"to smile in an affected and silly way," 1560s, perhaps from a Scandinavian source (compare dialectal Danish semper "affected, coy, prudish") or Middle Dutch zimperlijk "affected, coy, prim," all of unknown origin. Related: Simpered; simpering. As a noun, "an affected smile," 1590s, from the verb.

Old English grennian "show the teeth" (in pain or anger), common Germanic (cognates: Old Norse grenja "to howl," grina "to grin;" Dutch grienen "to whine;" German greinen "to cry"), from PIE root *ghrei- "be open." Sense of "bare the teeth in a broad smile" is late 15c., perhaps via the notion of "forced or unnatural smile." Related: Grinned; grinning.

"emit rays of light," c. 1400, from beam (n.) in the "ray of light" sense. The sense of "shine radiantly" is from 1630s; that of "smile radiantly" is from 1804; that of "to direct radio transmissions" is from 1927. Related: Beamed; beaming.

"stop (what one is doing), run off," 1812, thieves' slang, of uncertain origin. The meaning "to smile" is from 1930 (see cheese (n.1)). For the sense of "annoy," see cheesed.

CHEESE IT. Be silent, be quiet, don't do it. Cheese it, the coves are fly; be silent, the people understand our discourse. ["Dictionary of Buckish Slang, University Wit, and Pickpocket Eloquence," London, 1811]

1550s, "to snort" (intransitive, of horses), perhaps from North Frisian sneere "to scorn," related to Old English fnæran "snort, gnash one's teeth," and of imitative origin (compare Danish snærre "grin like a dog," Middle Dutch, Middle High German snarren "to rattle").

The meaning "grin or smile contemptuously" is from 1670s; that of "speak derisively, insinuate contempt in words" is by 1707; the sense of "to curl the upper lip in scorn" is attested from 1775. Related: Sneered; sneering. Sneer word is in William Safire's columns from 1980 (he lists so-called, self-proclaimed, would-be, and purported).

"curd of milk coagulated, separated from the whey, pressed, and used as food," Old English cyse (West Saxon), cese (Anglian) "cheese," from West Germanic *kasjus (source also of Old Saxon kasi, Old High German chasi, German Käse, Middle Dutch case, Dutch kaas), from Latin caseus "cheese" (source of Italian cacio, Spanish queso, Irish caise, Welsh caws).

This is of unknown origin; perhaps (Watkins) from a PIE root *kwat- "to ferment, become sour" (source also of Prakrit chasi "buttermilk;" Old Church Slavonic kvasu "leaven; fermented drink," kyselu "sour," -kyseti "to turn sour;" Czech kysati "to turn sour, rot;" Sanskrit kvathati "boils, seethes;" Gothic hwaþjan "foam").

But de Vaan writes, "no etymology can be found which does not require some poorly-founded assumptions," and suggests a loan-word. Also compare fromage. Old Norse ostr, Danish ost, Swedish ost are related to Latin ius "broth, sauce, juice."

The earliest references would be to compressed curds of milk used as food; pressed or molded cheeses with rinds are from 14c. Transferred to other cheese-like substances by 1530s. As a photographer's word to make subjects hold a smile, it is attested from 1930, but in a reminiscence of schoolboy days, which suggests an earlier use. Probably for the forced smile involved in making the -ee- sound.

Green cheese is that newly made; the notion that the moon is made of green cheese as a type of a ridiculous assertion is from 1520s. To make cheeses (1835) was a schoolgirls' amusement of wheeling rapidly so one's petticoats blew out in a circle then dropping down so they came to rest inflated and resembling a wheel of cheese; hence, used figuratively for "a deep curtsy." Bartlett ("Dictionary of Americanisms," 1848) defines head cheese as "The ears and feet of swine cut up fine, and, after being boiled, pressed into the form of a cheese."

