【正确答案】Lexical ambiguity is the kind of ambiguity that can be explained by reference to lexical meanings. This is usually cause by polysemy of homonymy. For example, in the sentence I saw a bat, a bat might refers to an animal, or, among others, a table tennis bat.
Structural ambiguity, also know as syntactic ambiguity, can be caused because the surface structure of a sentence or phrase is ambiguous. For example: my small child's cot. This phrase can be understood in three ways for having three surface structures.
