Pronouns

I can tell you the basics of a noun, pronoun, verb and adjective off the top of my head, but all of the things after that take me a minute to sort it all out and tell you what it is and how to use it. Pronouns have always taken me longer to think about.

According to Purdue's Online Writing Lab,
"

AGREE in NUMBER and PERSON and refer clearly to a specific noun.

Instead of saying "Karl Malone says, buy this car."
it should be
"I say, buy this car."
Josh thinks pronouns are great.
