Meaning "to free an occupied territory from the enemy" (often used ironically) is from 1942; hence the World War II slang sense "to loot." Related: Liberated; liberating.

1793, "a destroyer of liberty," from liberty + -cide "killer." Earlier in French. From 1819 as "the destruction of liberty."
libertine (n.)
late 14c., "a freedman, an emancipated slave," from Latin libertinus "condition of a freedman; member of a class of freedmen," from libertus "one's freedmen, emancipated person," from liber "free" (see liberal (adj.)).

Sense of "freethinker" is first recorded 1560s, from French libertin (1540s) originally the name given to certain pantheistic Protestant sects in France and the Low Countries. This sense partakes more of liberty and liberal than of the classical meaning (in Old French, libertin meant "Saracen slave converted to Christianity"). Meaning "dissolute or licentious person, man given to indulgence of lust" is first recorded 1590s; the darkening of meaning being perhaps due to misunderstanding of Latin libertinus in Acts vi:9. For "condition of being a libertine" 17c English tried libertinage; libertinism (from French libertinisme).

At first of persons; of communities, "state of being free from arbitrary, despotic, or autocratic rule or control" is from late 15c.
The French notion of liberty is political equality; the English notion is personal independence. [William R. Greg, "France in January 1852" in "Miscellaneous Essays"]
Nautical sense of "leave of absence" is from 1758. Meaning "unrestrained action, conduct, or expression" (1550s) led to take liberties "go beyond the bounds of propriety" (1620s). Sense of "privileges by grant" (14c.) led to sense of "a person's private land" (mid-15c.), within which certain special privileges may be exercised, which yielded in 18c. in both England and America a sense of "a district within a county but having its own justice of the peace," and also "a district adjacent to a city and in some degree under its municipal jurisdiction" (as in Northern Liberties of Philadelphia). Also compare Old French libertés "local rights, laws, taxes."

Liberty-cap is from 1803; the American Revolutionary liberty-pole, "tall flagstaff set up in honor of liberty and often surmounted by a liberty-cap" is from 1775. Liberty-cabbage was a World War I U.S. jingoistic euphemism for sauerkraut.
libidinal (adj.)
in psychology jargon, 1922, in Joan Riviere's translation of Freud, from comb. form of libido (Latin genitive libidinis) + -al (1).
libidinous (adj.)
"lustful," mid-15c., from Old French libidineus "sinful, lusty" (13c., Modern French libidineux) or directly from Latin libidinosus "full of desire, lustful," from libido "pleasure, desire, sensual passion, lust" (see libido). Related: Libidinously; libidinousness; libidinosity. These are older in English than libido, libidinal, which are from modern psychology.
libido (n.)
"psychic drive or energy, usually associated with sexual instinct," 1892, carried over untranslated in English edition of Krafft-Ebing's "Psychopathia Sexualis"; and used in 1909 in A.A. Brill's translation of Freud's "Selected Papers on Hysteria" (Freud's use of the term led to its popularity); from Latin libido, lubido "desire, eagerness, longing; inordinate desire, sensual passion, lust," from libere "to be pleasing, to please," from PIE root *leubh- "to care, desire, love" (source also of love).
Libra (n.)
zodiac constellation represented by a pair of scales, late Old English, from Latin libra "a balance, pair of scales," also "pound (unit of weight)," from Proto-Italic *leithra- "pound." De Vaan compares Greek litra "name of a Sicilian coin," which "was probably borrowed from an Italic language at the stage containing [-thr-]."

Not a separate constellation in ancient Greece, where it was khelae, "the claws" of adjacent Skorpios. Nativized in Old Norse as skala-merki. Meaning "person born under the sign of Libra" is from 1894. Related: Libral; Libran.
librarian (n.)
"custodian of a library," 1713; see library + -an. Earlier form was library-keeper (1640s), and librarian had been used in the sense "scribe, one who copies books" (1660s).
library (n.)
place for books, late 14c., from Anglo-French librarie, Old French librairie, librarie "collection of books; bookseller's shop" (14c.), from Latin librarium "book-case, chest for books," and libraria "a bookseller's shop," in Medieval Latin "a library," noun uses of the neuter and fem., respectively, of librarius "concerning books," from Latin librarium "chest for books," from liber (genitive libri) "book, paper, parchment."

Latin liber (from Proto-Italic *lufro-) was originally "the inner bark of trees," and perhaps is from PIE *lubh-ro- "leaf, rind," a derivative of the PIE root *leub(h)- "to strip, to peel" (see leaf (n.)). Comparing Albanian labë "rind, cork;" Lithuanian luobas "bast," Latvian luobas "peel," Russian lub "bast," de Vaan writes that, "for want of a better alternative, we may surmise that liber is cognate with *lubh- and goes back to a PIE word or a European word 'leaf, rind.'"

