The distribution of the different forms of the word in Europe reflects the spread of use of the beverage. The modern English form, along with French thé, Spanish te, German Tee, etc., derive via Dutch thee from the Amoy form, reflecting the role of the Dutch as the chief importers of the leaves (through the Dutch East India Company, from 1610). Meanwhile, Russian chai, Persian cha, Greek tsai, Arabic shay, and Turkish çay all came overland from the Mandarin form.
First known in Paris 1635, the practice of drinking tea was first introduced to England 1644. Meaning "afternoon meal at which tea is served" is from 1738. Slang meaning "marijuana" (which sometimes was brewed in hot water) is attested from 1935, felt as obsolete by late 1960s. Tea ball is from 1895.
"pledged to total abstinence from intoxicating drink," 1834, a word possibly formed from total (adj.) with a reduplication of the initial T- for emphasis (T-totally "totally," though not in an abstinence sense, is recorded in Kentucky dialect from 1832 and is possibly older in Irish-English).
The use in temperance jargon was first noted September 1833 in a speech advocating total abstinence (from beer as well as wine and liquor) by Richard "Dicky" Turner, a working-man from Preston, England. Also said to have been introduced in 1827 in a New York temperance society which recorded a T after the signature of those who had pledged total abstinence, but contemporary evidence for this is wanting, and while Century Dictionary allows that "the word may have originated independently in the two countries," OED favors the British origin and notes that Webster (1847) calls teetotaler "a cant word formed in England."
1843, "to seesaw," alteration of Middle English titter "move unsteadily," probably from a Scandinavian source akin to Old Norse titra "to shake, shiver, totter, tremble," from Proto-Germanic *ti-tra- (source also of German zittern "to tremble"). Meaning "move unsteadily, be on the edge of imbalance" is from 1844.
Noun teeter-totter "see-saw" is attested from 1871 (earlier simply teeter, 1855, and titter-totter in same sense is from 1520s). Totter (n.) "board swing" is recorded from late 14c.; see totter (v.), and compare see-saw.
