You may worry about getting tripped up on the differences between like and such as, just like many people struggle to remember when to use may vs. might. The good news is you don’t need to worry because, although there are rules regarding how to use like and such as, most writers and editors simply ignore them!

In most cases, writers will use the one that sounds more natural. But although many people consider like and such as interchangeable, there are some subtle differences between them that every writer should know.

Here, we’ll explain whether to use like or such as in a sentence, how to remember their differences, and when to use a comma before them.

Use like whenever you want to make comparisons or create a frame of reference.

The above sentence tells us that Jane appreciates film noir movies that are similar to the two examples provided.

An easy way to remember that like is used to make comparisons is to remember that it performs the same function in similes.

Such as is a phrase that combines the demonstrative pronoun such and the modifier or conjunction as. When put together, they’re used to provide examples or to clarify one’s statement.

Use like to make comparisons or create a frame of reference; use such as when you’re listing specific examples.

A good way to remember how to properly use like or such as in a sentence is to remember that like is used in similes; it’s always used to compare something to something else. Such as can also be another way of saying including, since both can be used to list specific examples.

At the end of the day, however, this is one writing rule that you might be excused for breaking. Such as and like have long been used interchangeably—to the point that many writers will go with whatever sounds best, especially if using the “correct” one breaks their sentence’s flow.

That’s not to say you should disregard the rules between like versus such as all the time, but there are many cases when it’s fine.

Commas need to be used before like and such as only if they’re part of a nonrestrictive clause, which adds information to a sentence but doesn’t necessarily change the sentence’s meaning if it’s removed.