The equivalent word in most Romance languages survives only in the sense "bookseller's shop" (French libraire, Italian libraria). Old English had bochord, literally "book hoard." As an adjective, Blount (1656) has librarious.
libre (adj.)
"free," a French word used in various combinations in English since 16c., from French libre, from Latin liber "free" (see liberal (adj.)).
libretto (n.)
plural libretti, "book containing the words of an extended musical composition," also the words themselves, 1742, from Italian libretto, diminutive of libro "book," from Latin liber (genitive libri) "book" (see library). Related: Librettist (1849).

Libya
ancient name for the northern part of Africa west of Egypt, attested in heiroglyphics from 2000 B.C.E., of unknown origin. In Greek use, sometimes meaning all of Africa. The modern nation acquired the name in 1934, when Italy, which then held it as a colony, revived the name as that of the colony, which became formally independent in 1951. Related: Libyan (adj. and n., both c. 1600), earlier as an adjective Lybic (1540s); as a noun, for the inhabitants and the country, Middle English had Libie. Comb. form Libyo-.
licence (n.)
late 14c., "formal authorization, official permission, permit, privilege," from Old French licence "freedom, liberty, power, possibility; permission," (12c.), from Latin licentia "freedom, liberty; unrestrained liberty, wantonness, presumption," from licentem (nominative licens), present participle of licere "to be allowed, be lawful," from PIE root *leik- "to offer, bargain, make a bid" (possibly source also of Lettish likstu "I come to terms").

Meaning "formal (usually written) permission from authority to do something" (marry, hunt, drive, etc.) is first attested early 15c. Meaning "excessive liberty, disregard of propriety" in English is from mid-15c. In Middle English spelled licence, licens, lisence, lissens, licance. There have been attempts to confine license to verbal use and licence to noun use (compare advise/advice, devise/device, and see note in OED).

Poetic license "intentional deviation from recognized form or rule" is from 1733, earlier as lycence poetycall (1530). The licence-plate is from 1870 (of dogs and wagons before automobiles); licence-number is by 1903.

c. 1400, "grant formal authorization to do what would be illegal to do without it," from licence (n.), which see for modern differentiation of spelling. Related: Licensed; Licensing.

lich (n.)
also litch, lych, "body, corpse," a southern England dialectal survival of Old English lic "body, dead body, corpse," from Proto-Germanic *likow (source also of Old Frisian lik, Dutch lijk, Old High German lih, German Leiche "corpse, dead body," Old Norse lik, Danish lig, Swedish lik, Gothic leik), probably originally "form, shape," and identical with like (adj.).

Also in Old English in an expanded form lichama (Middle English licham), with hama "shape, garment, covering." This is etymologically pleonastic, but the image perhaps is of the body as the garment of the soul. The compound has a cognate in Old High German lihhinamo. A litch-gate (also lych-gate) was a roofed gate to a churchyard under which a bier is placed to await the coming of the clergyman; lich-owl "screech-owl" was so called because it was supposed to forebode death. Old English also had licburg "cemetery," lichhaemleas "incorporeal."
lichen (n.)
1715, from Latin lichen, from Greek leichen "tree-moss, lichen," originally "what eats around itself," probably from leichein "to lick" (from PIE root *leigh- "to lick").

lick (n.)
"an act of licking," c. 1600, from lick (v.1). The earlier noun was licking (late 14c.; Old English had liccungMeaning "small portion" is 1814, originally Scottish; hence U.S. colloquial sense.

The jazz music sense of "short figure or solo" is by 1922, perhaps from an earlier colloquial sense "a spurt or brisk run in racing" (1809). Meaning "a smart blow" (1670s) is from lick (v.2).
lick (v.2)
"to beat, surpass, overcome" 1535, perhaps from figurative use of lick (v.1) in the Coverdale bible that year in sense of "defeat, annihilate" (an enemy's forces) in Numbers xxii.4:

lickerish (adj.)
"fond of delicious fare," c. 1500, a corruption (as if from licker or liquor + -ish) of Middle English likerous "pleasing to the palate" (late 13c.), from Anglo-French *likerous, Old French licherous (see lecherous). Unlike the French word, it generally kept close to its literal sense. Related: Lickerishly; lickerishness.
lickety-split (adj.)
1852, American English; earlier lickety-cut, lickety-click, and simply licketie (1817), probably a fanciful extension of lick (n.1) in its dialectal sense of "very fast sprint in a race" (1809) on the notion of a flick of the tongue as a fast thing (compare blink, snap).

lid (n.)
"movable or removable cover for a pot, etc.," mid-13c., from Old English hlid "covering, opening, gate," from Proto-Germanic *hlid- "cover," literally "that which bends over" (source also of Old Norse hlið "gate, gap," Swedish lid "gate," Old French hlid, Middle Dutch lit, Dutch lid, Old High German hlit "lid, cover"), from PIE root *klei- "to lean."

Meaning "eyelid" is from early 13c. Slang sense of "hat, cap" is attested from 1896.

To give the lie to "accuse directly of lying" is attested from 1590s. Lie-detector first recorded 1909.
