[QUOTE=Lucky;807628]He is home.
I always thought a linking verb must be followed by adjective or noun (below):
NOT A TEACHER
(1) May I suggest that "is" in "He is home" is not a linking verb.
(2) As you know, sometimes "to be" is a "real" verb that means something like to
exist. You remember Shakespeare's famous "To be or not to be." That is, to exist/live
(3) As the Editor said, the perfect sentence (according to the rules) is "He is at home." It answers the question: Where is he? (Which "proves" that the "is" in your sentence is not a linking verb.) Of course, many speakers delete (drop) the "at" in ordinary conversation and ordinary writing.
(4) In "He went home," the noun "home" is being used as an adverb to modify a verb
of motion. This is one of those exceptions that you find in any language.
