- Old English ðorp "village, hamlet, farm, estate," reinforced by Old Norse ðorp, both from Proto-Germanic *thurpa- (source also of Old Frisian thorp, Frisian terp, Middle Dutch, Dutch dorp, German dorf "village," Gothic þaurp "estate, land, field"), probably from PIE root *treb- "dwelling" (see tavern). Preserved in place names ending in -thorp, -thrup.

- thou (pron.)
- 2nd nominative singular personal pronoun, Old English þu, from Proto-Germanic *thu (source also of Old Frisian thu, Middle Dutch and Middle Low German du, Old High German and German du, Old Norse þu, Gothic þu), from PIE *tu-, second person singular pronoun (source also of Latin tu, Irish tu, Welsh ti, Greek su, Lithuanian tu, Old Church Slavonic ty, Sanskrit twa-m).
Superseded in Middle English by plural form you (from a different root), but retained in certain dialects (e.g. early Quakers). The plural at first was used in addressing superior individuals, later also (to err on the side of propriety) strangers, and ultimately all equals. By c. 1450 the use of thou to address inferiors gave it a tinge of insult unless addressed by parents to children, or intimates to one another. Hence the verb meaning "to use 'thou' to a person" (mid-15c.).
Avaunt, caitiff, dost thou thou me! I am come of good kin, I tell thee!
["Hickscorner," c. 1530]
A brief history of the second person pronoun in English can be found here.
- though (adv., conj.)
- c. 1200, from Old English þeah "though, although, even if, however, nevertheless, although, still, yet;" and in part from Old Norse þo "though," both from Proto-Germanic *thaukh (source also of Gothic þauh, Old Frisian thach, Middle Dutch, Dutch doch, Old High German doh, German doch), from PIE demonstrative pronoun *to- (see that). The evolution of the terminal sound did not follow laugh, tough, etc., though a tendency to end the word in "f" existed c. 1300-1750 and persists in dialects.
- thought (n.)
- Old English þoht, geþoht "process of thinking, a thought; compassion," from stem of þencan "to conceive of in the mind, consider" (see think). Cognate with the second element in German Gedächtnis "memory," Andacht "attention, devotion," Bedacht "consideration, deliberation." Second thought "later consideration" is recorded from 1640s.
Bammesberger ("English Etymology") explains that in Germanic -kt- generally shifted to -ht-, and a nasal before -ht- was lost. Proto-Germanic *thankija- added a suffix -t in the past tense. By the first pattern the Germanic form was *thanht-, by the second the Old English was þoht.

Related to words in Balto-Slavic (Lithuanian tukstantis, Old Church Slavonic tysashta, Polish tysiąc, Russian tysiacha, Czech tisic), and probably ultimately a compound with indefinite meaning "great multitude, several hundred," literally "swollen-hundred," with first element from PIE root *teue- (2) "to swell" (see thigh).
Used to translate Greek khilias, Latin mille, hence the refinement into the precise modern meaning. There was no general Indo-European word for "thousand." Slang shortening thou first recorded 1867. Thousand island dressing (1916) presumably is named for the region of New York on the St. Lawrence River.
- thousandth (adj.)

Meaning "spiral ridge of a screw" is from 1670s. Threads, slang for "clothes" is 1926, American English.
The silk line, as spun by the worm, is about the 5000th part of an inch thick; but a spider's line is perhaps six times finer, or only the 30,000th part of an inch in diameter, insomuch, that a single pound of this attenuated substance might be sufficient to encompass our globe. [John Leslie, "Elements of Natural Philosophy," Edinburgh, 1823]

