A pronoun is a word that replaces or refers to a noun or another pronoun.
Let's learn about pronouns.
The noun that a pronoun replaces is called its antecedent, and a pronoun absolutely, positively must agree with its antecedent.
The pronoun is the substitute teacher of the grammar world. It shows up in place of someone else, it does its very best, and people end up lying to it and telling it that their real name is Bubbles McGee and that a dolphin ate their homework.
Okay, it would be kind of hard to lie to a poor little pronoun.
Pronouns are extremely useful: without them, we'd have to repeat nouns over and over (and over and over and over and… well, you get the idea), which would make our sentences bulky and repetitive.
