bloviate (v.)youdaoicibaDictYouDict[bloviate 词源字典]
1857, American English, a Midwestern word for "to talk aimlessly and boastingly; to indulge in 'high falutin'," according to Farmer (1890), who seems to have been the only British lexicographer to notice it. He says it was based on blow (v.) on the model of deviate, etc.

It seems to have been felt as outdated slang already by late 19c. ("It was a leasure for him to hear the Doctor talk, or, as it was inelegantly expressed in the phrase of the period, 'bloviate' ...." ["Overland Monthly," San Francisco, 1872, describing a scene from 1860]), but it enjoyed a revival early 1920s during the presidency of Warren G. Harding, who wrote a notoriously ornate and incomprehensible prose (e.e. cummings eulogized him as "The only man, woman or child who wrote a simple declarative sentence with seven grammatical errors") at which time the word took on its connection with political speech; it faded again thereafter, but, with its derivative, bloviation, it enjoyed a revival in the 2000 U.S. election season that continued through the era of blogging.[bloviate etymology, bloviate origin, 英语词源]
daintily (adv.)youdaoicibaDictYouDict
c. 1300, "sumptuously;" late 14c., "elegantly," from dainty (adj.) + -ly (2).
elegant (adj.)youdaoicibaDictYouDict
late 15c., "tastefully ornate," from Middle French élégant (15c.), from Latin elegantem (nominative elegans) "choice, fine, tasteful," collateral form of present participle of eligere "select with care, choose." Meaning "characterized by refined grace" is from 1520s. Latin elegans originally was a term of reproach, "dainty, fastidious;" the notion of "tastefully refined" emerged in classical Latin. Related: Elegantly.
Elegant implies that anything of an artificial character to which it is applied is the result of training and cultivation through the study of models or ideals of grace; graceful implies less of consciousness, and suggests often a natural gift. A rustic, uneducated girl may be naturally graceful, but not elegant.
gingerly (adv.)youdaoicibaDictYouDict
"extremely cautiously" (of movements, etc.), c. 1600, earlier "elegantly, daintily" (1510s), of unknown origin. Perhaps [OED] from Old French gensor, comparative of gent "dainty, delicate," from Latin gentius "(well)-born" (see gentle). Meaning "extremely cautiously" is from c. 1600.
inelegant (adj.)youdaoicibaDictYouDict
c. 1500, from French inélégant (15c.), from Latin inelegantem (nominative inelegans) "not choice, without taste, without judgment," from in- "not" (see in- (1)) + elegans (see elegant). Related: Inelegantly; inelegance.
pimp (n.)youdaoicibaDictYouDict
c. 1600, of unknown origin, perhaps from Middle French pimpant "alluring in dress, seductive," present participle of pimper "to dress elegantly" (16c.), from Old French pimpelorer, pipelorer "decorate, color, beautify." Weekley suggests Middle French pimpreneau, defined in Cotgrave [French-English Dictionary, 1611] as "a knave, rascall, varlet, scoundrell," but Liberman is against this.
Judging by such recorded meanings of pimp as 'helper in mines; servant in logging camps,' this word was originally applied to boys and servants. [Liberman]
The word also means "informer, stool pigeon" in Australia and New Zealand and in South Africa, where by early 1960s it existed in Swahili form impimpsi. Pimpmobile first recorded 1973 (six years before Popemobile).
PIMP. A male procurer, or cock bawd; also a small faggot used about London for lighting fires, named from introducing the fire to the coals. [Grose, "Dictionary of the Vulgar Tongue," London, 1785]
