CATAWAMPUS [aka CATTYWAMPUS]
1. askew; awry.
2. positioned diagonally; cater-cornered.
3. diagonally; obliquely.
Etymology: of uncertain origin, entered English around the mid-1800s. Its first element, cata- is likely to be derived from the adverb cater meaning “diagonally.” The second element may be related to the Scottish term wampish meaning “to wave about or flop to and fro” .
