Unfortunately, they are not all English constructions.
1-He can't see anybody he likes.
Absent context, that requires some clarification. Does it mean that person is not allowed (permitted) to see the people he likes or does it mean he is somehow unable to see the people he likes? Does it mean he is not permitted to talk to the people he wants to talk to? Or does it mean he is not allowed to talk to the people he wants to talk to?
2-He can't buy any book he wants.
That also is somewhat ambiguous. Does it mean he is unable to buy any book he wants to buy? Does it mean he is not allowed to buy any book he wants to buy? Is he permitted to buy books he doesn't want? :wink:
Aren't these sentences ambiguous:
1a-He can see nobody he likes.
1b-He can't see everybody he likes.
Does the first sentence mean that he is not allowed to see the people he likes or that he is unable to see the people he likes. Is he permitted to see people he doesn't like? :wink:
Does the second sentence mean that he can (is allowed to) see some of the people he likes but not all of the people he likes or that he cannot (is not allowed to) see any of the people he likes? Or does it mean that he can (is able to) see some of the people he likes but not all of the people he likes or that he cannot (is not able to) see any of the people he likes?
Yes, I think they are ambiguous. :wink:
1a-He can buy no book he likes.
1b-He can't buy every book he likes.
Can he buy books he doesn't like? Can he buy some of the books he likes? (Etc., etc.) :wink:
Absent context, those sentences are quite ambiguous.
