When applying to Brown, you’ll be doing a fair bit of writing; there are essays on the CommonApp, essays on the Brown supplement, and essays that haunt you in your dreams. Perhaps your English teacher has red-penned your papers more than a few times for some of the following grammatical errors; they are mistakes that are quite common for high school students and adults alike. Your word processor’s Spell Check/Grammar Check function may not always catch these, and ultimately, having a few mild typos isn’t a disaster; still, remember to proofread, proofread, proofread, and then have someone else proofread!

And please, use the thesaurus sparingly. Words that have been ‘thesaurused-in’ can stick out like sore thumbs in an essay. Write in your voice with your words, so that your writing is an extension of your thoughts. All this being said, have fun writing your essay; it’s your chance to talk about what makes you you!
Some of the most frequent grammar/spelling stumbles, and some clarifying sentences with the correct usages of the words in question:
They’re/Their/There: ‘Their’ is a possessive pronoun, indicating that something belongs to ‘them.’ ‘There’ refers to a place. ‘They’re’ is a contraction of ‘they are.’
- e.g. They’re going to their Batcave, and they’re going to repair the Batmobile there.
We’re/Where/Were: Similarly to they’re/their/there, ‘we’re’ is a contraction of ‘we are,’ ‘where’ refers to a place, and ‘were’ is the past tense of the verb ‘to be.’
- e.g. We wanted to go to the Fortress of Solitude, but now we’re not sure where we want to go.
Your/You’re: ‘Your’ is a possessive pronoun, indicating that something belongs to ‘you.’ You’re is a contraction of ‘you are.’ If in doubt, replace the your/you’re in question with ‘you are’ and see if the sentence makes sense.
- e.g. You’re in charge of your own elephant!
Affect/Effect: ‘Affect’ is usually used as a verb (though it is also a noun), and ‘effect’ is generally used as a noun (though it is also a verb). When in doubt, consult the dictionary to determine the proper usage.
- e.g. The awe-inspiring effects of my transformation from Peter Parker into Spiderman were beginning to negatively affect my life.
Than/Then: ‘Than’ is a word that is used to compare things. ’Then’ refers to time.
- e.g. This llama is shaggier than that llama, so I will wait a few weeks, and then I’ll cut that llama’s hair.
It’s/Its: This one confuses many people. ‘It’s’ is a contraction of ‘it is,’ while ‘its’ is a possessive pronoun indicating that something belongs to ‘it.’
- e.g. As for the squirrel, it’s too bad that its tail was too big to fit in the costume.
Too/Two/To: ‘Too’ means ‘also.’ ‘Two’ is the number that comes after one. ‘To’ is a preposition.
- e.g. Two flying saucers are going to Mars, and I hear that a rocket ship may fly there, too.
Phase/Faze: These often get mixed up when people are writing about remaining cool as a cucumber in a tough situation, as in “That exam didn’t faze me.” ‘Phase’ is a noun and verb; it can refer to phases of matter (liquid, solid, gas), or stages in a life cycle, or part of a schedule.
- e.g. I wasn’t fazed by the kryptonite changing phases right before my eyes!
Peak/Pique: This is another popular mixup, especially when people want to talk about how something inspired curiosity in them.
- e.g. That lesson piqued my interest in mountain peaks.
Flare/Flair: These two are confused when people want to write about a talent/something special that they have.
- e.g. I have a flair for the dramatic; I like to wear neon orange pants that have a giant flare at the hem.
Alot: This is not a word. The correct way to write this is ‘a lot.’
Ending sentences with a preposition: Don’t do it. This is something up with which we shall not put. May the force be with you.
But/Butt: This should require no explanation…
Happy writing!
