" The definition of the ambiguous grammar is that: If ONE string in the language can be generated by grammar in TWO WAYS then it is ambiguous. But I think that the grammar (to generate x*y) is not ambiguous because the string x*y can be generated only in ONE way. It is problem of language designers that they have kept ONE string with TWO MEANINGS.

Lexical ambiguity is contrasted with semantic ambiguity. The former represents a choice between a finite number of known and meaningful context-dependent interpretations. The latter represents a choice between any number of possible interpretations, none of which may have a standard agreed-upon meaning. This form of ambiguity is closely related to vagueness.
