Q
Q — quarter (n.2)
16th letter of the classical Roman alphabet, occurring in English only before a -u- that is followed by another vowel (with a few exceptions; see below), whether the -u- is sounded or not (pique). The letter is from the Phoenician equivalent of Hebrew koph, qoph, which was used for the deeper and more guttural of the two "k" sounds in Semitic. The letter existed in early Greek (where there was no such distinction), and called koppa, but it was little used and not alphabetized; it mainly served as a sign of number (90).ETD Q.2
The connection with -u- began in Latin. Anglo-Saxon scribes at first adopted the habit, but later used spellings with cw- or cu-. The qu- pattern returned to English with the Normans and French after the Conquest and had displaced cw- by c. 1300.ETD Q.3
In some spelling variants of late Middle English, quh- also took work from wh-, especially in Scottish and northern dialects, for example Gavin Douglas, Provost of St. Giles, in his vernacular "Aeneid" of 1513:ETD Q.4
Scholars use -q- alone to transliterate Semitic koph or the equivalent in Turkish or Iranian (as in Quran, Qatar, Iraq). In Christian theology, Q has been used since 1901 to signify the hypothetical source of passages shared by Matthew and Luke but not in Mark; in this sense probably it is an abbreviation of German Quelle "source" (from Old High German quella, from the same Proto-Germanic source as Old English cwiella, cwylla "spring; well"). In Middle English accounts, it is an abbreviation of quadrans "farthing" (mid-15c.). In Roman personal names it is an abbreviation of Quintus.ETD Q.5
also Q & A, 1954 (adj.), abbreviation of question and answer (itself attested by 1817 as a noun, by 1839 as an adjective).ETD Q and A.2

It revived in a narrower sense in American English in reference to stalled military actions, 1965, with reference to the U.S. war in Vietnam (popularized in the book title "The Making of a Quagmire" by David Halberstam).ETD quagmire (n.).3
"large, edible, round clam of the Atlantic Coast of the U.S.," much used for soups and chowders, by 1753 in roughly the modern spelling (quogue; Roger Williams had it as poquauhock, 1643), from an Algonquian language, perhaps Narragansett poquauhock or Pequot p'quaghhaug "hard clam."ETD quahog (n.).2

In a French context it is often short for Quai d'Orsay, the street on the south bank of the Seine in Paris, since mid-19c. site of the French Ministry of Foreign Affairs and hence sometimes used metonymically for it (by 1922).ETD quai (n.).2
"landing place, place where vessels are loaded and unloaded, a wharf," 1690s, a spelling variant of Middle English key, keye, caye "wharf" (c. 1300; mid-13c. in place names), from Old North French cai (Old French chai, 12c., Modern French quai) "sand bank," from Gaulish caium (5c.), from Old Celtic *kagio- "to encompass, enclose" (source also of Welsh cae "fence, hedge," Cornish ke "hedge"), from PIE root *kagh- "to catch, seize; wickerwork, fence" (see hedge (n.)).

c. 1200, cointe, cwointe, "cunning, artful, ingenious; proud," in both good and bad senses, from Old French cointe, queinte "knowledgeable, well-informed; clever; arrogant, proud; elegant, gracious," from Latin cognitus "known, approved," past participle of cognoscere "get or come to know well" (see cognizance). Modern spelling is from early 14c. (see Q).ETD quaint (adj.).2
The old senses all are archaic or obsolete. Perhaps the fuzziness of the good and bad senses in the word contributed to this. Compare Middle English queintise (n.) "wisdom, knowledge," also "guile, cunning, deceit" (c. 1300).ETD quaint (adj.).3
Later in English, quaint came to mean "elaborate, skillfully made" (c. 1300); "strange and clever, fanciful, odd whimsical" (mid-14c.).

