grog [grog 词源字典]: grog: [18] Grog comes from the nickname of Edward Vernon (1684–1757), the British admiral who in 1740 introduced the practice of serving rum and water (grog) to sailors in the Royal Navy rather than the hitherto customary neat rum (it was discontinued in 1970). His nickname was ‘Old Grogram’, said to be an allusion to the grogram cloak he always wore (grogram ‘coarse fabric’ [16] comes from French gros grain, literally ‘coarse grain’). Groggy [18], originally ‘drunk’, is a derivative.
[grog etymology, grog origin, 英语词源]
dollar (n.): 1550s, from Low German daler, from German taler (1530s, later thaler), abbreviation of Joachimstaler, literally "(gulden) of Joachimstal," coin minted 1519 from silver from mine opened 1516 near Joachimstal, town in Erzgebirge Mountains in northwest Bohemia. German Tal is cognate with English dale.

The thaler was a large silver coin of varying value in the German states (and a unit of the German monetary union of 1857-73 equal to three marks); it also served as a currency unit in Denmark and Sweden. English colonists in America used the word in reference to Spanish pieces of eight. Due to extensive trade with the Spanish Indies and the proximity of Spanish colonies along the Gulf Coast, the Spanish dollar was probably the coin most familiar in the American colonies and the closest thing to a standard in all of them; it was used in the government's records of public debt and expenditures; it had the added advantage of not being British. The Continental Congress in 1786 adopted dollar as a unit when it set up the modern U.S. currency system, which was based on the suggestion of Gouverneur Morris (1782) as modified by Thomas Jefferson. None were circulated until 1794 .
When William M. Evarts was Secretary of State he accompanied Lord Coleridge on an excursion to Mount Vernon. Coleridge remarked that he had heard it said that Washington, standing on the lawn, could throw a dollar clear across the Potomac. Mr. Evarts explained that a dollar would go further in those days than now. [Walsh]
Phrase dollars to doughnuts attested from 1890; dollar diplomacy is from 1910. The dollar sign ($) is said to derive from the image of the Pillars of Hercules, stamped with a scroll, on the Spanish piece of eight. However, according to the Bureau of Engraving and Printing of the U.S. Department of the Treasury:
[T]he most widely accepted explanation is that the symbol is the result of evolution, independently in different places, of the Mexican or Spanish "P's" for pesos, or piastres, or pieces of eight. The theory, derived from a study of old manuscripts, is that the "S" gradually came to be written over the "P," developing a close equivalent of the "$" mark. It was widely used before the adoption of the United States dollar in 1785.
gentleman (n.): c. 1200, perhaps mid-12c., "well-born man, man of good family or birth," also extended to Roman patricians and ancient Greek aristocrats, from gentle + man (n.); the compound probably is modeled on Old French gentilhomme (the English gentleman itself was borrowed into French in 18c.).

Given specific uses in late Middle English (small gentleman, gentleman-of-arms, gentleman-usher, etc.), hence in England the word often meant any man above the social rank of a yeoman, including the nobility, but it was sometimes restricted to those who bear a coat of arms but not a title; in U.S., "man of property, not engaged in business or a profession" (1789). The English word from the beginning also had a special sense "nobleman whose behavior conforms to the ideals of chivalry and Christianity," and gentleman came to be used loosely for any man of good breeding, courtesy, kindness, honor, strict regard for the feelings of others, etc.
The Gentleman is always truthful and sincere; will not agree for the sake of complaisance or out of weakness ; will not pass over that of which he disapproves. He has a clear soul, and a fearless, straightforward tongue. On the other hand he is not blunt and rude. His truth is courteous; his courtesy, truthful; never a humbug, yet, where he truthfully can, he prefers to say pleasant things. [J.R. Vernon, "Contemporary Review," 1869]
Eventually, in polite use, it came to mean a man in general, regardless of social standing. Related: Gentlemen. Gentleman's agreement is first attested 1929. Gentleman farmer recorded from 1749, "A man of means who farms on a large scale, employs hands, and does little or none of the work himself" [Craigie, "Dictionary of American English"].
grog (n.): 1749, "alcoholic drink diluted with water," supposedly a reference to Old Grog, nickname of Edward Vernon (1684-1757), British admiral who wore a grogram (q.v.) cloak and who in August 1740 ordered his sailors' rum to be diluted. George Washington's older half-brother Lawrence served under Vernon in the Caribbean and renamed the family's Hunting Creek Plantation in Virginia for him in 1740, calling it Mount Vernon. Eventually the word came popularly to mean "strong drink" of any kind. Grog shop "tavern where alcohol is sold by the glass" is from 1790.
portobello: type of mushroom, by 1986, no agreed-upon theory accounts for the name, which seems to be a marketing coinage. London's Portobello Road (one suggested source of the mushroom name) originally was the lane to Porto Bello House, named for the Panamanian place captured by the British under Vernon in 1739.
