaten on its own with a spread. Slang meaning "a goner, person or thing already doomed or destroyed" is recorded by 1987, perhaps from notion of computer circuits being "fried," and with unconscious echoes of earlier figurative phrase to be had on toast (1886) "to be served up for eating."
toast (v.2) Look up toast at
"to propose or drink a toast," 1700, from toast (n.1). This probably is the source of the Jamaican and African-American vernacular word meaning "extemporaneous narrative poem or rap" (1962). Related: Toasted; toasting.
toast (n.1) Look up toast at
"a call to drink to someone's health," 1700 (but said by Steele, 1709, to date to the reign of Charles II), originally referring to the beautiful or popular woman whose health is proposed and drunk. The custom apparently has its origin in the use of spiced toast (n.2) to flavor drink, the lady being regarded as figuratively adding piquancy to the wine in which her health was drunk. Steele's story ["Tatler," No. 24] is that an (unnamed) beauty of the day was taking the cold waters at Bath, when a gentleman dipped his cup in the water and drank it to her health; another in his company wittily (or drunkenly) replied that, while he did not care for the drink, he would gladly enjoy the toast. Meaning "one whose health is proposed and drunk to" is from 1746. Toast-master attested from 1749.

tobacco (n.) Look up tobacco at
1580s, from Spanish tabaco, in part from an Arawakan language of the Caribbean (probably Taino), said to mean "a roll of tobacco leaves" (according to Las Casas, 1552) or "a kind of pipe for smoking tobacco" (according to Oviedo, 1535). Scholars of Caribbean languages lean toward Las Casas' explanation. But Spanish tabaco (also Italian tabacco) was a name of medicinal herbs from early 15c., said to be from Arabic tabbaq, attested since 9c. as the name of various herbs but they bear little resemblance to tobacco, and the name similarity might be coincidence. The West Indian island of Tobago was said to have been named by Columbus in 1498 from Haitian tambaku "pipe," in reference to the native custom of smoking dried tobacco leaves [Room].

Cultivation in France began 1556 with an importation of seed by Andre Thevet; introduced in Spain 1558 by Francisco Fernandes. Tobacco Road as a mythical place representative of rural Southern U.S. poverty is from the title of Erskine Caldwell's 1932 novel. Early German and Portuguese accounts of Brazil also record another name for tobacco, bittin or betum, evidently a native word in South America, which made its way into 17c. Spanish, French, and English as petun, petumin, etc., and which is preserved in petunia and butun, the Breton word for "tobacco."
Many haue giuen it [tobacco] the name, Petum, whiche is in deede the proper name of the Hearbe, as they whiche haue traueiled that countrey can tell. [John Frampton, translation of Nicolás Monardes' "Joyful Newes Oute of the Newe Founde Worlde," 1577]

toga (n.) Look up toga at
c. 1600, from Latin toga "cloak or mantle," from PIE *tog-a- "covering," suffixed form of root *(s)teg- "to cover." The outer garment of a Roman citizen in time of peace.
The toga as the Roman national dress was allowed to be worn by free citizens only. A stranger not in full possession of the rights of a Roman citizen could not venture to appear in it. Even banished Romans were in imperial times precluded from wearing it. The appearance in public in a foreign dress was considered as contempt of the majesty of the Roman people. Even boys appeared in the toga, called, owing to the purple edge attached to it (a custom adopted from the Etruscans) toga praetexta. On completing his sixteenth, afterward his fifteenth, year (tirocinium fori), the boy exchanged the toga praetexta for the toga virilis, pura, or libera--a white cloak without the purple edge. Roman ladies (for these also wore the toga) abandoned the purple edge on being married. [Guhl & Koner, "The Life of the Greeks and Romans," transl. Francis Hueffer, 1876]
Breeches, like the word for them (Latin bracae) were alien to the Romans, being the dress of Persians, Germans, and Gauls, so that bracatus "wearing breeches" was a term in Roman geography meaning "north of the Alps."

Subsequent sense evolution in English (mostly following French uses) is to "act or process of dressing," especially the dressing and powdering of the hair (1680s); then "a dressing room" (1819), especially one with a lavatory attached; then "lavatory or porcelain plumbing fixture" (1895), an American euphemistic use.
