Word Origin and History for button up

button

n.

c.1300 (surname Botouner "button-maker" attested from mid-13c.), from Old French boton "a button," originally "a bud" (12c., Modern French bouton), from bouter, boter "to thrust," common Romanic (cf. Spanish boton, Italian bottone), ultimately from Germanic (see butt (v.)). Thus a button is, etymologically, something that pushes up, or thrusts out.

Meaning "point of the chin" is pugilistic slang, by 1921. A button as something you push to create an effect by closing an (electrical) circuit is attested from 1840s. Button-pusher as "deliberately annoying or provocative person" is attested by 1990 (in reference to Bill Gates, in "InfoWorld" magazine, Nov. 19). In the 1980s it meant "photographer."

lip

n.

Old English lippa, from Proto-Germanic *lepjon (cf. Old Frisian lippa, Middle Dutch lippe, Dutch lip, Old High German lefs, German Lefze, Swedish läpp, Danish læbe), from PIE *leb- "to lick; lip" (cf. Latin labium).

French lippe is from a Germanic source. Transferred sense of "edge or margin of a cup, etc." is from 1590s. Slang sense "saucy talk" is from 1821, probably from move the lip (1570s) "utter even the slightest word (against someone)." To bite (one's) lip "show vexation" is from early 14c. Stiff upper lip as a sign of courage is from 1833. Lip gloss is attested from 1939; lip balm from 1877. Related: Lips.
