Middle English spelling of load (n.) "a burden," it keeps most of the word's original meaning "a way, a course, something to be followed."

"a way, a course, something to be followed" (a Middle English variant spelling of load (n.) that preserved the original Old English sense of that noun) + star (n.). Figurative use from late 14c. Compare lodestone. Similar formation in Old Norse leiðarstjarna, German Leitstern, Danish ledestjerne.ETD lodestar (n.).2

lodestone (n.)

lodge (n.)

Middle English logge, mid-13c. in surnames and place names; late 13c. as "small building or hut," from Old French loge "arbor, covered walk; hut, cabin, grandstand at a tournament" (12c.), from Frankish *laubja "shelter" (cognate with Old High German louba "porch, gallery," German Laube "bower, arbor"), from Proto-Germanic *laubja- "shelter." On a widespread guess (backed by Watkins, OED) this likely originally meant "shelter of foliage," or "roof made from bark," and is from the same PIE root as leaf (n.).ETD lodge (n.).2

Modern spelling is from c. 1500. The specific sense "hunter's cabin" is first recorded late 14c. Sense of "local branch of a society" is first recorded 1680s, of Freemasons, from an earlier use of lodge as "workshop of a group of masons" (mid-14c.). In the New World the word was used of certain American Indian buildings (1805), hence lodge-pole (1805) and lodge-pole pine (1859).ETD lodge (n.).3

lodging (n.)

early 14c., "encampment;" late 14c., "temporary accommodation; place of residence," verbal noun from lodge (v.). Related: Lodgings.ETD lodging (n.).2

lodge (v.)

c. 1200, loggen, "to encamp (an army), set up camp;" c. 1300 "furnish with a temporary habitation, put in a certain place," from Old French logier "to lodge; find lodging for" (12c., Modern French loger), from loge "hut, cabin" (see lodge (n.)).ETD lodge (v.).2

From late 14c. as "to dwell, live; to have temporary accommodations; to provide (someone) with sleeping quarters; to get lodgings." Sense of "plant, implant, get (a spear, bullet, fist, etc.) in the intended place, to make something stick" is from 1610s. Meaning "deposit" (a complaint, etc.) with an official" is from 1708.

If this is correct, the sense development would be from "loft, ceiling" to "sky, air." Buck suggests a further connection with Old High German louft "bark," louba "roof, attic," etc., with development from "bark" to "roof made of bark" to "ceiling," though this did not directly inform the meaning "air, sky" (compare lodge (n.)). But Watkins says this is "probably a separate Germanic root." Meaning "gallery in a church" first attested c. 1500. From 1520s as "apartment over a stable" used for hay storage, etc.ETD loft (n.).3

loft (v.)

"to hit a ball high in the air," 1856, originally in golf, from loft (n.). Compare sky (v.) in the modern slang sense. An earlier sense was "to put a loft on" (a building), 1560s; also "to store (goods) in a loft" (1510s). Related: Lofted; lofting.ETD loft (v.).2

log (n.1)

unshaped large piece of tree, early 14c., of unknown origin. Old Norse had lag "felled tree" (from stem of liggja "to lie," hence "a tree that lies prostrate"), but many etymologists deny on phonological grounds that this can be the root of English log. Instead, they suggest an independent formation meant to "express the notion of something massive by a word of appropriate sound" [OED, which compares clog (n.) in its original Middle English sense "lump of wood"].ETD log (n.1).2

Log cabin (1770) was the typical dwelling of the poor in antebellum U.S. history in the well-timbered region that was then the West. It has been a figure of the honest pioneer since the 1840 presidential campaign of William Henry Harrison (the original application was derisive and either way it was inaccurate).

log (n.2)

"record of observations, readings, etc.," originally "record of a ship's progress," 1842, sailor's shortening of log-book (1670s), the daily record of a ship's speed, progress, etc., which is from log (n.1) "piece of wood." The book so called because it recorded the speed measurements made by means of a weighted chip of a tree log on the end of a reeled log line (typically 150 to 200 fathoms). The log lay dead in the water, and sailors counted the time it took the line to play out. The line was marked by different numbers of knots, or colored rags, tied at regular intervals; hence the nautical measurement sense of knot (n.). Similar uses of the cognate word are continental Germanic and Scandinavian (such as German Log). General sense "any record of facts entered in order" is by 1913.ETD log (n.2).2

