c. 1300, "giving light, shining, luminous;" also "not turbid; transparent, allowing light to pass through; free from impurities; morally pure, guiltless, innocent;" of colors, "bright, pure;" of weather or the sky or sea, "not stormy; mild, fair, not overcast, fully light, free from darkness or clouds;" of the eyes or vision, "clear, keen;" of the voice or sound, "plainly audible, distinct, resonant;" of the mind, "keen-witted, perspicacious;" of words or speech, "readily understood, manifest to the mind, lucid" (an Old English word for this was sweotol "distinct, clear, evident"); of land, "cleared, leveled;" from Old French cler "clear" (of sight and hearing), "light, bright, shining; sparse" (12c., Modern French clair), from Latin clarus "clear, loud," of sounds; figuratively "manifest, plain, evident," in transferred use, of sights, "bright, distinct;" also "illustrious, famous, glorious" (source of Italian chiaro, Spanish claro), from PIE *kle-ro-, from root *kele- (2) "to shout."

The prehistoric sense evolution to light and color involves an identification of the spreading of sound and the spreading of light (compare English loud, used of colors; German hell "clear, bright, shining," of pitch, "distinct, ringing, high").

Also in Middle English "beautiful, magnificent, excellent" (c. 1300); of possession or title, "unrestricted, unconditional, absolute," early 15c. Of complexion, from c. 1300. Sense of "free from encumbrance," later largely nautical, developed c. 1500. Meaning "obvious to the senses" is from 1835. Clear-sighted is from 1580s (clear-eyed is from 1520s); clear-headed is from 1709. For coast is clear see clear (v.).

"a bay, cove, inlet, or recess of a large body of water where vessels can load and unload and find shelter from storms; a harbor, whether natural or artificial," Old English port "a port, harbor, a place where there is a constant resort of vessels for the purpose of loading and unloading;" also "a town, market town, city," reinforced by Old French port "harbor, port; mountain pass." The Old English and Old French words both are from Latin portus "a port, harbor," figuratively "haven, place of refuge, asylum" (in Old Latin also "a house;" in Late Latin also "a warehouse"), originally "an entrance, a passage," akin to porta "a city gate, a gate, a door" (from PIE *prtu- "a going, a passage," suffixed form of root *per- (2) "to lead, pass over").

[I]in law, a place where persons and merchandise are allowed to pass into and out of the realm and at which customs officers are stationed for the purpose of inspecting or appraising imported goods. In this sense a port may exist on the frontier, where the foreign communication is by land. [Century Dictionary]

The figurative sense "place, position, or condition of refuge" is attested in English from early 15c.; phrase any port in a storm, indicating "any refuge is welcomed in adversity," is by 1749. A port of call (1810) is one paid a scheduled visit by a vessel in the course of its voyage. The verb meaning "to carry or bring into a port" is by 1610s.

mid-15c., "the tilling of land, act of preparing the earth for crops," from Latin cultura "a cultivating, agriculture," figuratively "care, culture, an honoring," from past participle stem of colere "to tend, guard; to till, cultivate" (see colony). Meaning "the cultivation or rearing of a crop, act of promoting growth in plants" (1620s) was transferred to fish, oysters, etc., by 1796, then to "production of bacteria or other microorganisms in a suitable environment" (1880), then "product of such a culture" (1884).

The figurative sense of "cultivation through education, systematic improvement and refinement of the mind" is attested by c. 1500; Century Dictionary writes that it was, "Not common before the nineteenth century, except with strong consciousness of the metaphor involved, though used in Latin by Cicero." Meaning "learning and taste, the intellectual side of civilization" is by 1805; the closely related sense of "collective customs and achievements of a people, a particular form of collective intellectual development" is by 1867.

