When it comes to English grammar, a subject is not the topic. The subject is the thing performing an action. It’s a boss.
The subject is the boss.
Subject = Boss
For example, in
Kwame learns,
Kwame does something. What does Kwame do? Kwame learns.
At the most basic level, subjects are usually nouns or pronouns. Other items can function as subjects, but we’ll get into that another time.
Let’s use Kwame, again.
“Kwame” is a proper noun, and “Kwame” is doing something. Ergo, “Kwame” is a subject.
Let’s use a pronoun, now.
He learns.
See. “He” is a pronoun, and “He” is doing something. Ergo, “He” is a subject.
Plural items can be subjects.
For example:
Ronnie, Bobby, Ricky, Mike, Ralph, and Johnny learn and grow.
Who does something? Ronnie, Bobby, Ricky, Mike, Ralph, and Johnny do something.
What do they do? They learn and grow.
These are the things that change boys to men. (Look it up.)
Be sure to avoid confusing subjects with objects. Subjects perform actions, and objects receive actions.
For example:
Kwame learns trigonometry.
“Trigonometry” is receiving action, so trigonometry is an object.
Be sure to avoid thinking that every pronoun or noun that you see in a sentence is a subject. Only nouns or pronouns that perform actions can be subjects.