The native word was Old English lendenu "loins," from Proto-Germanic *landwin- (source also of German Lende "loin," Lenden "loins;" Old High German lenti, Old Saxon lendin, Middle Dutch lendine, Dutch lende, Old Norse lend). The Latin word perhaps was borrowed from Germanic.

fem. proper name, diminutive of Lola (thus a double diminutive). Title and character name in the 1958 novel by Vladimir Nabokov (1899-1977) "about a precocious schoolgirl seduced by a middle-aged man" [OED]; hence figurative use (by 1960) "to designate people and situations resembling those in the book."ETD Lolita.2

The doll-like Japanese fashion is mentioned in English circa 1995; the reference is ultimately derived from the Nabokov book, but in Japan the term had evolved a sense of "babyfaced adult" or "physically underdeveloped adult" and so became applied to the fashion style which tends to eschew any clothing elements traditionally seen as erotic or sexualized in favor of appearing cute and innocent.ETD Lolita.3

loll (v.)

mid-14c., lollen "to lounge idly, hang loosely;" late 14c., "rest at ease" (intransitive), a word of uncertain origin; perhaps related to Middle Dutch lollen "to doze, mumble," or somehow imitative of rocking or swinging.

name for certain heretics, late 14c., also Loller, from Middle Dutch lollaerd, a word applied pejoratively to members of semi-monastic reforming sects active in the Low Countries from c. 1300 who devoted themselves to the care of the sick and poor. The Dutch word means literally "mumbler, mutterer, one who mutters prayers and hymns," from lollen "to mumble or doze."ETD Lollard.2

lollipop (n.)

1784, lolly-pops "soft candy, coarse sweetmeat made of treacle and sugar, usually with butter and flour added," a word "of obscure formation" [OED]. The elements are perhaps related to loll (v.)

Meaning "hard candy on a stick" is from 1920s.ETD lollipop (n.).2

lollygag (v.)

Lombard (n.)

also (reflecting a variant pronunciation) Lumbard, late 15c., "native or inhabitant of Lombardy" in Italy, from Medieval Latin Lombardus (source also of Italian Lombardo), from Late Latin Langobardus, name of a Germanic people that originated in Scandinavia, migrated to the Elbe area 1c. C.E., then to Pannonia (5c.) and c. 568 under Albonius conquered northern Italy and founded a kingdom there.ETD Lombard (n.).2

The name is from Proto-Germanic *Langgobardoz, often said to mean literally "Long-beards" (see long (adj.) + beard (n.)), but according to OED the second element is perhaps rather from the proper name of the people (Latin Bardi). Their name in Old English was Langbeardas (plural), but also Heaðobeardan, from heaðo "war."ETD Lombard (n.).3

In Middle English the word meant "banker, money-changer, pawnbroker" (late 14c.), especially a Lombard or other Italian trading locally, before it was used in reference to the nationality. The name in Old French (Lombart, Lombert) also meant, in addition, "money-changer; usurer; coward." Lombards were noted throughout medieval Western Europe as bankers and money-lenders, also pawn-brokers. French also gave the word in this sense to Middle Dutch and Low German.ETD Lombard (n.).4

London's Lombard Street (c. 1200) originally was the site of the houses of Lombard (and other Italian) bankers, who dominated the London money-market into Elizabethan times.

Its mythical history is told in Layamon's "Brut" (c. 1200).ETD London.2

long (adj.)

The Germanic words perhaps are from PIE *dlonghos- (source also of Latin longus "long, extended; further; of long duration; distant, remote," Old Persian darga-, Persian dirang, Sanskrit dirghah "long"), from root *del- (1) "long" (source also of Greek dolikhos "long," endelekhes "perpetual"). Latin longus (source of prolong, elongate, longitude, etc.) thus is probably cognate with, but not the source of, the Germanic words. The word illustrates the Old English tendency for short "a" to become short "o" before -n- (also retained in bond/band and West Midlands dialectal lond from land and hond from hand).ETD long (adj.).3
