Is to be a special verb? As in, does it have a special sort of name? Because I feel it doesn't create direct objects like most verbs do. For instance, in a simple sentence: "I throw the ball." "I" is the subject, "throw" is the verb, and "the ball" receives the action, therefore it is the direct object. But using that same logic: "This is him." To most people this is grammatically correct, because it follows the same structure. "Is" is the verb, "him" receives the action, therefore you use a direct object pronoun. But actually, grammatically correct it should be "This is he." Is it because there is some reflexivity in using "to be?"
