英文词源

knock: knock: [OE] knock is a classic onomatopoeic word: that is to say, it originated in a direct imitation of the sound it denotes. The similar Swedish knacka ‘knock’ may be related. The figurative use of the word for ‘criticize’ originated in late 19th-century America.
knock (v.): Old English cnocian (West Saxon cnucian), "to pound, beat; knock (on a door)," likely of imitative origin. Meaning "deprecate, put down" is from 1892. Related: Knocked; knocking. Knock-kneed first attested 1774. Knock-down, drag-out is from 1827. Command knock it off "stop it" is first recorded 1880, perhaps from auctioneer's term for "dispose of quickly:"
At the commencement of the sales, he gave every one that wanted to purchase a paper containing a description of the lands that were to be sold; and, as the sales were cried, he called over the numbers and described the land; and when it got up to one dollar and a quarter an acre, if no body bid, after it was cried two or three times, he would say, knock it off, knock it off. [U.S. Senate record, 1834]
knock (n.): mid-14c., from knock (v.). As an engine noise, from 1899.
