Idioms are one of the most puzzling parts of the SAT because they don’t necessarily follow any specific grammar rules. It’s almost impossible to logic your way through a question about idioms without any prior knowledge about the phrase in question. It sounds scary, but with the right practice and preparation, even the trickiest idioms will become easier and easier to remember!

In this guide, we’ll strip away the mystery surrounding SAT idioms and provide you with a comprehensive list of common expressions you might see on the exam.

What Are Idioms?

Idioms are basically expressions that don’t conform to the typical rules of a language. In other words, the figurative meaning of an idiom is usually different from the literal meaning of the words in the expression. You often need additional knowledge, especially cultural context, to understand the full meaning of an idiom.

When you think of idioms, your brain probably supplies conversational phrases like “It’s raining cats and dogs” or “I’m all ears.” However, these aren’t the types of idioms that appear in SAT questions. The SAT will evaluate your knowledge on different types of idioms, which we will explore in this guide.

Types of Idioms on the SAT

So, if the SAT doesn’t test you on figurative idioms, what kinds of idioms can you expect to see on the exam? There are 3 types of idioms that appear on the SAT: prepositional idioms, infinitive idioms, and gerund idioms. Let’s break down each one in more detail.

Prepositional Idioms

Prepositional idioms are expressions that require you to use a certain preposition with a given word. There is no set grammar rule that dictates which prepositions accompany which words. You have to be familiar with the phrase to know the correct preposition that belongs in the context of the sentence.

Here’s an example of a sentence that contains an incorrect prepositional idiom: 

• “She was amazed at the breathtaking beauty of the sunset over the ocean.”

Did you catch the mistake? “At” is not the right preposition to pair with the word “amazed.” The correct preposition would be “by,” making the phrase “amazed by.” So, the revised version of the sentence should read:

• “She was amazed by the breathtaking beauty of the sunset over the ocean.”

Even though the original sentence doesn’t violate any specific grammar rules, it does contain an incorrect idiom phrase. You will need to be able to identify similar errors on the SAT.

Infinitive Idioms

Infinitive idioms are expressions that contain a verb followed by the infinitive form of another verb. The infinitive form is the base form of the verb and is always preceded by the word “to” as in the cases of “to sleep,” “to eat,” or “to run.”

Here’s an example of a sentence that contains an incorrect idiom phrase:

• “They agreed to meeting at the café.”

The mistake here is that “agreed” is one of those verbs that should be followed by an infinitive, not a gerund. So, the correct version of the sentence should read:

• “They agreed to meet at the café.”

Gerund Idioms

Gerund idioms are somewhat similar to infinitive idioms. They also contain a verb followed by a different form of another verb, but, instead of an infinitive, these verbs will be followed by a gerund. A gerund is a verb that functions as a noun and usually ends in the suffix “-ing.” Examples of gerunds include “sleeping,” “eating,” and “running.”

Here’s an example of a sentence that contains an incorrect idiom phrase:

• “I enjoy to sleep late on Saturdays.”

The mistake in this sentence is that “enjoy” is a verb that should be followed by a gerund, not an infinitive. So, the correct version of the sentence should read:

• “I enjoy sleeping late on Saturdays.”

Much like with prepositional idioms, there is no rule to determine which verbs are followed by an infinitive and which are followed by a gerund. You just have to be familiar with the expressions and rely on your sense of what sounds right.

Examples of SAT Idioms

Below, you will find a list of idioms you will be likely to encounter on the SAT. We don’t recommend trying to memorize this list, as that will be a big waste of your time that you could spend studying in other ways. Instead, try to familiarize yourself with the expressions on the list. Chances are, there are a lot of expressions on here that you already know, so you can focus on acquainting yourself with the ones you haven’t seen as often.
