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.

frank (adj.)youdaoicibaDictYouDict
c. 1300, "free, liberal, generous;" 1540s, "outspoken," from Old French franc "free (not servile); without hindrance, exempt from; sincere, genuine, open, gracious, generous; worthy, noble, illustrious" (12c.), from Medieval Latin francus "free, at liberty, exempt from service," as a noun, "a freeman, a Frank" (see Frank).

A generalization of the tribal name; the connection is that Franks, as the conquering class, alone had the status of freemen in a world that knew only free, captive, or slave. For sense connection of "being one of the nation" and "free," compare Latin liber "free," from the same root as German Leute "nation, people" (see liberal (adj.)) and Slavic "free" words (Old Church Slavonic svobodi, Polish swobodny, Serbo-Croatian slobodan) which are cognates of the first element in English sibling "brother, sister" (in Old English used more generally: "relative, kinsman").
free (adj.)youdaoicibaDictYouDict
Old English freo "free, exempt from, not in bondage, acting of one's own will," also "noble; joyful," from Proto-Germanic *frija- "beloved; not in bondage" (cognates: Old Frisian fri, Old Saxon vri, Old High German vri, German frei, Dutch vrij, Gothic freis "free"), from PIE *priy-a- "dear, beloved," from root *pri- "to love" (cognates: Sanskrit priyah "own, dear, beloved," priyate "loves;" Old Church Slavonic prijati "to help," prijatelji "friend;" Welsh rhydd "free").

The primary Germanic sense seems to have been "beloved, friend, to love;" which in some languages (notably Germanic and Celtic) developed also a sense of "free," perhaps from the terms "beloved" or "friend" being applied to the free members of one's clan (as opposed to slaves; compare Latin liberi, meaning both "free persons" and "children of a family"). For the older sense in Germanic, compare Gothic frijon "to love;" Old English freod "affection, friendship, peace," friga "love," friðu "peace;" Old Norse friðr "peace, personal security; love, friendship," German Friede "peace;" Old English freo "wife;" Old Norse Frigg "wife of Odin," literally "beloved" or "loving;" Middle Low German vrien "to take to wife," Dutch vrijen, German freien "to woo."

Meaning "clear of obstruction" is from mid-13c.; sense of "unrestrained in movement" is from c. 1300; of animals, "loose, at liberty, wild," late 14c. Meaning "liberal, not parsimonious" is from c. 1300. Sense of "characterized by liberty of action or expression" is from 1630s; of art, etc., "not holding strictly to rule or form," from 1813. Of nations, "not subject to foreign rule or to despotism," recorded in English from late 14c. (Free world "non-communist nations" attested from 1950 on notion of "based on principles of civil liberty.") Sense of "given without cost" is 1580s, from notion of "free of cost."

Free lunch, originally offered in bars to draw in customers, by 1850, American English. Free pass on railways, etc., attested by 1850. Free speech in Britain was used of a privilege in Parliament since the time of Henry VIII. In U.S., in reference to a civil right to expression, it became a prominent phrase in the debates over the Gag Rule (1836). Free enterprise recorded from 1832; free trade is from 1823; free market from 1630s. Free will is from early 13c. Free school is from late 15c. Free association in psychology is from 1899. Free love "sexual liberation" attested from 1822 (the doctrine itself is much older), American English. Free and easy "unrestrained" is from 1690s.
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.
immunity (n.)youdaoicibaDictYouDict
late 14c., "exempt from service or obligation," from Old French immunité and directly from Latin immunitatem (nominative immunitas) "exemption from performing public service or charge," from immunis "exempt, free," from assimilated form of in- "not, opposite of" (see in- (1)) + munis "performing services" (compare municipal), from PIE *moi-n-es-, suffixed form of root *mei- (1) "to change" (see mutable). Medical sense "protection from disease" is 1879, from French or German.
impassible (adj.)youdaoicibaDictYouDict
"incapable of feeling pain, exempt from suffering," mid-14c., from Old French impassible (13c.), from Church Latin impassibilis "incapable of passion," from assimilated form of in- "not, opposite of" (see in- (1)) + passibilis, from passio "suffering" (see passion). Related: Impassibility.
scot-free (adj.)youdaoicibaDictYouDict
Old English scotfreo "exempt from royal tax," from scot "royal tax," from Old Norse skot "contribution," literally "a shooting, shot; thing shot, missile," from PIE *skeud- "to shoot, chase, throw" (see shoot (v.); the Old Norse verb form, skjota, has a secondary sense of "transfer to another; pay") + freo (see free (adj.)). First element related to Old English sceotan "to pay, contribute," Dutch schot, German Schoß "tax, contribution." French écot "share" (Old French escot) is from Germanic.
toleration (n.)youdaoicibaDictYouDict
1510s, "permission granted by authority, license," from Middle French tolération (15c.), from Latin tolerationem (nominative toleratio) "a bearing, supporting, enduring," noun of action from past participle stem of tolerare "to endure, sustain, support, suffer," literally "to bear," from PIE *tele- "to bear, carry" (see extol).

Meaning "forbearance, sufferance" is from 1580s. The specific religious sense is from 1609; as in Act of Toleration (1689), statute granting freedom of religious worship (with conditions) to dissenting Protestants in England. In this it means "recognition of the right of private judgment in matters of faith and worship; liberty granted by the government to preach and worship as one pleases; equality under the law without regard to religion."
If any man err from the right way, it is his own misfortune, no injury to thee; nor therefore art thou to punish him in the things of this life because thou supposest he will be miserable in that which is to come. Nobody, therefore, in fine, neither single persons nor churches, nay, nor even commonwealths, have any just title to invade the civil rights and worldly goods of each other upon pretence of religion. [John Locke, "Letter Concerning Toleration," 1689]



Before any man can be considered as a member of Civil Society, he must be considered as a subject of the Governour of the Universe: And if a member of Civil Society, do it with a saving of his allegiance to the Universal Sovereign. We maintain therefore that in matters of Religion, no man's right is abridged by the institution of Civil Society and that Religion is wholly exempt from its cognizance. [James Madison, "Memorial and Remonstrance Against Religious Assessments," 1785]



Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them. [Karl Popper, "The Open Society and Its Enemies," 1962]
