lie (n.1): "an untruth, false statement made with intent to deceive," Old English lyge, lige "lie, falsehood," from Proto-Germanic *lugiz (source also of Old Norse lygi, Danish løgn, Old Frisian leyne (fem.), Dutch leugen (fem.), Old High German lugi, German Lüge, Gothic liugn "a lie"), from the root of lie (v.1). To give the lie to "accuse directly of lying" is attested from 1590s. Lie-detector first recorded 1909.
In mod. use, the word is normally a violent expression of moral reprobation, which in polite conversation tends to be avoided, the synonyms falsehood and untruth being often substituted as relatively euphemistic. [OED]
lie (n.2): "manner of lying, relative position," 1690s, from lie (v.2). Sense in golf is from 1857.
lie (v.2): "rest horizontally, be in a recumbent position," early 12c., from Old English licgan (class V strong verb; past tense læg, past participle legen) "be situated, have a specific position; remain; be at rest, lie down," from Proto-Germanic *legjan (source also of Old Norse liggja, Old Saxon liggian, Old Frisian lidzia, Middle Dutch ligghen, Dutch liggen, Old High German ligen, German liegen, Gothic ligan "to lie"), from PIE *legh- "to lie, lay" (source also of Hittite laggari "falls, lies;" Greek lekhesthai "to lie down," legos "bed," lokhos "lying in wait, ambush," alokhos "bedfellow, wife;" Latin lectus "bed;" Old Church Slavonic lego "to lie down;" Lithuanian at-lagai "fallow land;" Old Irish laigim "I lie down," Irish luighe "couch, grave").

To lie in "be brought to childbed" is from mid-15c. To lie to at sea is to come to a standstill. To take (something) lying down "receive passively, receive with abject submission" is from 1854.
lie (v.1): "speak falsely, tell an untruth for the purpose of misleading," late 12c., from Old English legan, ligan, earlier leogan "deceive, belie, betray" (class II strong verb; past tense leag, past participle logen), from Proto-Germanic *leugan (source also of Old Norse ljuga, Danish lyve, Old Frisian liaga, Old Saxon and Old High German liogan, German lügen, Gothic liugan), from PIE root *leugh- "to tell a lie" (source also of Old Church Slavonic lugati, Russian luigatĭ; not found in Latin, Greek, or Sanskrit).

belie (v.): Old English beleogan "to deceive by lies," from be- + lie (v.1) "to lie, tell lies." Current sense of "to contradict as a lie" is first recorded 1640s. The other verb lie once also had a formation like this, from Old English belicgan, which meant "to encompass, beleaguer," and in Middle English was a euphemism for "to have sex with" (i.e. "to lie with carnally").
lay (v.): "to cause to lie or rest," Old English lecgan "to place on the ground (or other surface); place in an orderly fashion," also "put down" (often by striking), from Proto-Germanic *lagjan (source also of Old Saxon leggian, Old Norse leggja, Old Frisian ledza, Middle Dutch legghan, Dutch leggen, Old High German lecken, German legen, Gothic lagjan "to lay, put, place"). This is a causative form of the ancient Germanic verb that became modern English lie (v.2).

Meaning "have sex with" first recorded 1934, in U.S. slang, probably from sense of "bring forth and deposit" (which was in Old English, as in lay an egg, lay a bet, etc.), perhaps reinforced by to lie with, a phrase frequently met in the Bible. To lay for (someone) "await a chance at revenge" is from late 15c.; lay low "stay inconspicuous" is from 1839; to lay (someone) low preserves the secondary Old English sense.

"The form in -ar is probably in imitation of the refashioned forms such as scholar for scoler and pillar for piler" [Barnhart]. A different formation yielded Dutch leugenaar, Old High German luginari, German Lügner, Danish lögner.
low (adj.): "not high," late 13c., from lah (late 12c.), "not rising much, being near the base or ground" (of objects or persons); "lying on the ground or in a deep place" (late 13c.), from Old Norse lagr "low," or a similar Scandinavian source (compare Swedish låg, Danish lav), from Proto-Germanic *lega- "lying flat, low" (source also of Old Frisian lech, Middle Dutch lage, Dutch laag "low," dialectal German läge "flat"), from PIE *legh- "to lie" (see lie (v.2)).

Meaning "humble in rank" is from c. 1200; "undignified" is from 1550s; sense of "dejected, dispirited" is attested from 1737; meaning "coarse, vulgar" is from 1759.

