1540s, "having a conscience;" 1580s, of actions, "consonant with right or duty;" 1640s, of persons, "governed by conscience."

advice (n.)

late 13c., auys "opinion," from Old French avis "opinion, view, judgment, idea" (13c.), from phrase ço m'est à vis "it seems to me," or from Vulgar Latin *mi est visum "in my view," ultimately from Latin visum, neuter past participle of videre "to see" (from PIE root *weid- "to see"). Meaning "opinion offered as worthy to be followed, counsel" is from late 14c.

The unetymological -d- (on model of Latin words in ad-) was inserted occasionally in French by scribes 14c.-16c. and was made regular in English 15c. by Caxton. Substitution of -c- for -s- is 18c., to preserve the breath sound and to distinguish from advise. Early Modern English tended to alternate -ce and -se endings in otherwise confusable noun-verb pairs, using -se for the verb and -ce for the noun: devise/device, peace/appease, practice/practise, license/licence, prophecy/prophesy.

polka (n.)

kind of lively round-dance which originated in Bohemia, 1844, from French polka, German Polka, probably from Czech polka, the dance, literally "Polish woman" (Polish Polka), fem. of Polak "a Pole" (see Pole). The word might also be an alteration of Czech pulka "half," for the half-steps of Bohemian peasant dances. Or it could be a merger of the two. The dance was in vogue first in Prague, 1835; it reached London by the spring of 1842.

Vous n'en êtes encore qu'au galop, vieil arriéré, et nous en sommes à la polka! Oui, c'est la polka que nous avons dansée à ce fameux bal Valentino. Vous demandez ce que c'est que la polka, homme de l année dernière! La contredanse a vécu; le galop, rococo; la valse à deux temps, dans le troisième dessous; il n'y a plus que la polka, la sublime, l'enivrante polka, dont les salons raffolent, que les femmes de la haute, les banquiéres les plus cossues et les comtesses les plus choenosophoses étudient jour et nuit. ["La France Dramatique," Paris, 1841]

As a verb by 1846 (polk also was tried).

twice (adv.)

"two times, on two occasions, in two instances," late Old English twies, from Old English twiga, twigea "two times," from Proto-Germanic *twiyes (source also of Old Frisian twia, Old Saxon tuuio), from PIE *dwis-, adverbial form of root *dwo- "two." Spelling with -ce reflects the voiceless pronunciation.

Life is as tedious as a twice-told tale
Vexing the dull ear of a drowsy man.
["King John," III.iv.]

Think twice, then speak was an "old Prouerbe" by 1623. At twice, though less common than at once, means "at two distinct times; by two distinct operations."

also goddamn, late 14c., "the characteristic national oath of Englishmen" [Century Dictionary]. from God + damn (v.). Goddam (Old French godon, 14c.) was said to have been a term of reproach applied to the English by the French.

Mais, fussent-ils [les anglais] cent mille Goddem de plus qu'a present, ils n'auront pas ce royaume. [Joan of Arc, 1431, quoted in Prosper de Barante's "Histoire des ducs de Bourgogne"]

Hence French godan "fraud, deception, humbug" (17c.). Compare Old French godeherre "characteristic exclamation uttered by the Germans," and goditoet, also considered a characteristic exclamation of the English. Goddammes was the nickname given by Puritans to Cavaliers, in consequence of the latter's supposed frequent employment of that oath.