Middle English smith, from Old English smið "blacksmith, armorer, one who works in metal" (jewelers as well as blacksmiths), more broadly, "handicraftsman, practitioner of skilled manual arts" (also including carpenters), from Proto-Germanic *smithaz "skilled worker" (source also of Old Saxon smith, Old Norse smiðr, Danish smed, Old Frisian smith, Old High German smid, German Schmied, Gothic -smiþa, in aiza-smiþa "coppersmith"), from a suffixed form of PIE root *smi- "to cut, work with a sharp instrument" (source also of Greek smilē "knife for cutting and carving, chisel").

Attested as a surname by c. 975. Also used in a Middle English psalter of God, when he created light. Other common surnames meaning "smith" include Ferraro (Italian), Haddad (Arabic), Kovács (Hungarian, a Slavic loan-word), Kowalski (Polish), Herrero (Spanish), Kuznets (Russian), MacGowan (Irish, "son of the blacksmith").

1570s, "to look at furtively," probably a variant of earlier glout "to gaze attentively, stare, scowl, look glum, pout" (mid-15c.), from a Scandinavian source such as Old Norse glotta "to grin, smile scornfully and show the teeth," Swedish dialectal glotta "to peep;" or from Middle High German glotzen "to stare, gape," from the Germanic group of *gl- words that also includes glower, from PIE root *ghel- (2) "to shine." Sense of "to look at with malicious satisfaction, ponder with pleasure something that satisfies an evil passion" first recorded 1748. Johnson didn't recognize the word, and OED writes that it was probably "taken up in the 16th c. from some dialect." Related: Gloated; gloating. As a noun, from 1640s with sense of "side-glance;" 1899 as "act of gloating."

Whosoever attempteth anything for the publike ... the same setteth himselfe upon a stage to be glouted upon by every evil eye. [translators' "note to the reader" in the 1611 King James Bible]

c. 1200, talken, probably a diminutive or frequentative form related to Middle English tale "story," and ultimately from the same source as tale (q.v.), with rare English formative -k (compare hark from hear, stalk from steal, smirk from smile) and replacing that word as a verb. East Frisian has talken "to talk, chatter, whisper." Related: Talked; talking.

To talk (something) up "discuss in order to promote" is from 1722. To talk shop is from 1854. To talk turkey is from 1824, supposedly from an elaborate joke about a swindled Indian.

Phrase talking head is by 1966 in the jargon of television production, "an in-tight closeup of a human head talking on television." In reference to a person who habitually appears on television in talking-head shots (usually a news anchor), by 1970. The phrase is used earlier, in reference to the well-known magic trick (such as Señor Wences's talking head-in-the-box "Pedro" on the "Ed Sullivan Show"), and to actual talking heads in mythology around the world (Orpheus, Bran).

Old English cracian "make a sharp noise, give forth a loud, abrupt sound," from Proto-Germanic *krakojan (source also of Middle Dutch craken, Dutch kraken, German krachen); the whole group is probably ultimately imitative. Related: Cracked; cracking.

From c. 1300 as "to burst, split open" (intransitive), also transitive, "to cause to break into chinks." From 1785 as "break or crush into small pieces." Of the voice, "change tone suddenly," as that of a youth passing into manhood, c. 1600. Meaning "to open and drink" (a bottle) is from 16c.

From early 14c. as "to utter, say, speak, talk freely," especially "speak loudly or boastingly" (late 14c.). To crack a smile is from 1835, American English; to crack a joke is by 1732, probably from the "speak, say" sense. To crack the whip in the figurative sense is from 1886. Get cracking "go to work, start doing what is to be done" is by 1937.

What is a crack in English? A chat! The synonym is as perfect as possible; yet the words are subtly distinguished by a whole hemisphere of feeling. A chat, by comparison "wi' a crack," is a poor, frivolous, shallow, altogether heartless business. A crack is, indeed, only adequately to be defined as a chat with a good, kindly, human heart in it .... [P.P. Alexander, notes to "Last Leaves," Edinburgh, 1869]