Perhaps somehow imitative (compare quag, quaver, quiver (v.), Middle English quaven "tremble, shake, palpitate," c. 1200). Related: Quaked; quaking. In Middle English formerly also with strong past-participle form quoke. The North American quaking aspen is so called by 1822.ETD quake (v.).2
"a member of the Christian denomination known as the Religious Society of Friends," 1651, said to have been applied to them in 1650 by Justice Bennett at Derby, from George Fox's admonition to his followers to "tremble at the Word of the Lord;" but the word was used earlier of foreign sects given to fits of shaking during religious fervor, and that is likely the source here. Either way, it never was an official name of the Religious Society of Friends.ETD Quaker (n.).2
The word in a literal sense of "one who or that which trembles" is attested from early 15c., an agent noun from quake (v.). The notion of "trembling" in religious awe is in Old English; quaking (n.) meaning "fear and reverence" especially in religion is attested from mid-14c.ETD Quaker (n.).3
Figuratively, as an adjective, in reference to plain or drab colors (such as were worn by members of the sect) is by 1775. A Quaker gun (1809, American English), originally a log painted black and propped up to resemble the barrel of a cannon to deceive the enemy from a distance, is so called for the sect's noted pacifism. Philadelphia, Pennsylvania, has been known as the Quaker City at least since 1824. Related: Quakerish; Quakeress ("a female Quaker"); Quakerism; Quakerdom; Quakerly.ETD Quaker (n.).4

Related: Qualifications.ETD qualification (n.).2
"one who or that which qualifies" in any sense, 1560s, agent noun from qualify. Grammatical sense of "a word that qualifies another, modifying or reducing the meaning of a noun, verb, etc." is from 1580s. The Church court office of qualificator is attested from 1680s.ETD qualifier (n.).2
mid-15c., qualifien, transitive, "to invest with (a quality), impart a certain quality to," from French qualifier (15c.) and directly from Medieval Latin qualificare "attribute a quality to; make of a certain quality," from Latin qualis "of what sort?," correlative pronominal adjective (see quality) + combining form of facere "to make" (from PIE root *dhe- "to set, put").ETD qualify (v.).2

early 15c., qualitatif, "that produces a (physical) quality," from Medieval Latin qualitativus "relating to quality," from stem of Latin qualitas "a quality, property, nature" (see quality).

Related: Qualitatively.ETD qualitative (adj.).2
c. 1300, qualite, "temperament, character, disposition," from Old French calite, qualite "quality, nature, characteristic" (12c., Modern French qualité), from Latin qualitatem (nominative qualitas) "a quality, property; nature, state, condition" (said [Tucker, etc.] to have been coined by Cicero to translate Greek poiotēs), from qualis "what kind of a" (from PIE root *kwo-, stem of relative and interrogative pronouns).ETD quality (n.).2
In early use, and for long thereafter, with awareness of the word's use in Aristotelian philosophy. From late 14c. as "an inherent attribute," also "degree of goodness or excellence."

Middle English, from Old English cwealm, cwelm (West Saxon) "death, murder, slaughter; disaster; widespread death by plague, pestilence or illness affecting humans or livestock; torment," utcualm (Anglian) "utter destruction," probably related to cwellan "to kill, murder, execute," cwelan "to die" (see quell).ETD qualm (n.).2
The sense softened to "feeling of faintness" (1520s); the figurative meaning "uneasiness, doubt" is from 1550s; that of "a scruple of conscience" is from 1640s. Evidence of a direct path from the Old English and Middle English senses (now obsolete) to the modern senses is wanting (OED 2nd edition has them as separate entries), and the old word seems to have become rare after c. 1400. But it is plausible, via the notion of "fit of sickness," and could have been influenced by queasy.ETD qualm (n.).3
The other suggested etymology, less satisfying, is that the "fit of uneasiness" sense is from Dutch kwalm "steam, vapor, mist" (cognate with German Qualm "smoke, vapor, stupor"), which also might be ultimately from the same Germanic root as quell.ETD qualm (n.).4
see qualm.ETD qualms (n.).2
"state of great difficulty or perplexity," 1570s, a word of unknown origin and even the pronunciation is unsettled in old dictionaries (it seems to have been originally accented on the second syllable).

"indulgence or mercy shown to a vanquished foe; exemption from being immediately killed upon being defeated in battle or armed contest," 1610s, presumably from quarter (n.1) or its French equivalent quartier in this meaning, but OED writes that "the precise origin of this sense is obscure ...."
