Section A.12 Structural Ambiguity

This section presents paired diagrams showing how the same sentence can have two different structural analyses, leading to two different meanings. Each pair shares the same words but differs in how phrases attach.
Syntax tree showing PP "with binoculars" attached to NP, meaning the man possesses binoculars
Figure A.12.1. PP Attaches to NP: I saw the man with binoculars (the man has binoculars)
Syntax tree showing PP "with binoculars" attached to VP, meaning the speaker used binoculars
Figure A.12.2. PP Attaches to VP: I saw the man with binoculars (I used binoculars)
Syntax tree showing "old" modifying only "men" in the coordinated NP
Figure A.12.3. Adjective Scope — Reading 1: old men and women (only men are old)
Syntax tree showing "old" modifying both "men and women" in the coordinated NP
Figure A.12.4. Adjective Scope — Reading 2: old men and women (both are old)

Figure A.12.5. Adjunct PP Modifies VP: She talked about the problem on the phone (she used the phone to talk)
Syntax tree showing "on the phone" modifying NP "the problem", meaning the problem exists on the phone
Figure A.12.6. PP Modifies NP: She talked about the problem on the phone (the problem is on the phone)
