Answer:
ambiguity
Explanation:
Homonyms refer to words that have the same spelling but different meanings, while polysemous has to do with the different possible meanings of a word. As a result, both may produce uncertainty or inexactness of meaning when dealing with multi-meaning words. For instance, the words bat, band, book, summit paper, watch and can possess different meanings, which can create vagueness if the context does not provide clues to understand the meaning.
