Which word does not belong in the following list: Stop cop mop chop prop shop or crop?

Why this works

The answer "or" stands out in this riddle because it is the only word in the list that is not a noun. All the other words—stop, cop, mop, chop, prop, shop, and crop—are tangible items or actions, while "or" is a conjunction. This clever play on parts of speech makes "or" the odd one out, highlighting how the riddle relies on categorization to create its twist!
