cognizance [cognizance 词源字典]: cognizance: [14] Latin gnōscere meant ‘know’ (it is related to know and notion). From it was derived the compound verb cognōscere ‘get to know, recognize, acknowledge’. Its present participial stem cognōscent- formed the basis of a Vulgar Latin noun *connōscentia, which passed into Old French as connoissance. English borrowed this as conisance, restoring the Latin g to the spelling in the 15th century, which eventually affected the word’s pronunciation.

Also from the Latin present participle came Italian conoscente, which in its latinized form was borrowed into English as cognoscente in the 18th century. Meanwhile, the past participial stem of the Latin verb, cognit-, produced the noun cognitiō, source of English cognition [15]. The infinitive form of the Latin verb passed into Old French as connoître, from which was derived the agent noun connoisseur, borrowed into English in the 18th century (modern French has connaisseur).

philately: philately: [19] When a Monsieur Herpin, a French stamp-collector, was looking for an impressive and learned-sounding term for his hobby, he was hampered by the fact that the Greeks and Romans did not have postage stamps, and therefore there was no classical term for them. So he decided to go back a stage beyond stamps, to the days of franking with a post-mark. In France, such letters were stamped franc de port ‘carriage-free’, and the nearest he could get to this in Greek was atelés ‘free of charge’, a compound formed from a- ‘not’ and télos ‘payment’.

Using the Greek prefix phil- ‘loving, love of’ (as in philosophy and a wide range of other English words) he created philatélie, which made its first appearance in English in 1865.
brinkmanship (n.): also brinksmanship, with parasitic -s- and construction based on salesmanship, sportsmanship, etc.; from brink (the image of the brink of war dates to at least 1840).

Associated with the policies advocated by John Foster Dulles (1888-1959), U.S. Secretary of State 1953-1959. The word springs from Dulles' philosophy as outlined in a magazine interview [with Time-Life Washington bureau chief James Shepley] early 1956:
The ability to get to the verge without getting into the war is the necessary art. If you cannot master it, you inevitably get into war. If you try to run away from it, if you are scared to go to the brink, you are lost.
The quote was widely criticized by the Eisenhower Administration's opponents, and the first attested use of brinkmanship seems to have been in such a context, a few weeks after the magazine appeared, by Democratic presidential candidate Adlai Stevenson criticizing Dulles for "boasting of his brinkmanship, ... the art of bringing us to the edge of the nuclear abyss."
cognizance (n.): mid-14c., from Anglo-French conysance "recognition," later, "knowledge," from Old French conoissance "acquaintance, recognition; knowledge, wisdom" (Modern French connaissance), from past participle of conoistre "to know," from Latin cognoscere "to get to know, recognize," from com- "together" (see co-) + gnoscere "to know" (see notice (n.)). The -g- was restored in English spelling 15c. and has gradually affected the pronunciation, which was always "con-." The old pronunciation lingered longest in legal use.
fathom (v.): Old English fæðmian "to embrace, surround, envelop," from a Proto-Germanic verb derived from the source of fathom (n.); cognates: Old High German fademon, Old Norse faþma. The meaning "take soundings" is from c. 1600; its figurative sense of "get to the bottom of, penetrate with the mind, understand" is from 1620s. Related: Fathomed; fathoming.
gangway (n.): "temporary passageway" to a ship, building under construction, etc., ultimately from Old English gangweg "road, passage, thoroughfare;" a compound of gang (n.) in its original sense "a going, journey, way, passage" and way (n.). Nautical use dates from 1680s in reference to a passage on the ship, from 1780 of the opening at the side whereby people enter and leave, and by 1840s of the board or bridge they use to get to and from the dock. As a command to clear way, attested by 1912, American English. In British parliamentary use, with somewhat the same sense aisle has in the U.S. Congress.
Below the g[angway], as a parliamentary phrase, is applied to members whose customary seat does not imply close association with the official policy of the party on whose side of the House they sit. [Fowler]
get (v.): c. 1200, from Old Norse geta (past tense gatum, past participle getenn) "to obtain, reach; to be able to; to beget; to learn; to be pleased with," a word of very broad meaning, often used almost as an auxilliary verb, also frequently in phrases (such as geta rett "to guess right"). This is from Proto-Germanic *getan (cognates: Old Swedish gissa "to guess," literally "to try to get"), from PIE root *ghend-, also *ghed- "seize, take" (cognates: Greek khandanein "to hold, contain," Lithuanian godetis "be eager," second element in Latin prehendere "to grasp, seize," Welsh gannu "to hold, contain," Old Church Slavonic gadati "to guess, suppose").

Old English, as well as Dutch and Frisian, had the verb almost exclusively in compounds (such as begietan, "to beget;" forgietan "to forget"). Vestiges of an Old English cognate *gietan remain obliquely in modern past participle gotten and original past tense gat, also Biblical begat.

In compound phrases with have and had it is grammatically redundant, but often usefully indicates possession, obligation, or necessity, or gives emphasis. The word and phrases built on it take up 29 columns in the OED 2nd edition; Century Dictionary lists seven distinct senses for to get up.
"I GOT on Horseback within ten Minutes after I received your Letter. When I GOT to Canterbury I GOT a Chaise for Town. But I GOT wet through before I GOT to Canterbury, and I HAVE GOT such a Cold as I shall not be able to GET rid of in a Hurry. I GOT to the Treasury about Noon, but first of all I GOT shaved and drest. I soon GOT into the Secret of GETTING a Memorial before the Board, but I could not GET an Answer then, however I GOT Intelligence from the Messenger that I should most likely GET one the next Morning. As soon as I GOT back to my Inn, I GOT my Supper, and GOT to Bed, it was not long before I GOT to Sleep. When I GOT up in the Morning, I GOT my Breakfast, and then GOT myself drest, that I might GET out in Time to GET an Answer to my Memorial. As soon as I GOT it, I GOT into the Chaise, and GOT to Canterbury by three: and about Tea Time, I GOT Home. I HAVE GOT No thing particular for you, and so Adieu." [Philip Withers, "Aristarchus, or the Principles of Composition," London, 1789, illustrating the widespread use of the verb in Modern English]