For without culture or holiness, which are always the gift of a very few, a man may renounce wealth or any other external thing, but he cannot renounce hatred, envy, jealousy, revenge. Culture is the sanctity of the intellect. [William Butler Yeats, journal, 7 March, 1909]

Slang culture vulture "one voracious for culture" is from 1947. Culture shock "disorientation experienced when a person moves to a different cultural environment or an unfamiliar way of life" is attested by 1940. Ironic or contemptuous spelling kulchur is attested from 1940 (Pound), and compare kultur.

late 14c., "free choice, freedom to do as one chooses," also "freedom from the bondage of sin," from Old French liberte "freedom, liberty, free will" (14c., Modern French liberté), from Latin libertatem (nominative libertas) "civil or political freedom, condition of a free man; absence of restraint; permission," from liber "free" (see liberal (adj.)). At first of persons; of communities, "state of being free from arbitrary, despotic, or autocratic rule or control" is by 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. The meaning "unrestrained action, conduct, or expression" (1550s) led to take liberties "go beyond the bounds of propriety" (1620s). The sense of "privileges by grant" (14c.) led to the 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.

c. 1200 (late 12c. in place names and surnames), "an unmarried woman (usually young); the Virgin Mary;" shortening of maiden (n.). Like that word, used in Middle English of unmarried men as well as women (as in maiden-man, c. 1200, which was used of both sexes, reflecting also the generic use of man).

From c. 1300 as "a virgin," also as "maidservant, female attendant, lady in waiting." By c. 1500 this had yielded the humbler sense of "female servant or attendant charged with domestic duties." Often with a qualifying word (housemaid, chambermaid, etc.); maid of all work "female servant who performs general housework" is by 1790.

Her Mamma was a famous Fryer of Fishes,

Squeezer of Mops, Washer of Dishes,

From tossing of Pancakes would not Shirk,

In English plain, a Maid of all Work.

But don't mistake me, by Divinity,

When I mention Maid, I don't mean Virginity 

[from "Countess of Fame and her Trumpeter," 1793]

In reference to Joan of Arc, attested from 1540s (French la Pucelle). Maid Marian, the Queen of the May in the morris dances, also one of Robin Hood's companions, is recorded by 1520s, perhaps from French, where Robin et Marian have been stock names for country lovers since 13c. Maid of Honor (1580s) originally was "unmarried lady of noble birth who attends a queen or princess;" meaning "principal bridesmaid" is attested from 1895. Maydelond (translating Latin terra feminarum) was "the land of the Amazons."

Old English elles "in another manner, other, otherwise, besides, different," from Proto-Germanic *aljaz (source also of Gothic aljis "other," Old High German eli-lenti, Old English el-lende, both meaning "in a foreign land;" see also Alsace), an adverbial genitive of the neuter of PIE root *al- "beyond" (source also of Greek allos "other," Latin alius). As a quasi-adjective, synonymous with other, from 1660s; the nuances of usage are often arbitrary.

Productive of a number of handy compounds that somehow never got traction or have been suffered to fall from use: elsehow (1660s) "somehow or other;" elsewards (adv.), 1882, "somewhere else;" Old English elsewhat (pron.) "something else, anything else;" elsewhen (adv.), early 15c., "at another time; elsewhence (c. 1600); elsewho (1540s). Among the survivors are elsewhere, elsewise. Menacing or else, with omitted but implied threat, is implied by 1814:

In Tynedale, Buccleuch seized upon no less than thirty-six English freebooters, and put them to death without mercy. The wrath of Elizabeth waxed uncontrollable. "I marvel," are her own royal expressions, "how the king thinks me so base-minded as to sit down with such dishonourable treatment. Let him know we will be satisfied, or else"—Some of James's ancestors would have bid her

"Choke in thy threat. We can say or as loud."

[Sir Walter Scott, "The Border Antiquities of England and Scotland," 1814]

early 12c., "a meeting at a fixed time for buying and selling livestock and provisions, an occasion on which goods are publicly exposed for sale and buyers assemble to purchase," from Old North French market "marketplace, trade, commerce" (Old French marchiet, Modern French marché), from Latin mercatus "trading, buying and selling; trade; market" (source of Italian mercato, Spanish mercado, Dutch markt, German Markt), from past participle of mercari "to trade, deal in, buy," from merx (genitive mercis) "wares, merchandise." This is from an Italic root *merk-, possibly from Etruscan, referring to various aspects of economics.

The god Mercurius was probably the god of exchange. According to [Walde-Hoffmann], the god's name was borrowed from Etruscan; in principle, the same is possible for the stem *merk- altogether. [de Vaan]

Meaning "public building or space where markets are held" is attested from late 13c. Meaning "a city, country or region considered as a place where things are bought or sold" is from 1610s. Sense of "sale as controlled by supply and demand" is from 1680s. Market-garden "plot of land on which vegetables are grown for market" is by 1789. Market-basket "large basket used to carry marketing" is by 1798. Market price "price a commodity will bring when sold in open market" is from mid-15c.; market value "value established or shown by sales" (1690s) is first attested in the writings of John Locke. Market economy is from 1948; market research is from 1921.

early 14c., brasile, "brasilwood," name of a type of red wood from an East Indian tree, used in making dye (in modern times known as sappan-wood or Indian redwood), from Medieval Latin brasilium, Old French bresil, which probably is related to brese "embers," and like it from a Germanic source (compare braze (v.1)), from PIE root *bhreu- "to boil, bubble, effervesce, burn," and so called for resemblance of color to a glowing ember.