Similar formation in Old High German untarliggan; German unterliegen.
beleaguer (v.): 1580s, from Dutch or Low German belegeren "to besiege," from be- "around" (see be-) + legeren "to camp," from leger "bed, camp, army, lair," from Proto-Germanic *leg-raz-, from PIE *legh-to- "lie" (see lie (v.2)). A word from the Flemish Wars (cognates: Swedish belägra, Dutch belegeren "besiege," German Belagerung "siege"). Spelling influenced by league. Related: Beleaguered; beleaguering.

Meaning "animal's den" is from early 15c. Essentially the same word as layer (n.), but more ancient and differentiated in sense.
litter (n.): c. 1300, "a bed," also "bed-like vehicle carried on men's shoulders" (early 14c.), from Anglo-French litere "portable bed," Old French litiere "litter, stretcher, bier; straw, bedding" (12c.), from Medieval Latin lectaria "litter," from Latin lectus "bed, lounge, sofa, dining-couch," from PIE *legh-to-, suffixed form of root *legh- "to lie" (see lie (v.2)).

Altered in French by influence of lit "bed." The meaning was extended early 15c. to "straw used for bedding" (this sense is early 14c. in Anglo-French) and by late 15c. to "offspring of an animal at one birth" (that is, in one bed). Litter by 19c. had come to mean both the straw bedding and the animal waste in it after use. The sense of "scattered oddments, disorderly debris" is first attested 1730 and probably is from litter (v.) "provide with bedding" (late 14c.) and sense extended from the image of strewing straw.
stately (adj.): "noble, splendid," late 14c., from -ly (1) + state (n.1) in a sense of "costly and imposing display" (such as benefits a person of rank and wealth), attested from early 14c.

warlock (n.): Old English wærloga "traitor, liar, enemy, devil," from wær "faith, fidelity; a compact, agreement, covenant," from Proto-Germanic *wera- (source also of Old High German wara "truth," Old Norse varar "solemn promise, vow"), from PIE *were-o- "true, trustworthy" (see very, also Varangian). Second element is an agent noun related to leogan "to lie" (see lie (v.1); and compare Old English wordloga "deceiver, liar").

Original primary sense seems to have been "oath-breaker;" given special application to the devil (c. 1000), but also used of giants and cannibals. Meaning "one in league with the devil" is recorded from c. 1300. Ending in -ck (1680s) and meaning "male equivalent of a witch" (1560s) are from Scottish. Related: Warlockery.

Sense of "something that is true" is first recorded mid-14c. Meaning "accuracy, correctness" is from 1560s. English and most other IE languages do not have a primary verb for for "speak the truth," as a contrast to lie (v.). Truth squad in U.S. political sense first attested in the 1952 U.S. presidential election campaign.
At midweek the Republican campaign was bolstered by an innovation--the "truth squad" ..., a team of senators who trailed whistle-stopping Harry Truman to field what they denounced as his wild pitches. ["Life," Oct. 13, 1952]

An officious lie (1570s) is one told to do good to another person (from Latin mendocium officiosum or French mensonge officieux). Related: Officiousness.
rely (v.): early 14c., "to gather, assemble" (transitive and intransitive), from Old French relier "assemble, put together; fasten, attach, rally, oblige," from Latin religare "fasten, bind fast," from re-, intensive prefix (see re-), + ligare "to bind" (see ligament). Sense of "depend, trust" is from 1570s, perhaps via notion of "rally to, fall back on." Typically used with on, perhaps by influence of lie (v.2). Related: Relied; relying.
wait (n.): early 13c., "a watcher, onlooker," from Old North French wait (Old French gait "look-out, watch, sentry"), from Old North French waitier (Old French gaitier; see wait (v.)).

From the sense "civic employee responsible for signaling the hour or an alarm by sounding on a trumpet, etc." comes the old sense "town musicians" (mid-15c.).
recline (v.): early 15c., from Old French recliner "rest, lay; bend, lean over" (13c.) and directly from Latin reclinare "to bend back, to lean back; cause to lean," from re- "back, against" (see re-) + clinare "to bend," from PIE *klei-n-, suffixed form of *klei "to lean" (see lean (v.)). Related: Reclined; reclining.
Recline is always as strong as lean, and generally stronger, indicating a more completely recumbent position, and approaching lie. [Century Dictionary]
big (adj.): c. 1300, northern England dialect, "powerful, strong," of obscure origin, possibly from a Scandinavian source (compare Norwegian dialectal bugge "great man"). Old English used micel in many of the same senses. Meaning "of great size" is late 14c.; that of "grown up" is attested from 1550s. Sense of "important" is from 1570s. Meaning "generous" is U.S. colloquial by 1913.

