pileyoudaoicibaDictYouDict[pile 词源字典]
pile: English has three words pile. The commonest, ‘heap’ [15], originally meant ‘pillar’. It comes ultimately from Latin pīla ‘pillar’, source also of English pilaster, pillar, etc. This evolved in meaning to ‘pier or harbour wall made of stones’, and inspired a derived verb pīlāre ‘heap up’ (source of English compile [14]).

The sense ‘heap’ came to the fore in Old French pile, and passed into English. Pile ‘post driven into the ground’ [OE] was borrowed into Old English from Latin pīlum ‘javelin’. It was originally used for a ‘throwing spear’, ‘arrow’, or ‘spike’, and its present-day use did not emerge (via ‘pointed stake or post’) until the Middle English period. Pile ‘nap on cloth, carpets, etc’ [15] probably comes via Anglo-Norman pyle from Latin pilus ‘hair’ (which may be distantly related to English pillage and pluck, and lies behind English depilatory [17]).

tapestryyoudaoicibaDictYouDict
tapestry: [15] The ultimate source of tapestry is Greek tápēs ‘tapestry, woven carpet’. Its diminutive from tapētion was borrowed via late Latin tapētium into Old French as tapis ‘carpet’. From this was derived the verb tapisser ‘cover with a carpet’, and this in turn formed the basis of a noun tapisserie ‘carpets, woven material’. English took it over and altered it to tapestry.
toastyoudaoicibaDictYouDict
toast: [14] Toast comes via Old French toster ‘roast, grill’ from Vulgar Latin *tostāre, a derivative of the past participle of Latin torrēre ‘parch’ (source of English torrid). Its use as a noun, meaning ‘toasted bread’, dates from the 15th century. It was common to put sippets or croutons of spiced toast into drinks to improve their flavour, and it was the custom of gallants in the 17th century, when (as they frequently did) they drank the health of ladies, to say that the name of the lady in question enhanced the flavour of their drink better than any toast.

That is supposedly the origin of the use of the term toast for ‘drinking someone’s health’.

=> thirst, torrent, torrid
caul (n.)youdaoicibaDictYouDict
early 14c., "close-fitting cap worn by women," from French cale "cap," back-formation from calotte, from Italian callotta, from Latin calautica "type of female headdress with pendent lappets," a foreign word of unknown origin. Medical use, in reference to various membranes, dates to late 14c. Especially of the amnion enclosing the fetus before birth from 1540s. This, if the child is born draped in it, was supersititously supposed to protect against drowning (cauls were advertised for sale in British newspapers through World War I).
clang (v.)youdaoicibaDictYouDict
1570s, echoic (originally of trumpets and birds), akin to or from Latin clangere "resound, ring," and Greek klange "sharp sound," from PIE *klang-, nasalized form of root *kleg- "to cry, sound." Related: Clanged; clanging.
clangor (n.)youdaoicibaDictYouDict
1590s, from Latin clangor "sound of trumpets (Virgil), birds (Ovid), etc.," from clangere "to clang," echoic (compare clang).
congressman (n.)youdaoicibaDictYouDict
1780, in reference to members of U.S. Congress, and it first appears in a piece of abuse (written by a Loyalist):
Ye coxcomb Congressmen, declaimers keen,
Brisk puppets of the Philadelphia scene ...
Congresswoman attested from 1918 (Jeannette Rankin (1880-1973) was the first).
dog (n.)youdaoicibaDictYouDict
Old English docga, a late, rare word, used in at least one Middle English source in reference to a powerful breed of canine. The word forced out Old English hund (the general Germanic and Indo-European word; see canine) by 16c. and subsequently was picked up in many continental languages (French dogue (16c.), Danish dogge, German Dogge (16c.)), but the origin remains one of the great mysteries of English etymology.

Many expressions -- a dog's life (c. 1600), go to the dogs (1610s), etc. -- reflect earlier hard use of the animals as hunting accessories, not pampered pets. In ancient times, "the dog" was the worst throw in dice (attested in Greek, Latin, and Sanskrit, where the word for "the lucky player" was literally "the dog-killer"), which plausibly explains the Greek word for "danger," kindynas, which appears to be "play the dog."