- Three Rs (n.)
- 1824; said to have been given as a toast by Sir William Curtis (1752-1829), a beloved lord mayor of London in the 1820s, who seems to have been a figure of fun to whom many mangled phrases were attributed. Among the toasts he is alleged to have given at public dinners were "The Female Ladies of London;" "The three C's--Cox, King, and Curtis;" and "The three R's--Reading, Writing, and Rithmetic."
It has been very much the fashion amongst a class of persons to attribute to Sir W. C. ... a vulgarity and ignorance of speech which are by no means consistent with his character and conduct. The worthy and hospitable baronet has a rapid mode of speech, but it is always correct ; and although some eccentricities are mixed up in his composition, he is highly honourable, and has been a very useful member of society, particularly to his London constituents. ["The Mirror," Jan. 29, 1825]
After listing some examples, the article continues:
It is, however, very certain, that at a city festival some years ago, having indulged very freely, he fell asleep, when some wag, choosing to consider him dead, wrote his epitaph, which was found next morning pinned to the baronet's dress coat:--
"Here lies the great Curtis,
Of London, Lord May'r:
He's left this here world,
And gone to that there."
- threefold (adj.)
- late Old English þrifeald; see three + -fold.
- threesome (n.)
- late 14c., from three + -some (2).
- threnody (n.)
- "song of lamentation," 1630s, from Greek threnodia "lamentation," from threnos "dirge, lament" + oide "ode" (see ode). Greek threnos probably is from PIE imitative root *dher- (3) "to drone, murmur, hum;" source also of Old English dran "drone," Gothic drunjus "sound," Greek tenthrene "a kind of wasp."
- thresh (v.)
- Old English þrescan, þerscan, "to beat, sift grain by trampling or beating," from Proto-Germanic *threskan "to thresh," originally "to tread, to stamp noisily" (source also of Middle Dutch derschen, Dutch dorschen, Old High German dreskan, German dreschen, Old Norse þreskja, Swedish tröska, Gothic þriskan), from PIE root *tere- (1) "to rub, turn" (see throw (v.)).
The basic notion is of men or oxen treading out wheat; later, with the advent of the flail, the word acquired its modern extended sense of "to knock, beat, strike." The original Germanic sense is suggested by the use of the word in Romanic languages that borrowed it, such as Italian trescare "to prance," Old French treschier "to dance," Spanish triscar "to stamp the feet."
- thresher (n.)
- late 14c., agent noun from thresh. The thresher shark (c. 1600) so called for its long upper tail, which resembles a threshing tool.
- threshold (n.)
- Old English þrescold, þærscwold, þerxold, etc., "door-sill, point of entering," of uncertain origin and probably much altered by folk-etymology. The first element probably is related to Old English þrescan (see thresh), either in its current sense of "thresh" or with its original sense of "tread, trample." Second element has been much transformed in all the Germanic languages, suggesting its literal sense was lost even in ancient times. In English it probably has been altered to conform to hold. Liberman (Oxford University Press blog, Feb. 11, 2015) revives an old theory that the second element is the Proto-Germanic instrumental suffix *-thlo and the original sense of threshold was a threshing area adjacent to the living area of a house. Cognates include Old Norse þreskjoldr, Swedish tröskel, Old High German driscufli, German dialectal drischaufel. Figurative use was in Old English.
- past tense of throw (q.v.).

- c. 1300, "fact or condition of thriving," also "prosperity, savings," from Middle English thriven "to thrive" (see thrive), influenced by (or from) Old Norse þrift, variant of þrif "prosperity," from þrifask "to thrive." Sense of "habit of saving, economy" first recorded 1550s (thrifty in this sense is recorded from 1520s; also see spendthrift). Thrift shop attested by 1919.

Related: Thrived (or throve); thriving.
- thro (prep.)
- shorter spelling of through.
- throat (n.)
- Old English þrote (implied in þrotbolla "the Adam's apple, larynx," literally "throat boll"), related to þrutian "to swell," from Proto-Germanic *thrut- (source also of Old High German drozza, German Drossel, Old Saxon strota, Middle Dutch strote, Dutch strot "throat"), of uncertain origin. Italian strozza "throat," strozzare "to strangle" are Germanic loan-words. College slang for "competitive student" is 1970s, from cutthroat.

- c. 1200, throwe "pain, pang of childbirth, agony of death," of uncertain origin, possibly from Old English þrawan "twist, turn, writhe" (see throw (v.)), or altered from Old English þrea (genitive þrawe) "affliction, pang, evil; threat, persecution" (related to þrowian "to suffer"), from Proto-Germanic *thrawo (source also of Middle High German dro "threat," German drohen "to threaten").
