kettle (n.)youdaoicibaDictYouDict[kettle 词源字典]
Old English cetil (Mercian), from Proto-Germanic *katilaz (compare Old Saxon ketel, Old Frisian zetel, Middle Dutch ketel, Old High German kezzil, German Kessel), probably from Latin catillus "deep pan or dish for cooking," diminutive of catinus "bowl, dish, pot." One of the few Latin loan-words in Proto-Germanic, along with *punda- "measure of weight or money" (see pound (n.1)) and a word relating to "merchant" that yielded cheap (adj.). "[I]t is striking that all have something to do with trade" [Don Ringe, "From Proto-Indo-European to Proto-Germanic," Oxford 2006]. Spelling with a -k- (c. 1300) probably is from influence of Old Norse cognate ketill. The smaller sense of "tea-kettle" is attested by 1769.[kettle etymology, kettle origin, 英语词源]
path (n.)youdaoicibaDictYouDict
Old English paþ, pæþ "path, track," from West Germanic *patha- (cognates: Old Frisian path, Middle Dutch pat, Dutch pad, Old High German pfad, German Pfad "path"), of uncertain origin. The original initial -p- in a Germanic word is an etymological puzzle. Don Ringe ("From Proto-Indo-European to Proto-Germanic," Oxford 2006) describes it as "An obvious loan from Iranian ..., clearly borrowed after Grimm’s Law had run its course." Watkins says the word is "probably borrowed (? via Scythian) from Iranian *path-," from PIE root *pent- "to tread, go, pass" (source of Avestan patha "way;" see find (v.)), but this is too much of a stretch for OED and others. In Scotland and Northern England, commonly a steep ascent of a hill or in a road.
polenta (n.)youdaoicibaDictYouDict
Old English polente, from Latin pollenta, polenta, literally "peeled barley," related to pollen "fine flour," from Proto-Indo-European *pel- (1) "flour; dust" (see pollen). Later reborrowed from Italian polenta, from the Latin word.
polish (v.)youdaoicibaDictYouDict
early 14c., polischen "make smooth," from Old French poliss-, present participle stem of polir (12c.) "to polish, decorate, see to one's appearance," from Latin polire "to polish, make smooth; decorate, embellish;" figuratively "refine, improve," said to be from Proto-Indo-European *pel- "to thrust, strike, drive" (via the notion of fulling cloth). The sense of "free from coarseness, to refine" first recorded in English mid-14c. Related: Polished; polishing. Slang polish off "finish" is 1837, from notion of applying a coat of polish being the final step in a piece of work.
Reich (n.)youdaoicibaDictYouDict
German, "kingdom, realm, state," from Old High German rihhi, related to Old English rice, from Proto-Germanic *rikja "rule" (cognates: Old Norse riki, Danish rige, Old Frisian and Middle Dutch rike, Dutch rijk, Gothic reiki), from PIE *reg- (1) "move in a straight line," hence, "direct in a straight line, rule, guide" (see regal). Don Ringe, "From Proto-Indo-European to Proto-Germanic" [Oxford 2006] identifies it as a Celtic loan-word in Germanic rather than a direct evolution from PIE, based on the vowel. Used in English from 1871-1945 to refer to "the German state, Germany." Most notoriously in Third Reich (see third); there never was a First or Second in English usage.
skive (v.1)youdaoicibaDictYouDict
"split or cut into strips, pare off, grind away," 1825, from a Scandinavian source such as Old Norse skifa "to cut, split," from Proto-Germanic *skif-, from Proto-Indo-European *skei- "to cut, split" (see shed (v.)). Related: Skived; skiving.
wheel (n.)youdaoicibaDictYouDict
Old English hweol, hweogol "wheel," from Proto-Germanic *hwewlaz- (cognates: Old Norse hvel, Old Swedish hiughl, Old Frisian hwel, Middle Dutch weel), from PIE *kw(e)-kwl-o- "wheel, circle," suffixed, reduplicated form of root *kwel- (1) (see cycle (n.)).
The root wegh-, "to convey, especially by wheeled vehicle," is found in virtually every branch of Indo-European, including now Anatolian. The root, as well as other widely represented roots such as aks- and nobh-, attests to the presence of the wheel -- and vehicles using it -- at the time Proto-Indo-European was spoken. [Watkins, p. 96]
Figurative sense is early 14c. Wheel of fortune attested from early 15c. Slang wheels "a car" is recorded from 1959. Wheeler-dealer is from 1954, a rhyming elaboration of dealer.

second letter of the Latin alphabet, corresponding to Greek beta, Phoenician beth, literally "house." It "has nothing of that variety of pronunciation shown by most English letters" [Century Dictionary]. The Germanic "b" is said to represent a "bh" sound in Proto-Indo-European, which continued as "bh" in Sanskrit, became "ph" in Greek (brother/Greek phrater; bear (v.)/Greek pherein) and "f" in Latin (frater, ferre).

Often indicating "second in order." B-movie is by 1939, usually said to be so called from being the second, or supporting, film in a double feature. Some film industry sources say it was so called for being the second of the two films major studios generally made in a year, and the one cast with less headline talent and released with less promotion. And early usage varies with grade-B movie, suggesting a perceived association with quality.

B-side of a gramophone single is by 1962 (flip-side is by 1949). B-girl, abbreviation of bar girl, U.S. slang for a woman paid to encourage customers at a bar to buy her drinks, is by 1936.
