The Yellow Light Predicament

It’s a lot like driving through a yellow light. As you drive through, you wonder—should you have stopped? Using the phrase Such As can leave a person wondering, too. Should you have used a comma before Such As? Should you have the comma out? Should you forget writing and take up knitting?

Well, there is no need to “yellow light” this phrase anymore. There is an easy way to tell whether to use a comma. No, we’re not kidding. Ready?

  • Question:

Do I put a comma before such as?

  • Answer:

Yes—IF the phrase is a part of, or connected to, a nonrestrictive clause.

  • Question:

What in the world did you just say?

  • Answer:

If such as could be dropped and the sentence still says a truthful statement, then put a comma in front. It’s just more fun saying it with big words.

Comma Before Such As | Examples

Here are some examples:

  • Correct: The aquarium held many types of fish, such as angelfish and rainbowfish.

The phrase, “such as angelfish and rainbowfish” is nonrestrictive.

  • Correct: At the restaurant, they offered hot drinks, such as coffee and hot chocolate.

The phrase, “such as coffee and hot chocolate” is nonrestrictive. What does that mean? It means if you remove that phrase, the sentence would still be true.

  • The aquarium held many types of fish
  • At the restaurant, they offered hot drinks

When NOT to Use a Comma Before Such As

  • Correct: Birds such as the penguin and ostrich don’t fly.

This is a restrictive phrase after such as. So we don’t put a comma before such as. It is restrictive because if we were to remove the phrase, “such as the penguin and ostrich”, we would wind up with a sentence that isn’t true. The sentence would end up saying, “Birds don’t fly”, and birds do fly. Well, many do, anyway.

Such As is a handy little phrase, not limited to talking about birds and fish. It is often used in writing to give examples.

  • Correct: Large houses, such as farm-style ranch houses, were popular in the 1940’s.
  • Correct: Some herbal plants, such as peppermint and rosemary, have been around for centuries.

Don’t forget! If the comma is before Such As, it means that if the phrase were to be taken out, the sentence would remain truthful. So, large houses would have still been popular back in the 1940’s. Also some herbal plants have been around for centuries…

When using Such As for an example, remember the restrictive rule.:

  • Correct: Fabrics such as nylon do not breathe well in warm weather.

Restrictive—no comma; Nonrestrictive—comma. Sometimes life is so easy, it almost hurts.

When To Use A Comma Before “Such As” — Practice Quiz

1 / 5
Q1

Question 1: Which sentence correctly uses a comma before "such as"?

Question 1 options
"The aquarium held many types of fish, such as angelfish and rainbowfish" is correct because the phrase after "such as" is nonrestrictive — removing it still leaves a true statement. In "Birds such as the penguin and ostrich don't fly," the phrase is restrictive and no comma is needed.
Q2

Question 2: You should always place a comma before "such as" when it introduces examples in a sentence.

Question 2 options
This is false. A comma before "such as" is only used when the phrase is nonrestrictive (removable without changing the truth of the sentence). When the phrase is restrictive — meaning removing it would make the sentence untrue — no comma is used.
Q3

Question 3: Why is there NO comma before "such as" in the sentence "Birds such as the penguin and ostrich don't fly"?

Question 3 options
The phrase "such as the penguin and ostrich" is restrictive because removing it would leave "Birds don't fly," which is not true. A restrictive phrase is essential to the meaning, so no comma is used.
Q4

Question 4: Match each sentence with the correct comma rule for "such as".

Question 4 options
They offered hot drinks, such as coffee and hot chocolate.
Fabrics such as nylon do not breathe well.
Large houses, such as farm-style ranch houses, were popular.
Birds such as the penguin and ostrich don't fly.
Nonrestrictive — removable phrase
Restrictive — essential phrase
Restrictive — no comma needed
Nonrestrictive — comma needed

Select an item on the left, then tap its match on the right.

Nonrestrictive phrases (removable without changing truth) need a comma: hot drinks and large houses sentences remain true without the examples. Restrictive phrases (essential to truth) have no comma: "Fabrics don't breathe well" and "Birds don't fly" would be false without the examples.
Q5

Question 5: Some herbal plants ___ peppermint and rosemary, have been around for centuries.

Question 5 options
The correct answer is ", such as" with a comma because the phrase is nonrestrictive. Removing "such as peppermint and rosemary" still leaves the true statement "Some herbal plants have been around for centuries."
