tea party (n.)

c. 1300, partie, "a part, division, section, portion," a sense now obsolete; also "physical piece, fragment; section of a book or treatise," from Old French partie "side, part; portion, share; separation, division" (12c.), literally "that which is divided," noun use of fem. past participle of partir "to divide, separate" (10c.), from Latin partire/partiri "to share, part, distribute, divide," from pars "a part, piece, a share" (from PIE root *pere- (2) "to grant, allot").

In early use the word often appears where we would have its relative part (n.). Also from c. 1300 in the legal sense "person or group of persons involved in a lawsuit, agreement, etc.," and in the political sense of "a number of persons united in supporting a person, policy, or cause." From early 14c. as any "group of people," also "a social class." Meaning "a person, a paritcular person" is from mid-15c.

The military sense of "a detached part of a larger body or company" is by 1640s. The sense of "a gathering for social pleasure" is found by 1716, from general sense of persons gathered (originally for some specific, temporary purpose, such as dinner party, hunting party).

Phrase the party is over "enjoyment or pleasant times have come to an end" is from 1937; party line is recorded by 1834 in the sense of "policy adopted by a political party," and by 1893 in the sense of "telephone line shared by two or more subscribers." Party pooper "one who casts gloom over a convivial event" is from 1951, American English.

1650s, tay, "prepared leaves of the tea plant," also "an infusion of prepared tea leaves used as a beverage," also in early spellings thea, tey, tee and at first pronounced so as to rhyme with obey (Pope); pay (Gay). The modern pronunciation predominates from mid-18c.

The word is earliest in English as chaa (1590s), also cha, tcha, chia, cia (compare cha, chai). The two forms reflect two paths of transmission: chaa, etc. are from Portuguese cha, via Macao, from Mandarin (Chinese) ch'a. The later form, which became Modern English tea, is via Dutch thee, from Malay teh and directly from Chinese (Amoy dialect) t'e, which corresponds to Mandarin ch'a.

The modern English form (along with French thé, Spanish te, German Tee, etc.) reflects the role of the Dutch as chief importers of the leaves in that part of Europe (through the Dutch East India Company, from 1610). Meanwhile, Russian chai, Persian cha, Greek tsai, Arabic shay, and Turkish çay all came by overland trade routes from the Mandarin form.

Tea was known in Paris by 1635; the practice of drinking it was introduced in England by 1644. The word was extended by 1660s to the tea plant itself, also to similar infusions of the parts of other plants. The slang meaning "marijuana" (which sometimes was brewed in hot water) is attested by 1935, felt as obsolete by late 1960s.

The meaning "late afternoon meal at which tea is served" is by 1738. Tea-bottle as English slang for "old maid" is attested by 1909. To not do something for all the tea in China "not for anything" is colloquial, attested by 1947 in Australian English, said to date from 1890s.

U.S. city, 1630, named for the town in Lincolnshire, which sent many Puritan settlers to early New England. The name is said to be literally "Botolph's Stone," probably from the name of some Anglo-Saxon landowner (Old English Botwulf). The Boston Massacre was March 5, 1770; three civilians killed, two mortally wounded. The Boston Tea Party (1824) took place on Dec. 16, 1773 (see tea party). Related: Bostonian.
