Word Origin & History

knock
O.E. cnocian (W.Saxon cnucian), likely of imitative origin. Meaning "deprecate, put down" is from 1892. Knockoff "cheap imitation" is from 1966. Knock out "to stun by a blow for a 10-count" in boxing is short for to knock out of time; slang knockout "attractive person" is from 1892. To knock oneself
out "make a great effort" is from 1936. Knock-kneed first attested 1774. Command knock it off "stop it" is first recorded 1902. Knocker "door banger" is from 1598; knockers "a woman's breasts" is from 1941. Knock up is 1663 in sense of "arouse by knocking at the door;" however it is little used in this sense in Amer.Eng., where the phrase means "get a woman pregnant" (1813), possibly ult. from knock "to copulate with" (1598; cf. slang knocking-shop "brothel," 1860).
"Knocked up in the United States, amongst females, the phrase is equivalent to being enciente, so that Englishmen often unconsciously commit themselves when amongst our Yankee cousins." [John Camden Hotten, "The Slang Dictionary," London, 1860]

Knock definition


"Though Orientals are very jealous of their privacy, they never knock when about to enter your room, but walk in without warning or ceremony. It is nearly impossible to teach an Arab servant to knock at your door. They give warning at the outer gate either by calling or knocking. To stand and call is a very common and respectful mode. Thus Moses commanded the holder of a pledge to stand without and call to the owner to come forth (Deut. 24:10). This was to avoid the violent intrusion of cruel creditors. Peter stood knocking at the outer door (Acts 12:13, 16), and the three men sent to Joppa by Cornelius made inquiry and 'stood before the gate' (10:17, 18). The idea is that the guard over your privacy is to be placed at the entrance." Knocking is used as a sign of importunity (Matt. 7:7, 8; Luke 13:25), and of the coming of Christ (Luke 12:36; Rev. 3:20).
