er, they cannot be delinked from each other. That is because lexical ambiguity may be a part of semantic ambiguity, though, in Levine's view, semantic ambiguity can exist even if lexical ambiguity does not (seem to) present itself. In that regard, however, Asher and Lascarides suggest that lexical ambiguity is ubiquitous. They link these two domains of ambiguity by making the point that "discourse structure affects the meanings of words, and [] meanings of words affect discourse structure" (69). Information flows back and forth "between the semantics of words and the structure of discourse" (Asher and Lascarides 69).
