In English grammar, a subject is a noun, pronoun, or phrase that identifies the person or thing that is doing, experiencing, or being talked about in a sentence.
Basically, it’s the part of a sentence that is doing the verb. For example, in the sentence “The dog is playing,” “The dog” is the subject. It is the noun that is doing the verb (in this case, the verb is “is playing”).
Pronouns can also be subjects. For example, in the sentence “He is playing,” the pronoun “He” is the subject.
You can also have a phrase as the subject of a sentence. For example, in the sentence “The big, hairy dog is playing,” the phrase “The big, hairy dog” is the subject.
It’s important to note that the subject of a sentence doesn’t have to be the first thing you write or say. It can come after the verb (as in the sentence “Is the dog playing?”) or even in the middle of the sentence (as in the sentence “The dog that is black is playing”).
Now that you know what a subject is, let’s look at some ways you can use subjects in your writing.
One common way to use a subject is to start a sentence with it. For example, you might say, “The dog is playing.” In this sentence, “The dog” is the subject and “is playing” is the verb.
You can also use a subject to describe someone or something. For example, you might say, “The dog is big.” In this sentence, “The dog” is the subject and “is big” is the verb.
You can also use a subject to ask a question. For example, you might say, “Is the dog playing?” In this sentence, “Is” is the verb and “the dog” is the subject.
Finally, you can use a subject to give a command. For example, you might say “Sit, dog!” In this sentence, “Sit” is the verb and “dog” is the subject.
Now that you know what a subject is and some of the ways you can use it, you’re ready to start using subjects in your own writing. Remember, a subject is simply a noun, pronoun, or phrase that identifies the person or thing that is doing, experiencing, or being talked about in a sentence. With that in mind, you can use subjects to start sentences, describe people or things, ask questions, and give commands.
