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 <em>bat, band, book, summit paper, watch </em>and <em>can</em> possess different meanings, which can create vagueness if the context does not provide clues to understand the meaning.
