Ambiguous - word sense and structural. Since the lexical categories of the two senses differ, structural as well as word sense ambiguity is present. I'd call this a kind of scoping ambiguity, similar to what you'd get with Every person saw her duck . There is further ambiguity in the word saw which could be the past tense form of see , or the present tense of the verb meaning to use the cutting tool called a saw . A man stopped at every truck stop.

In the present tense, there is no further ambiguity.
