What Is the Comma Before "Like"?

First, let’s take a quick look at what the comma before "like" actually does. At its core, the comma's role is to create a pause and separate clauses or phrases for clarity.

Definition list:

• Comma: A punctuation mark (",") used to indicate a pause or separate parts of a sentence.
• Like: A preposition used to compare or give examples, meaning same as "similar to" or "such as."

The question is: Should we always include a comma before "like"? The answer is not always, and how you use it depends on the context and sentence structure.

When Should You Use a Comma Before "Like"?

Now, let’s explore the rules and real-life examples that show you exactly when to add a comma before "like."

1. When "Like" Is Used to Introduce a Nonrestrictive or Extra Information

If the phrase following "like" is non-essential—meaning, it adds extra clarification but isn't vital to the main point—you should use a comma before "like."

Example:

• My dog, like most retrievers, loves water.
  (Here, "like most retrievers" is extra, non-essential info; it could be omitted without destroying the main sentence.)

2. When "Like" Is Used to Make a Comparison in a Nonrestrictive Way

When "like" introduces a comparison that’s non-essential or adds a stylistic touch, a comma helps to set it apart.

Example:

• She dances gracefully, like a professional ballerina.
  (The comparison is additional, not crucial to the main clause.)

3. When "Like" Is Used as an Interjection or Pause

In conversational writing, sometimes a comma is used before "like" as a hesitation or to add emphasis.

Example:

• That’s, like, the best pizza I’ve ever had!
  (It’s more informal and mimics speech patterns.)

When Should You Skip the Comma Before "Like"?

Not all cases call for a comma. Here are situations where no comma is appropriate:

1. When "Like" Is Used as a Restrictive Preposition

In cases where "like" introduces essential information to the sentence, leave out the comma.

Example:

• This painting looks like it was painted by Monet.
  (The comparison is integral to understanding which painting.)

2. When "Like" Is Used to Express a Similarity in a Close Connection

In tight, concise sentences, the comma can feel unnecessary or awkward.

Example:

• She runs like a cheetah.
  (No pause needed; the comparison is direct and essential.)

3. When "Like" Is Part of a Fixed Phrase or Expression

Many idiomatic or set phrases do not require a comma.

Example:

• I’ve never seen anything like it.
  (No comma before "like," since it’s part of the expression.)
