Nouns as Subjects and Objects
A noun is 1 of the 8 parts of speech. A noun is a word for a person, place, or thing.
A thing can be living, such as an animal or plant.
A thing can be nonliving, such as a desk or pencil.
A thing can be concrete (something physical), such as chocolate.
A thing can be abstract (an idea that we can think about but not physically see, touch, hear, or smell), such as happiness, health, and peace.
Nouns have different uses, or functions.
A noun or pronoun can be used as the subject in a sentence. A subject is the person, place, or thing that performs the action (verb).
A noun or pronoun can be used as the object in a sentence. An object is the person, place, or thing that receives the action.
Let's look at a noun: student
In these sentences, the word "student" is being used as the subject of the sentence because the student is doing the action:
A few minutes ago, the student sat down in front of a computer. Now the student is reading some information. Tomorrow, the student is going to take a test. Will the student pass the test?
In these sentences, the word "student" is being used as the object of the sentence because someone else is doing the action. The student is "receiving" the effects of the action:
The tutor helped the student. The teacher asked the student a question. The secretary called the student.
