Many students struggle with using commas correctly in academic writing, which can often lead to mistakes and uncertainty. This is usually because they don’t fully understand the rules and exceptions that apply to their use. This article aims to help clarify the appropriate usage of commas before the prepositional phrase “such as”, by providing examples and explaining any exceptions to the rules.
When to place a comma before “such as”
In general, there is only one rule when a comma must be placed before “such as”. This is the case, when “such as” is part of a non-restrictive clause. A non-restrictive clause is additional information that could be omitted without affecting the main meaning of the sentence.

Different Style Guides may have varying rules when it comes to using commas. In addition, certain complex sentences may have exceptions to the standard comma placement rules. It’s important to keep in mind whether a comma is necessary to ensure that your sentence is easy to read and understand.
Comma before “such as”
When the phrase “such as” introduces non-restrictive clauses, a comma is necessary before “such as”.
Non-restrictive clauses
When a non-restrictive clause is introduced by “such as”, a comma should be used to separate the non-essential information from the main sentence. The comma signals to the reader that the information following “such as” is not crucial to the sentence’s core meaning.
Examples
- My favourite hobbies, such as painting and reading, help me relax after a busy day.
- She has travelled to various countries, such as France, Italy, and Japan.
- The playground offers a variety of activities, such as swings and slides.
No comma before “such as”
Generally, no comma is placed before “such as” if the phrase introduces a restrictive clause.
Restrictive clause
Occasionally, “such as” is utilized to introduce a restrictive clause that is imperative in conveying the intended message and identifying the subject matter. Omitting it would result in ambiguity or a less precise statement. It is crucial to keep in mind that restrictive clauses should not be isolated by commas.
Examples
- She is skilled in subjects such as mathematics and physics.
- The store sells products such as electronics and clothing.
- We offer workshops on topics such as communication and leadership.
