Subject of a Sentence

The subject is the person or thing (object) that the sentence is about. This person or thing is doing something in the sentence.
 

1. A subject can be a person.

Here, the subject is Oliver.
 

2. A subject can also be an object .

Here, the subject is the boat.

Tip: To figure out who or what is the subject, first find the verb of the sentence. Then ask yourself who or what is doing that action.

Here, the verb is took.

Now ask yourself, who or what took the shower? In this case, it is a person referred to by the subject pronoun she. So, she is the subject.

Similarly,

Here, the verb is ate.

Now ask yourself who is doing the action or simply who ate all the cake? In this case, it is a person referred to by the subject pronoun he. So, he is the subject.
 

In every case, every sentence has a subject. But wait, there is an exception! In the case of an imperative sentence, there is usually no subject at all.

Do you know what an imperative sentence is? It's when someone gives a command or an order.

In the three sentences above, you don't see a subject. The subject is "you." It does not need to be said; it is understood.
 

Note: Sometimes, you can place "you" in the imperative. In this context, it often expresses an irritation.
