​Common Grammar Mistakes

​Your vs You're

Your and you’re are homophones.

Your is a possessive pronoun. It indicates that something belongs to a singular second person. Ex: You forgot YOUR homework.
You’re is a contraction of you are. Ex: You're late for class.

​Affect vs. Effect

Affect is a verb that means “to cause an effect.” Effect is a noun that refers to a result.

Example: How will the snow affect our commute time?
Example: Drinking coffee will have an effect on my concentration.

​That vs. Which

That is used to introduce a clause that adds necessary information to a sentence. Which is used to introduce a clause that adds detail but isn’t critical to the sentence.

Example: One of my students, the one that is always late, is struggling to keep up with class work.
Example: My car, which is black, needs winter tires
