oddball

The word 'oddball' is a distinctly American English compound, emerging in the mid-20th century. Its first element, 'odd', traces back to Old Norse 'oddr', which originally meant a point or triangle, a shape standing apart from others, a semantic seed that grew into meanings of singularity and peculiarity. The second element, 'ball', leverages the colloquial use of the word to categorize a person, akin to a 'character' or 'type', found in earlier slang like 'charley horse' or 'deadbeat'. The compound's logic is transparent: an 'odd ball' is a person who does not fit the standard mold, metaphorically a ball of a different, peculiar kind, highlighting deviation from the norm in behavior or character.

Structure: odd + ball - odd (Old Norse): From Old Norse 'oddr', meaning point, angle, or triangle, later developing the sense of being singular, left over, or unusual. In this compound, it provides the core meaning of "strange" or "unusual". - ball (Old English): From Old English 'beall', meaning a rounded object. In this compound, it functions as a slang suffix, likely influenced by terms like "hardball" or "screwball", to denote a person or type of character.