Slang meaning "ugly woman" is from 1930s; that of "sexually aggressive man" is from 1950s. Adjectival phrase dog-eat-dog attested by 1850s. Dog tag is from 1918. To dog-ear a book is from 1650s; dog-eared in extended sense of "worn, unkempt" is from 1894.
Notwithstanding, as a dog hath a day, so may I perchance have time to declare it in deeds. [Princess Elizabeth, 1550]
Phrase put on the dog "get dressed up" (1934) may look back to the stiff stand-up shirt collars that in the 1890s were the height of male fashion (and were known as dog-collars at least from 1883), with reference to collars worn by dogs. The common Spanish word for "dog," perro, also is a mystery word of unknown origin, perhaps from Iberian. A group of Slavic "dog" words (Old Church Slavonic pisu, Polish pies, Serbo-Croatian pas) likewise are of unknown origin.
faineant (adj.)youdaoicibaDictYouDict
1855; earlier as a noun (1610s); from French fainéant (16c.) "do-nothing," from fait, third person singular of faire "to do" (from Latin facere "to make, do;" see factitious) + néant "nothing" (compare dolce far niente). According to OED this is a French folk-etymology alteration of Old French faignant (14c.), present participle of faindre "to feign" (see feign). Applied in French to the late Merovingian kings, puppets in the hands of the palace mayors. Related: Faineance "the habit of doing nothing."
fanfare (n.)youdaoicibaDictYouDict
c. 1600, "a flourish sounded on a trumpet or bugle," from French fanfare "a sounding of trumpets" (16c.), from fanfarer "blow a fanfare" (16c.), perhaps echoic, or perhaps borrowed (with Spanish fanfarron "braggart," and Italian fanfano "babbler") from Arabic farfar "chatterer," of imitative origin. French fanfaron also came into English 1670s with a sense "boastful."
flourish (n.)youdaoicibaDictYouDict
c. 1500, "a blossom," from flourish (v.). Meaning "an ostentatious waving of a weapon" is from 1550s; that of "excessive literary or rhetorical embellishment" is from c. 1600; in reference to decorative curves in penmanship, 1650s; as "a fanfare of trumpets," 1590s.
ingrain (v.)youdaoicibaDictYouDict
1766, see engrain. Figurative use, of qualities, habits, etc., attested from 1851 (in ingrained). Of dyed carpets, etc., 1766, from in grain.
pedant (n.)youdaoicibaDictYouDict
1580s, "schoolmaster," from Middle French pédant (1560s) or directly from Italian pedante, literally "teacher, schoolmaster," of uncertain origin, apparently an alteration of Late Latin paedagogantem (nominative paedagogans), present participle of paedagogare (see pedagogue). Meaning "person who trumpets minor points of learning" first recorded 1590s.
puppet (n.)youdaoicibaDictYouDict
"doll moved by strings or wires" (later applied to puppets in glove form), 1530s, later form of Middle English popet "doll" (c. 1300; see poppet), from Old French popette "little doll, puppet," diminutive of popee "doll, puppet" (13c., Modern French poupée), from Vulgar Latin *puppa, from Latin pupa "girl; doll" (see pupil (n.1)).

Metaphoric extension to "one whose actions are manipulated by another" first recorded 1540s (as poppet). Puppet show attested from 1650s, earlier puppet-play (1550s). Puppet government is attested from 1884 (in reference to Egypt).
rain (v.)youdaoicibaDictYouDict
Old English regnian, usually contracted to rinan; see rain (n.), and compare Old Norse rigna, Swedish regna, Danish regne, Old High German reganon, German regnen, Gothic rignjan. Related: Rained; raining. Transferred and figurative use of other things that fall as rain (blessings, tears, etc.) is recorded from c. 1200.

To rain on (someone's) parade is attested from 1941. Phrase to rain cats and dogs is attested from 1738 (variation rain dogs and polecats is from 1650s), of unknown origin, despite intense speculation. One of the less likely suggestions is pets sliding off sod roofs when the sod got too wet during a rainstorm. (Ever see a dog react to a rainstorm by climbing up on an exposed roof?) Probably rather an extension of cats and dogs as proverbial for "strife, enmity" (1570s).
rampart (n.)youdaoicibaDictYouDict
"earthen elevation around a place for fortification," sometimes also including parapets, 1580s, from Middle French rempart, rampart, from remparer "to fortify," from re- "again" (see re-) + emparer "fortify, take possession of," from Old Provençal amparer, from Vulgar Latin *anteparare "prepare," properly "to make preparations beforehand," from Latin ante- "before" (see ante) + parare "prepare" (see pare). With excrescent -t in French, perhaps by influence of boulevart (see boulevard).
sea monkey (n.)youdaoicibaDictYouDict
1909 as a heraldic animal, 1964 as a U.S. proprietary name for brine shrimp (Artemia salina), which had been used as food for aquarium fish till they began to be marketed as pets by U.S. inventor Harold von Braunhut (d.2003), who also invented "X-Ray Specs" and popularized pet hermit crabs. He began marketing them in comic book advertisements in 1960 as "Instant Life," and changed the name to Sea Monkeys in 1964, so called for their long tails.
shag (n.)youdaoicibaDictYouDict
1590s, "cloth having a velvet nap on one side," perhaps from Old English sceacga "rough matted hair or wool," from Proto-Germanic *skagjan (cognates: Old Norse skegg, Swedish skägg "beard"), perhaps related to Old High German scahho "promontory," Old Norse skagi "a cape, headland," with a connecting sense of "jutting out, projecting." But the word appears to be missing in Middle English. Of tobacco, "cut in fine shreds," it is recorded from 1789; of carpets, rugs, etc., from 1946.
shampoo (v.)youdaoicibaDictYouDict
1762, "to massage," from Anglo-Indian shampoo, from Hindi champo, imperative of champna "to press, knead the muscles," perhaps from Sanskrit capayati "pounds, kneads." Meaning "wash the hair" first recorded 1860; extended 1954 to carpets, upholstery, etc. Related: Shampooed; shampooing.
