c. 1200, from Old Norse geta (past tense gatum, past participle getenn) "to obtain, reach; to be able to; to beget; to learn; to be pleased with," a word of very broad meaning, often used almost as an auxilliary verb, also frequently in phrases (such as geta rett "to guess right"). This is from Proto-Germanic *getan (source also of Old Swedish gissa "to guess," literally "to try to get"), from PIE root *ghend- "to seize, take."
Old English, as well as Dutch and Frisian, had the verb almost exclusively in compounds (such as begietan, "to beget;" forgietan "to forget"). Vestiges of an Old English cognate *gietan remain obliquely in modern past participle gotten and original past tense gat, also Biblical begat.
In compound phrases with have and had it is grammatically redundant, but often usefully indicates possession, obligation, or necessity, or gives emphasis. The word and phrases built on it take up 29 columns in the OED 2nd edition; Century Dictionary lists seven distinct senses for to get up.
"I GOT on Horseback within ten Minutes after I received your Letter. When I GOT to Canterbury I GOT a Chaise for Town. But I GOT wet through before I GOT to Canterbury, and I HAVE GOT such a Cold as I shall not be able to GET rid of in a Hurry. I GOT to the Treasury about Noon, but first of all I GOT shaved and drest. I soon GOT into the Secret of GETTING a Memorial before the Board, but I could not GET an Answer then, however I GOT Intelligence from the Messenger that I should most likely GET one the next Morning. As soon as I GOT back to my Inn, I GOT my Supper, and GOT to Bed, it was not long before I GOT to Sleep. When I GOT up in the Morning, I GOT my Breakfast, and then GOT myself drest, that I might GET out in Time to GET an Answer to my Memorial. As soon as I GOT it, I GOT into the Chaise, and GOT to Canterbury by three: and about Tea Time, I GOT Home. I HAVE GOT No thing particular for you, and so Adieu." [Philip Withers, "Aristarchus, or the Principles of Composition," London, 1789, illustrating the widespread use of the verb in Modern English]
As a command to "go, be off" by 1864, American English. Meaning "to seize mentally, grasp" is from 1892. Get wind of "become acquainted with" is from 1840, from earlier to get wind "to get out, become known" (1722). To get drunk is from 1660s; to get religion is from 1772; to get better "recover health" is from 1776. To get ready "prepare oneself" is from 1890; to get going "begin, start doing something" is by 1869 in American English; get busy "go into action, begin operation" is from 1904. Get lost as a command to go away is by 1947. To get ahead "make progress" is from 1807. To get to (someone) "vex, fret, obsess" is by 1961, American English (get alone as "to puzzle, trouble, annoy" is by 1867, American English). To get out of hand originally (1765) meant "to advance beyond the need for guidance;" sense of "to break free, run wild" is from 1892, from horsemanship. To get on (someone's) nerves is attested by 1970.
Old English fyr "fire, a fire," from Proto-Germanic *fūr- (source also of Old Saxon fiur, Old Frisian fiur, Old Norse fürr, Middle Dutch and Dutch vuur, Old High German fiur, German Feuer "fire"), from PIE *perjos, from root *paewr- "fire." Current spelling is attested as early as 1200, but did not fully displace Middle English fier (preserved in fiery) until c. 1600.
PIE apparently had two roots for fire: *paewr- and *egni- (source of Latin ignis). The former was "inanimate," referring to fire as a substance, and the latter was "animate," referring to it as a living force (compare water (n.1)).

English fire was applied to "ardent, burning" passions or feelings from mid-14c. Meaning "discharge of firearms, action of guns, etc." is from 1580s. To be on fire is from c. 1500 (in fire attested from c. 1400, as is on a flame "on fire"). To play with fire in the figurative sense "risk disaster, meddle carelessly or ignorantly with a dangerous matter" is by 1861, from the common warning to children. Phrase where's the fire?, said to one in an obvious hurry, is by 1917, American English.
Fire-bell is from 1620s; fire-alarm as a self-acting, mechanical device is from 1808 as a theoretical creation; practical versions began to appear in the early 1830s. Fire-escape (n.) is from 1788 (the original so-called was a sort of rope-ladder disguised as a small settee); fire-extinguisher is from 1826. A fire-bucket (1580s) carries water to a fire. Fire-house is from 1899; fire-hall from 1867, fire-station from 1828. Fire company "men for managing a fire-engine" is from 1744, American English. Fire brigade "firefighters organized in a body in a particular place" is from 1838. Fire department, usually a branch of local government, is from 1805. Fire-chief is from 1877; fire-ranger from 1909.
Symbolic fire and the sword is by c. 1600 (translating Latin flamma ferroque absumi); earlier yron and fyre (1560s), with suerd & flawme (mid-15c.), mid fure & mid here ("with fire and armed force"), c. 1200. Fire-breathing is from 1590s. To set the river on fire, "accomplish something surprising or remarkable" (usually with a negative and said of one considered foolish or incompetent) is by 1830, often with the name of a river, varying according to locality, but the original is set the Thames on fire (1796). The hypothetical feat was mentioned as the type of something impossibly difficult by 1720; it circulated as a theoretical possibility under some current models of chemistry c. 1792-95, which may have contributed to the rise of the expression.
