absoluteyoudaoicibaDictYouDict[absolute 词源字典]
absolute: [14] Absolute, absolution, and absolve all come ultimately from the same source: Latin absolvere ‘set free’, a compound verb made up from the prefix ab- ‘away’ and the verb solvere ‘loose’ (from which English gets solve and several other derivatives, including dissolve and resolve). From the 13th to the 16th century an alternative version of the verb, assoil, was in more common use than absolve; this came from the same Latin original, but via Old French rather than by a direct route.

The t of absolute and absolution comes from the past participial stem of the Latin verb – absolūt-. The noun, the adjective, and the verb have taken very different routes from their common semantic starting point, the notion of ‘setting free’: absolve now usually refers to freeing from responsibility and absolution to the remitting of sins, while absolute now means ‘free from any qualification or restriction’.

emancipateyoudaoicibaDictYouDict
emancipate: [17] Despite modern associations with women’s liberation, emancipate has no etymological connection with man. It comes from Latin ēmancipāre, which meant originally ‘free from parental power’. This was a compound verb formed from the prefix ex- ‘out of’ and mancipium ‘ownership’, and referred in Roman law to the freeing of a son from the legal authority of the male head of the family, thus making him responsible for himself in law. Mancipium (source of the archaic English noun manciple ‘steward, purveyor’ [13]) was ultimately a compound noun formed from manus ‘hand’ (as in English manual) and capere ‘take’ (as in English captive and capture).

The association of the verb with the ‘freeing of slaves’, the basis of the present English meanings, is a modern development.

=> captive, capture, manciple, manual
immuneyoudaoicibaDictYouDict
immune: [15] The -mune of immune is the same as that of remunerate and of commune (and hence of common). It represents Latin mūnis ‘ready to give service’. The addition of the negative prefix in- gave immūnis, which in classical Latin denoted literally ‘exempt from a service, charge, etc’, and hence by metaphorical extension ‘free from something, devoid of something’. This general sense still survives, of course, in English (as in ‘grant immunity from prosecution’); and the more specific ‘not liable to infection’ did not emerge until as recently as the 1870s, probably under the influence of French or German.
=> common, commune, remunerate
netyoudaoicibaDictYouDict
net: English has two distinct words net. The commoner and more ancient, ‘mesh’ [OE], is a widespread Germanic word: German has the related netz, Dutch and Danish net, and Swedish nät. Its ultimate origins are not known, although a link with Latin nassa ‘wicker basket for catching fish’ has been suggested. Net ‘without deductions’ [14] comes from French net, which was borrowed into English again two centuries later as neat.

It was originally used, like its French source, for ‘trim, clean’, but this developed via ‘unadulterated, unmixed’ to, by the early 16th century, ‘free from any (further) deduction’. The alternative spelling nett dates from the 16th century.

=> neat
secureyoudaoicibaDictYouDict
secure: [16] Something that is secure is etymologically ‘carefree’. The word was borrowed from Latin sēcūrus, a compound adjective formed from the prefix - ‘without’ and cūra ‘care’ (source of English curate, cure, etc). The metaphorical extension from ‘free from care’ to ‘free from danger, safe’ took place in post-Augustan Latin. Sure is in effect a telescoped version of secure.
=> curate, cure, sure

late 14c., from Latin Æthiops "Ethiopian, negro," from Greek Aithiops, long supposed in popular etymology to be from aithein "to burn" + ops "face" (compare aithops "fiery-looking," later "sunburned").
Who the Homeric Æthiopians were is a matter of doubt. The poet elsewhere speaks of two divisions of them, one dwelling near the rising, the other near the setting of the sun, both having imbrowned visages from their proximity to that luminary, and both leading a blissful existence, because living amid a flood of light; and, as a natural concomitant of a blissful existence, blameless, and pure, and free from every kind of moral defilement. [Charles Anthon, note to "The First Six Books of Homer's Iliad," 1878]

The meaning in reference to weather preserves the oldest sense "suitable, agreeable" (opposed to foul (adj.)). Of the main modern senses of the word, that of "light of complexion or color of hair and eyes, not dusky or sallow" (of persons) is from c. 1200, faire, contrasted to browne and reflecting tastes in beauty. From early 13c. as "according with propriety; according with justice," hence "equitable, impartial, just, free from bias" (mid-14c.).

The sporting senses (fair ball, fair catch, etc.) began to appear in 1856. Fair play is from 1590s but not originally in sports. Fair-haired in the figurative sense of "darling, favorite" is from 1909. First record of fair-weather friends is from 1736 (in a letter from Pope published that year, written in 1730). The fair sex "women" is from 1660s, from the "beautiful" sense (fair as a noun meaning "a woman" is from early 15c.). Fair game "legitimate target" is from 1776, from hunting.

great (adj.)youdaoicibaDictYouDict
Old English great "big, tall, thick, stout, massive; coarse," from West Germanic *grautaz "coarse, thick" (cognates: Old Saxon grot, Old Frisian grat, Dutch groot, German groß "great"). If the original sense was "coarse," it is perhaps from PIE root *ghreu- "to rub, grind," but "the connextion is not free from difficulty" [OED]. It took over much of the sense of Middle English mickle, and itself now is largely superseded by big and large except in reference to non-material things.

