​Common Grammar Mistakes

​Your vs You're

Your and you’re are homophones.
That means they sound the same when spoken aloud but have two different meanings.

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

​Less vs. Fewer

Less is used to describe an abstract or otherwise uncountable amount of items. Fewer is used for countable numbers of items.

Example: The students had less time to work on the assignment today.

Example: If fewer people used disposable water bottles, there would be less plastic in landfills.

The most common semicolon use is joining two independent clauses without using a coordinating conjunction like and.
Semicolons can also replace commas when listing items that already use commas, such as listing cities and states.

Semicolons

Examples:

I ordered a cheeseburger for lunch; I'll have a salad for supper.

Taylor has gone to the library; her brother has gone to watch the soccer game.

Semicolons

Semicolons are used instead of a conjunction word (and, but, or). You CANNOT use both a conjunction and a semicolon.

Instead: On vacation in Africa, I saw a lion; it was eating a zebra.
