c. 1300 (late 12c. as a surname), "resident or inhabitant of Picardy," the region in northeastern France, from Old French pic (Modern French pique) "pike" (see pike (n.1)); the characteristic weapon of the people who lived in this part of northern France in ancient times.
a puzzle or riddle consisting of words or phrases represented by pictures of objects whose names resemble in sound the words or phrases intended, c. 1600, apparently from Latin rebus (and meaning literally "by means of objects"), ablative plural of res "thing, object" (see re). According to French sources (Gilles Ménage, "Les origines de la langue françoise," 1650), principally from the phrase de rebus quæ geruntur "of things which are going on," in reference to the satirical pieces composed by Picardy clerks at carnivals, subtle satires of current events using pictures to suggest words, phrases or things. Or this use of the Latin word might be from the representations being non verbis sed rebus "not by words, but by things."
"military reinforcement, one of a newly raised body of soldiers or sailors to supply a military deficiency," 1640s, from recruit (v.), replacing earlier recrew, recrue; or from obsolete French recrute, alteration of recreue "a supply," recrue "a levy of troops" (late 16c.). This is a Picardy or Hainault dialect variant of recrue "a levy, a recruit," literally "a new growth," from Old French recreu (12c.), past participle of recreistre "grow or increase again," from re- "again" (see re-) + creistre "to grow," from Latin crescere "to grow" (from PIE root *ker- (2) "to grow").
"The French word first appeared in literary use in gazettes published in Holland, and was disapproved of by French writers in the latter part of the 17th c." [OED]. The French word also is the source of Dutch recruut, German Recrut, Swedish rekryt. The general sense of "one who has newly filled a vacancy in any body or class of persons" also is from 1640s.
a complicated word of uncertain history. First attested late 15c. in the sense "lewd person" (of either sex; since c. 1700 applied exclusively to women); probably [Middle English Compendium] from Old French baud "gay, licentious" (from Frankish *bald "bold" or some such Germanic source; see bold), despite the doubts of OED. The 15c. English word perhaps is a shortening of baude-strote "procurer or procuress of prostitutes" (c. 1300).
For the French sense evolution from "bold" to "lewd," compare Old French baudise "ardor, joy, elation, act of boldness, presumption;" baudie "elation, high spirits," fole baudie "bawdry, shamelessness." The Old French word also is the source of French baudet "donkey," in Picardy dialect "loose woman."
The second element in baude-strote would be trot "one who runs errands," or Germanic *strutt (see strut (v.)). There was an Old French baudestrote, baudetrot of the same meaning (13c.), and this may be the direct source of Middle English baude-strote. The obsolete bronstrops "procuress," frequently found in Middleton's comedies, probably is an alteration of baude-strote.
digraph used in Old French for the "tsh" sound. In some French dialects, including that of Paris (but not that of Picardy), Latin ca- became French "tsha." This was introduced to English after the Norman Conquest, in words borrowed from Old French such as chaste, charity, chief (adj.). Under French influence, -ch- also was inserted into Anglo-Saxon words that had the same sound (such as bleach, chest, church) which in Old English still was written with a simple -c-, and into those that had formerly been spelled with a -c- and pronounced "k" such as chin and much.
It turns up as well in words from classical languages (chaos, echo, etc.). Most uses of -ch- in Roman Latin were in words from Greek, which in Greek would be pronounced correctly as /k/ + /h/, as in modern blockhead, but most Romans would have said merely /k/, and this was the regular pronunciation in English. Before c. 1500 such words were regularly spelled with a -c- (Crist, cronicle, scoole), but Modern English has preserved or restored the etymological spelling in most of them (chemical, chorus, monarch).
Sometimes ch- is written to keep -c- hard before a front vowel, as still in modern Italian. In some languages (Welsh, Spanish, Czech) ch- can be treated as a separate letter and words in it are alphabetized after -c- (or, in Czech and Slovak, after -h-). The sound also is heard in words from more distant languages (as in cheetah, chintz), and the digraph also is used to represent the sound in Scottish loch.