In the sense of "excellent, wonderful" great is attested from 1848. Great White Way "Broadway in New York City" is from 1901, in reference to brilliant street illumination. The Great Lakes of North America so called from 1747. Great Spirit "high deity of the North American Indians," 1703, originally translates Ojibwa kitchi manitou. The Great War originally (1887) referred to the Napoleonic Wars, later (1914) to what we now call World War I (see world).
"The Great War" -- as, until the fall of France, the British continued to call the First World War in order to avoid admitting to themselves that they were now again engaged in a war of the same magnitude. [Arnold Toynbee, "Experiences," 1969]
Also formerly with a verb form, Old English greatian "to become enlarged," Middle English greaten "to become larger, increase, grow; become visibly pregnant," which became archaic after 17c.
hale (adj.)youdaoicibaDictYouDict

immaculate (adj.)youdaoicibaDictYouDict
early 15c., "free from mental or moral pollution, pure," from a figurative use of Latin immaculatus "unstained," from assimilated form of in- "not, opposite of" (see in- (1)) + maculatus "spotted, defiled," past participle of maculare "to spot," from macula "spot, blemish." The literal sense of "spotlessly clean or neat" in English is first attested 1735. Immaculate Conception is late 15c., from Middle French conception immaculée (late 15c.); declared to be an article of faith in 1854.
immune (adj.)youdaoicibaDictYouDict
mid-15c., "free; exempt," back-formation from immunity. Latin immunis meant "exempt from public service, free from taxes." Specific modern medical sense of "exempt from a disease" (typically because of inoculation) is from 1881. Immune system attested by 1917.
impassionate (adj.)youdaoicibaDictYouDict
"free from passion," 1620s, from in- (1) "not" + passionate. Related: Impassionately.
inculpate (v.)youdaoicibaDictYouDict
1799, "to accuse, bring charges against," from Medieval Latin inculpatus, past participle of inculpare "to reproach, blame, censure," from Latin in- "in" (see in- (2)) + culpare "to blame," from culpa "fault."

Meaning "free from guilt of a specific crime or charge" is from late 14c. The earliest use was as a noun, "person who is innocent of sin or evil" (c. 1200). The Holy Innocents (early 14c.) were the young children slain by Herod after the birth of Jesus (Matt. ii:16).
large (adj.)youdaoicibaDictYouDict
c. 1200, "bountiful, inclined to give or spend freely," also, of areas, "great in expanse," from Old French large "broad, wide; generous, bounteous," from Latin largus "abundant, copious, plentiful; bountiful, liberal in giving," of unknown origin. Main modern meanings "extensive; big in overall size" emerged 14c. An older sense of "liberated, free from restraining influence" is preserved in at large (late 14c.). Adjective phrase larger-than-life first attested 1937 (bigger than life is from 1640s).
liberal (adj.)youdaoicibaDictYouDict
mid-14c., "generous," also, late 14c., "selfless; noble, nobly born; abundant," and, early 15c., in a bad sense "extravagant, unrestrained," from Old French liberal "befitting free men, noble, generous, willing, zealous" (12c.), from Latin liberalis "noble, gracious, munificent, generous," literally "of freedom, pertaining to or befitting a free man," from liber "free, unrestricted, unimpeded; unbridled, unchecked, licentious," from PIE *leudh-ero-, probably originally "belonging to the people" (though the precise semantic development is obscure; compare frank (adj.)), and a suffixed form of the base *leudh- "people" (cognates: Old Church Slavonic ljudu, Lithuanian liaudis, Old English leod, German Leute "nation, people;" Old High German liut "person, people").

With the meaning "free from restraint in speech or action," liberal was used 16c.-17c. as a term of reproach. It revived in a positive sense in the Enlightenment, with a meaning "free from prejudice, tolerant," which emerged 1776-88.

In reference to education, explained by Fowler as "the education designed for a gentleman (Latin liber a free man) & ... opposed on the one hand to technical or professional or any special training, & on the other to education that stops short before manhood is reached" (see liberal arts). Purely in reference to political opinion, "tending in favor of freedom and democracy" it dates from c. 1801, from French libéral, originally applied in English by its opponents (often in French form and with suggestions of foreign lawlessness) to the party favorable to individual political freedoms. But also (especially in U.S. politics) tending to mean "favorable to government action to effect social change," which seems at times to draw more from the religious sense of "free from prejudice in favor of traditional opinions and established institutions" (and thus open to new ideas and plans of reform), which dates from 1823.
Conservative, n. A statesman who is enamored of existing evils, as distinguished from the Liberal, who wishes to replace them with others. [Ambrose Bierce, "Devil's Dictionary," 1911]

Meaning "not clinging, slack" is mid-15c. Meaning "not bundled" is late 15c. Sense of "unchaste, immoral" is recorded from late 15c. Meaning "at liberty, free from obligation" is 1550s. Sense of "rambling, disconnected" is from 1680s. Figurative sense of loose cannon was in use by 1896, probably from celebrated image in a popular story by Hugo:
You can reason with a bull dog, astonish a bull, fascinate a boa, frighten a tiger, soften a lion; no resource with such a monster as a loose cannon. You cannot kill it, it is dead; and at the same time it lives. It lives with a sinister life which comes from the infinite. It is moved by the ship, which is moved by the sea, which is moved by the wind. This exterminator is a plaything. [Victor Hugo, "Ninety Three"]
