muskyoudaoicibaDictYouDict[musk 词源字典]
musk: [14] Like the substance musk itself, the name musk came to Europe from the East. Its ultimate ancestor appears to have been Sanskrit muska ‘scrotum, testicle’. This meant literally ‘little mouse’ (it was a diminutive form of Sanskrit mūs ‘mouse’), and its metaphorical reapplication was due to a supposed similarity in shape between mice and testicles (a parallel inspiration gave rise to English muscle and mussel).

The gland from which the male musk deer secretes musk was held to resemble a scrotum, and so Persian took the Sanskrit word for ‘scrotum’ over, as mushk, and used it for ‘musk’. It reached English via late Latin muscus. The -meg of English nutmeg comes ultimately from Latin muscus, and other English relatives include muscat [16], the name of a grape that supposedly smells of musk, and its derivative muscatel [14].

redolentyoudaoicibaDictYouDict
redolent: [14] Etymologically, something that is redolent of something ‘smells’ of it. The word comes ultimately from Latin olēre ‘smell’, which was derived from the same base as produced English odour. Combination with the prefix re- ‘back’ resulted in redolēre ‘emit a smell’, from whose present participle English gets redolent. The Latin word was mainly used to convey the notion ‘smelling of something’, and this lies behind the English word’s metaphorical use for ‘suggestive, reminiscent, evocative’, first recorded in the early 19th century.

Pork barrel in the literal sense is from 1801, American English; meaning "state's financial resources (available for distribution)" is attested from 1907 (in full, national pork barrel); it was noted as an expression of U.S. President President William Howard Taft:
"Now there is a proposition that we issue $500,000,000 or $1,000,000,000 of bonds for a waterway, and then that we just apportion part to the Mississippi and part to the Atlantic, a part to the Missouri and a part to the Ohio. I am opposed to it. I am opposed to it because it not only smells of the pork barrel, but it will be the pork barrel itself. Let every project stand on its bottom." ["The Outlook," Nov. 6, 1909, quoting Taft]
The magazine article that includes the quote opens with:
We doubt whether any one knows how or when, or from what application of what story, the phrase "the National pork barrel" has come into use. If not a very elegant simile, it is at least an expressive one, and suggests a graphic picture of Congressmen eager for local advantage going, one after another, to the National pork barrel to take away their slices for home consumption.
Pork in this sense is attested from 1862 (compare figurative use of bacon). Pork chop is attested from 1858. Pork pie is from 1732; pork-pie hat (1855) originally described a woman's style popular c. 1855-65, so called for its shape.
