What is the subject of a sentence? The subject of a sentence is the person or thing that is “doing” the verb. To find the subject, look for the verb and ask “Who or what is doing?” Who or what is singing? Who or what is sleeping?) Subjects are always in the NOMINATIVE CASE.
What is the direct object of a sentence? The direct object receives the action of the verb. To find the direct object, look for the verb and ask “Who or what is being verbed?” (as in Who or what is being kicked? Who or what is being read?) Direct objects take the ACCUSATIVE CASE.