But as the product came to Europe via India perhaps this is a folk-etymology of some word in Arabic or another Asian language (an Old Italian form, verzino, suggests to some a possible connection with Arabic wars "saffron"). The same word for the same stuff entered Portuguese and Spanish (brasil) and Italian (brasile).

The South American country was named Santa Cruz by its "discoverer," Pedro Alvarez Cabral (1500), but within a decade on maps it began to be called terra de brasil "red-dyewood land" because it produced a valuable red dyewood similar to East Indian type, and that name predominated from 1550s.

Complicating matters is Hy Brasil, a name attested since early 14c. for a legendary island or rock in the North Atlantic off the west coast of Ireland. It is so-called perhaps from the "red dyewood" word by association with Pliny's Insulae Purpurariae ("Purple Islands") in the Atlantic off the coast of Morocco.

"medieval chemistry; the supposed science of transmutation of base metals into silver or gold" (involving also the quest for the universal solvent, quintessence, etc.), mid-14c., from Old French alchimie (14c.), alquemie (13c.), from Medieval Latin alkimia, from Arabic al-kimiya, from Greek khemeioa (found c.300 C.E. in a decree of Diocletian against "the old writings of the Egyptians"), all meaning "alchemy," and of uncertain origin.

Perhaps from an old name for Egypt (Khemia, literally "land of black earth," found in Plutarch), or from Greek khymatos "that which is poured out," from khein "to pour," from PIE root *gheu- "to pour" [Watkins, but Klein, citing W. Muss-Arnolt, calls this folk etymology]. The word seems to have elements of both origins.

Mahn ... concludes, after an elaborate investigation, that Gr. khymeia was probably the original, being first applied to pharmaceutical chemistry, which was chiefly concerned with juices or infusions of plants; that the pursuits of the Alexandrian alchemists were a subsequent development of chemical study, and that the notoriety of these may have caused the name of the art to be popularly associated with the ancient name of Egypt. [OED]

The al- is the Arabic definite article, "the." The art and the name were adopted by the Arabs from Alexandrians and entered Europe via Arabic Spain. Alchemy was the "chemistry" of the Middle Ages and early modern times, involving both occult and natural philosophy and practical chemistry and metallurgy. After c. 1600 the strictly scientific sense went with chemistry, and alchemy was left with the sense "pursuit of the transmutation of baser metals into gold, search for the universal solvent and the panacea."

large province of eastern Canada, probably from Portuguese Lavrador, which is of uncertain origin. Among the theories advanced, W.F. Ganong identifies as "The generally accepted and altogether probable one" that "it was originally 'Terra Laboratoris,' land of the laborer because Cortereal brought fifty men thence to Europe, who were described as well fitted for slaves. This is sustained by all the evidence of old maps." Gasper Cortereal was a Portuguese navigator who explored the coast for the Portuguese crown in 1500 and brought home captives. He returned for more in 1501, but was never heard from again. But a Portuguese map of 1520 has the name Lavrador applied to Greenland, while the coast of Labrador and Newfoundland is called Bacalhaos, which is "codfish" in Basque.

[Labrador] is not used in Cartier's narratives, though it appears in the title of the 1598 edition of his first narrative. It is supposed to have been added by the translator. There are, at least, six theories as to the origin of this word. [W.F. Ganong, "The Cartography of the Gulf of St. Lawrence," 1887] 

One of them [Room] is that the sense of the name is "landholder" and is a reference to 15c. Portuguese explorer João Fernandes, called Llavrador, who was a landholder in the Azores and had sailed as far as Iceland and Greenland. John Cabot met Fernandes when he was in Spain and Portugal in the spring of 1498, recruiting sailors for an Atlantic voyage, and he advised Cabot that this was a good way to get to Asia. The breed of retriever dog so called from 1815. Related: Labradorian.
