| Published date

Last Updated

If you’re prepping for the HESI A2 entrance exam, the grammar section is one part that can trip you up, especially when it comes to commonly confused words. These are those sneaky words that look or sound similar but have totally different meanings. Screw these up, and you’re in for a world of hurt on exam day. In this guide, we’ll cover the most commonly confused words you might encounter in the HESI A2 grammar section and give you some tips to ace them.

What Are Commonly Confused Words in the HESI A2 Grammar Section?

Commonly confused words are those that can easily be mixed up due to similar spellings, pronunciations, or meanings. The HESI A2 grammar section will test your ability to differentiate between these words and use them correctly in context. Here’s what you’re dealing with:

  • Number of Questions: The grammar section typically has about 50 questions, but this can vary depending on your test setup.

Commonly Confused Words in the HESI A2 Grammar Section

Let’s break down some of the most commonly confused words you might encounter on the HESI A2 grammar section:

Affect vs. Effect

This one’s a classic. “Affect” is usually a verb meaning to influence something, while “effect” is typically a noun referring to the result of an action. If you say, “The new policy will affect productivity,” you’re talking about influencing it. But if you say, “The effect of the new policy was immediate,” you’re referring to the result.

There, Their, and They’re

These words sound the same but have different meanings. “There” refers to a place, “their” indicates possession, and “they’re” is a contraction of “they are.” Mixing these up is a quick way to lose points on the HESI A2 grammar section.

Your vs. You’re

“Your” is possessive, while “you’re” is a contraction for “you are.” It’s easy to confuse these, but the context will give you a clue. If you can replace “you’re” with “you are” and it makes sense, you’re good.

Its vs. It’s

This one is a common mistake. “Its” is possessive, while “it’s” is a contraction for “it is.” If you’re referring to something that belongs to “it,” you use “its.” If you’re saying “it is,” then it’s “it’s.” Get this wrong, and your sentence will sound like nonsense.

To, Too, and Two

“To” is a preposition, “too” means also or excessively, and “two” is the number 2. If you say, “I’m going to the store,” that’s correct. If you say, “I’m going too,” it means you’re also going. If you say, “I bought two apples,” you’re talking about the number.

Than vs. Then

“Than” is used for comparisons, while “then” refers to time or sequence. If you say, “She’s taller than him,” you’re comparing. If you say, “We went to the store, then we went home,” you’re talking about what happened next.