Liebfraumilch (n.): German white wine, 1833, from German, literally "milk of Our Lady."

liege (adj.): c. 1300, of lords, "entitled to feudal allegiance and service," from Anglo-French lige (late 13c.), Old French lige "liege-lord," noun use of an adjective meaning "free, giving or receiving fidelity" (corresponding to Medieval Latin ligius, legius), a word of uncertain origin. Perhaps from Late Latin laeticus "cultivated by serfs," from laetus "serf," which probably is from Proto-Germanic *lethiga- "freed" (source also of Old English læt "half-freedman, serf;" Old High German laz, Old Frisian lethar "freedman;" Middle Dutch ledich "idle, unemployed"), from PIE root *le- (2) "let go, slacken" (see let (v.)). Or the Middle English word might be directly from Old High German leidig "free," on the notion of "free from obligation to service except as vassal to one lord," but this reverses the notion contained in the word.

From late 14c. of vassals, "bound to render feudal allegiance and service." The dual sense of the adjective reflects the reciprocal relationship it describes: protection in exchange for service. Hence, liege-man "a vassal sworn to the service and support of a lord, who in turn is obliged to protect him" (mid-14c.).
lief (adv.): "dearly, gladly, willingly" (obsolete or archaic), c. 1250, from Middle English adjective lief "esteemed, beloved, dear," from Old English leof "dear, valued, beloved, pleasant" (also as a noun, "a beloved person, friend"), from Proto-Germanic *leubo- (source also of Old Norse ljutr, Old Frisian liaf, Dutch lief, Old High German liob, German lieb, Gothic liufs "dear, beloved"), from PIE root *leubh- "to love, care, desire" (see love (n.)).

Often with the dative and in personal constructions with have or would in expressions of choice or preference (and yet, to say the truth, I had as lief have the foppery of freedom, as the morality of imprisonment; "Measure for Measure"). I want and I'd love to are overworked and misused to fill the hole left in the language when I would lief faded in 17c.
liege (n.): late 14c., "vassal of a feudal lord," also "a feudal sovereign, a liege-lord," probably from liege (adj.)) or from a noun use of the adjective in Old French or Anglo-French. A fully reciprocal relationship, so the adjective could apply to either party. Old French distinguished them as lige seignur "liege-lord" and home lige "liege-man."
lien (n.): "right to hold property of another until debt is paid," 1530s, from Middle French lien "a band or tie" (12c.), from Latin ligamen "bond," from ligare "to bind, tie" (see ligament). The word was in Middle English in the literal sense "a bond, fetter," also figuratively, "moral restraint."
lied (n.): "German romantic song," 1852, from German Lied (plural Lieder), literally "song," from Middle High German liet, from Old High German liod, from Proto-Germanic *leuthan, from a PIE echoic root (see laud).

lieno-: word-forming element meaning "spleen, pertaining to the spleen, spleen and," from Latin lien "spleen" (see spleen).

Specific military sense of "army officer next in rank to a captain and commanding the company in his absence" is from 1570s. Pronunciation with lef- is common in Britain, and spellings to reflect it date back to 14c., but the origin of this is a mystery (OED rejects suggestion that it comes from old confusion of -u- and -v-).
lieu (n.): late 13c., usually as part of the phrase in lieu of "in the place, room, or stead of," from Old French lieu, lou "place, position, situation, rank" (10c.) from Latin locum (nominative locus) "place" (see locus).
lieutenancy (n.): "office or authority of a lieutenant," mid-15c., from lieutenant + -cy.
libation (n.): late 14c., "pouring out of wine in honor of a god," from Latin libationem (nominative libatio) "a drink-offering," noun of action from past participle stem of libare "pour out (an offering)," from PIE *(s)leib- "to pour, drop" (source of Greek leibein "to pour, make a libation").

This is from an enlargement of the PIE root *lei- "to flow" (source also of Sanskrit riyati "to let run;" Greek aleison "a cup for wine, goblet;" Lithuanian lieju "to pour," lytus "rain;" Hittite lilai- "to let go;" Albanian lyse, lise "a stream;" Welsh lliant "a stream, a sea," llifo "to flow;" Old Irish lie "a flood;" Breton livad "inundation;" Gaelic lighe "a flood, overflow;" Gothic leithu "fruit wine;" Old Church Slavonic liti, lêju, Bulgarian leja "I pour;" Czech liti, leji, Old Polish lić "to pour").

As a surname, originally with reference to fair hair or complexion, it is one of the oldest in English, being well-established before the Conquest. Meaning "morally pure" was in Old English. Association with royalist causes is late 18c. Slang sense of "honorable, fair" is 1877, American English; in Middle English it meant "gracious, friendly, favorable." The racial sense "of those races (chiefly European or of European extraction) characterized by light complexion" is recorded from c. 1600; meaning "characteristic of or pertaining to white people" is from 1852, American English.
