A simple subject is probably the most basic unit in sentence construction. A subject is a noun, which is a us of the sentence. This means that only one noun does the action, or connects, to the verb of the senteperson, place, thing, or idea. A subject tells us who or what the sentence is going to be about. Without a subject, we cannot have a complete sentence. A simple subject is a subject that has just one noun as the focnce. In order to understand simple subjects, we need to gain a better understanding of nouns. Here are some examples: People: firemen, boys, girls, teachers, parents Places: the beach, home, school, the grocery store Things: pencils, backpacks, tacos, cars Ideas: courage, imagination, fear, humor
