Odor
Odor is not a denotation in itself; rather, it is a noun that refers to a specific scent or smell. Denotation refers to the literal meaning of a word, while odor specifically describes the characteristic of that smell, which can be pleasant, unpleasant, or neutral. Therefore, odor is an example of a concept that can have multiple denotations depending on context, but it is not a denotation itself.
