Is there any rule to know whether a word is an adjective or a past participle when it follows "to be"? For example:
John is hurt.
The website where I found this sentence says that “hurt” is a past participle in a passive sentence.
Are you hurt?
I found this sentence in my dictionary, which says that “hurt” is an adjective.
I feel confused. Is "hurt" an adjective or a past participle, and is it active or passive?