[A]mong other fanciful modes of demonstrating the practicability of conducting the gas wherever it might be required, he anchored a small boat in the stream about 50 yards from the shore, to which he conveyed a pipe, having the end turned up so as to rise above the water, and forcing the gas through the pipe, lighted it just above the surface, observing to his friends "that he had now set the river on fire." ["On the Origins and Progress of Gas-lighting," in "Repertory of Patent Inventions," vol. III, London, 1827]
"to have sexual intercourse with" (transitive), until recently a difficult word to trace in usage, in part because it was omitted as taboo by the editors of the original OED when the "F" entries were compiled (1893-97). Johnson also had excluded the word, and fuck wasn't in a single English language dictionary from 1795 to 1965. "The Penguin Dictionary" broke the taboo in the latter year. Houghton Mifflin followed, in 1969, with "The American Heritage Dictionary," but it also published a "Clean Green" edition without the word, to assure itself access to the public high school market.
Written form attested from at least early 16c.; OED 2nd edition cites 1503, in the form fukkit, and the earliest attested appearance of current spelling is 1535 ("Bischops ... may fuck thair fill and be vnmaryit" [Sir David Lyndesay, "Ane Satyre of the Thrie Estaits"]). Presumably it is a more ancient word, but one not written in the kind of texts that have survived from Old English and Middle English [September 2015: the verb appears to have been found recently in an English court manuscript from 1310]. Buck cites proper name John le Fucker from 1278, but that surname could have other explanations. The word apparently is hinted at in a scurrilous 15c. poem, titled "Flen flyys" ["Fleas, Flies (and Friars)"], written in bastard Latin and Middle English. The relevant line reads:
Non sunt in celi
quia fuccant uuiuys of heli
"They [the monks] are not in heaven because they fuck the wives of [the town of] Ely." Fuccant is pseudo-Latin, and in the original it is written in cipher. The earliest examples of the word otherwise are from Scottish, which suggests a Scandinavian origin, perhaps from a word akin to Norwegian dialectal fukka "copulate," or Swedish dialectal focka "copulate, strike, push," and fock "penis."
Another theory traces the Modern English verb to Middle English fyke, fike "move restlessly, fidget" (see fike) which also meant "dally, flirt," and probably is from a general North Sea Germanic word (compare Middle Dutch fokken, German ficken "fuck," earlier "make quick movements to and fro, flick," still earlier "itch, scratch;" the vulgar sense attested from 16c.). This would parallel in sense the vulgar Middle English term for "have sexual intercourse," swive, from Old English swifan "to move lightly over, sweep" (see swivel). But OED remarks that these "cannot be shown to be related" to the English word. Liberman has this to say:
Germanic words of similar form (f + vowel + consonant) and meaning 'copulate' are numerous. One of them is G. ficken. They often have additional senses, especially 'cheat,' but their basic meaning is 'move back and forth.' ... Most probably, fuck is a borrowing from Low German and has no cognates outside Germanic.
Chronology and phonology rule out Shipley's attempt to derive it from Middle English firk "to press hard, beat." The unkillable urban legend that this word is an acronym of some sort (a fiction traceable on the internet to 1995 but probably predating that), and the "pluck yew" fable, are results of ingenious trifling (also see here). The Old English verb for "have sexual intercourse with" was hæman, from ham "dwelling, home," with a sense of "take home, co-habit." French foutre and Italian fottere seem to resemble the English word but are unrelated, descending rather from Latin futuere, which perhaps is from PIE root *bhau- "to strike," extended via a figurative use "from the sexual application of violent action" [Shipley; compare the sexual slang use of bang, etc.].
Fuck was outlawed in print in England (by the Obscene Publications Act, 1857) and the U.S. (by the Comstock Act, 1873). The word continued in common speech, however. During World War I:
It became so common that an effective way for the soldier to express this emotion was to omit this word. Thus if a sergeant said, 'Get your ----ing rifles!' it was understood as a matter of routine. But if he said 'Get your rifles!' there was an immediate implication of urgency and danger. [John Brophy, "Songs and Slang of the British Soldier: 1914-1918," pub. 1930]
The legal barriers against use in print broke down in mid-20c. with the "Ulysses" decision (U.S., 1933) and "Lady Chatterley's Lover" (U.S., 1959; U.K., 1960). The major breakthrough in publication was James Jones' "From Here to Eternity" (1950), with 50 fucks (down from 258 in the original manuscript).
The abbreviation F (or eff) probably began as euphemistic, but by 1943 it was regarded as a cuss word in its own right. In 1948, the publishers of "The Naked and the Dead" persuaded Norman Mailer to use the euphemism fug. When Mailer later was introduced to Dorothy Parker, she greeted him with, "So you're the man who can't spell 'fuck' " [The quip sometimes is attributed to Tallulah Bankhead]. As a written euphemism, muck is attested by 1929 (Hemingway used it in "For Whom the Bell Tolls," 1940). Related: Fucked; fucking.
Fuck-all "nothing" first recorded 1960. Verbal phrase fuck up "to ruin, spoil, destroy" is attested from c. 1916. A widespread group of Slavic words (such as Polish pierdolić) can mean both "fornicate" and "make a mistake." Fuck off is attested from 1929; as a command to depart, by 1944. Egyptian legal agreements from the 23rd Dynasty (749-21 B.C.E.) frequently include the phrase, "If you do not obey this decree, may a donkey copulate with you!" [Reinhold Aman, "Maledicta," Summer 1977].
