What is "catawampus"

also catawampous, cattywampus, catiwampus, etc. (see "Dictionary of American Slang" for more), American colloquial. First element perhaps from obsolete cater "to set or move diagonally" (see catty-cornered); second element perhaps related to Scottish wampish "to wriggle, twist, or swerve about." Or perhaps simply the sort of jocular pseudo-classical formation popular in the slang of those times, with the first element suggesting Greek kata-.\n

\nEarliest use seems to be in adverbial form, catawampusly (1834), expressing no certain meaning but adding intensity to the action: "utterly, completely; with avidity, fiercely, eagerly." It appears as a noun from 1843, as a name for an imaginary hobgoblin or fright, perhaps from influence of catamount. The adjective is attested from the 1840s as an intensive, but this is only in British lampoons of American speech and might not be authentic. It was used in the U.S. by 1864 in a sense of "askew, awry, wrong" and by 1873 (noted as a peculiarity of North Carolina speech) as "in a diagonal position, on a bias, crooked."

a. 1 Out of alignment, crooked, cater-corner. 2 fierce, destructive. n. (context US English) A fierce imaginary animal, a bogeyman.
