"The development of such a verb from a noun of limited use like tangle 1 is somewhat remarkable, and needs confirmation" [Century Dictionary]. In reference to material things, from c. 1500. Meaning "to fight with" is American English, first recorded 1928. Related: Tangled; tangling. Tanglefoot (1859) was Western American English slang for "strong whiskey."
tango (n.) Look up tango at Dictionary.com
syncopated ballroom dance, 1913 (the year it became a rage in Britain and America), from Argentine Spanish tango, originally the name of an African-South American drum dance, probably from a Niger-Congo language (compare Ibibio tamgu "to dance"). Phrase it takes two to tango was a song title from 1952. As a verb from 1913. Related: Tangoed.
It is hardly a year ago since the Tango reached this country from South America by way of Paris. It was at first no more than a music-hall freak. But some of those mysterious people who inspire new social fashions were attracted by its sinuous movements and the strange backward kick, and this year it made its way into private houses as well as public ball rooms. [The Living Age, Dec. 13, 1913]

"I need not describe the various horrors of American and South American negroid origin. I would only ask hostesses to let one know what houses to avoid by indicating in some way on their invitation cards whether the 'turkey-trot,' the 'Boston' (the beginner of the evil), and the 'tango' will be permitted." [quoted in "Current Opinion," October 1913, as from a letter to the London Times]
tangram (n.) Look up tangram at Dictionary.com
Chinese geometric puzzle, 1864, said to be an arbitrary formation based on anagram, etc. First element perhaps Chinese t'an "to extend," or t'ang, commonly used in Cantonese for "Chinese."

Another theory involves the Tanka, an outcast aboriginal people of southern China, and Western sailors who discovered the puzzle from their Tanka girlfriends. Perhaps from an obscure sense of tram. The Chinese name is Ch'i ch'iao t'u "seven ingenious plan."

tank (n.) Look up tank at Dictionary.com
1610s, "pool or lake for irrigation or drinking water," a word originally brought by the Portuguese from India, from a Hindi source, such as Gujarati tankh "cistern, underground reservoir for water," Marathi tanken, or tanka "reservoir of water, tank." Perhaps ultimately from Sanskrit tadaga-m "pond, lake pool," and reinforced in later sense of "large artificial container for liquid" (1680s) by Portuguese tanque "reservoir," from estancar "hold back a current of water," from Vulgar Latin *stanticare (see stanch). But other sources say the Portuguese word is the source of the Indian ones. Meaning "fuel container" is recorded from 1902. Slang meaning "detention cell" is from 1912. Railroad tank-car is from 1874.

In military use, "armored, gun-mounted vehicle moving on continuous articulated tracks," the word originated late 1915. In "Tanks in the Great War" [1920], Brevet Col. J.F.C. Fuller quotes a memorandum of the Committee of Imperial Defence dated Dec. 24, 1915, recommending the proposed "caterpillar machine-gun destroyer" machines be entrusted to an organization "which, for secrecy, shall be called the 'Tank Supply Committee,' ..." In a footnote, Fuller writes, "This is the first appearance of the word 'tank' in the history of the machine." He writes that "cistern" and "reservoir" also were put forth as possible cover names, "all of which were applicable to the steel-like structure of the machines in the early stages of manufacture. Because it was less clumsy and monosyllabic, the name 'tank' was decided on." They were first used in action at Pozieres ridge, on the Western Front, Sept. 15, 1916, and the name was quickly picked up by the soldiers. Tank-trap attested from 1920.

1900, "to put into a tank," from tank (n.). Meaning "to lose or fail" attested from 1976 in a general sense, apparently originally in tennis jargon, specifically in an interview with Billie Jean King in "Life" magazine, Sept. 22, 1967:
"When our men don't feel like trying," she says, "They 'tank' [give up]. I never tanked a match in my life and I never saw a girl do it. The men do it all the time in minor tournaments when they don't feel like hustling. You have to be horribly competitive to win in big-time tennis."
