Non-restrictive Clause
What Is a Non-restrictive Clause?
A non-restrictive clause is a clause that provides additional, non-essential information. In other words, a non-restrictive clause is not needed to identify the word it modifies, i.e., it's just bonus information.As a non-restrictive clause is not essential to the meaning of a sentence, it is offset with commas. For example:
- I went to London with John Baker, who lives next door. (The shaded text is just additional information. It is a non-restrictive clause.)
- Betty, who is still on the ferry, will arrive before 4 o'clock. (This is just additional information. It is a non-restrictive clause.)

Non-restrictive Clauses vs Restrictive Clauses
Here is another example of a non-restrictive clause.- Peter Jones , who plays goalkeeper for our village football team, has worked at his father's greengrocers for twenty years. (The shaded text is a non-restrictive clause. It describes "Peter Jones," but it does not identify him. It is merely additional information about him. Deleting this clause would not affect the meaning.)
- The man who plays goalkeeper for our village football team has worked at his father's greengrocers for twenty years. (The bold text is a restrictive clause. It describes "the man," and it identifies him. It is not just additional information. It is essential for meaning.)
Your Choice of Punctuation
You are not limited to commas when offsetting a non-restrictive clause. You can use parentheses (brackets) or dashes too. (See Reason 2 below.) Read more about your choices of punctuation for offsetting a non-restrictive clause.More Examples of Non-restrictive Clauses
Here are some more examples of non-restrictive clauses in real-life quotations (non-restrictive clauses shaded):- Every journalist has a novel in him, which is an excellent place for it. (Historian Russell Lynes)
- Humans are the only animals that have children on purpose with the exception of guppies, who like to eat theirs. (Journalist P J O'Rourke)
- She had a pretty gift for quotation, which is a serviceable substitute for wit. (Playwright W. Somerset Maugham)
- You can talk about anything if you go about it the right way, which is never malicious. (comedian Rodney Carrington)
Why Non-restrictive Clauses Are Important
When looking at writing errors, there are more issues associated with restrictive clauses than non-restrictive clauses. As a general observation, non-restrictive clauses do not cause too many snags. Nevertheless, here are two good reasons to give non-restrictive clauses a little more thought.(Reason 1) Know when to use a comma before "who" or "which."
Writers often ask whether to put a comma before "who" and "which." The answer to that question is sometimes yes and sometimes no. It depends whether the "who" or "which" heads a restrictive clause or a non-restrictive clause.Look at this example:
- My brother, who lives in New York, caught coronavirus. (This sentence suggests I have just one brother. I've also told you that he lives in New York, but I could have omitted that information. The shaded text is a non-restrictive clause.)
- My brother who lives in New York caught coronavirus. (In this sentence, the bold text is a restrictive clause. It specifies that I'm talking about my New York-based brother, i.e., not a different brother.)
- I've enjoyed the benefits of this country, which has been very good to me. (Attorney Wendy Long) (This is non-restrictive clause. It does not define the country (the word "this" does that job). The shaded clause is just additional information.)
- How can you govern a country which has 246 varieties of cheese? (French President Charles De Gaulle) (This is a restrictive clause. It defines the country. Those following British English writing conventions are okay with a restrictive clause headed by "which," but most Americans would use "that" instead of "which."
(Reason 2) Know when to use a comma before "who" or "which."
Commas are the most common type of parenthetical punctuation, but, for certain effects, you can use others. Here are some guidelines:Parenthetical Punctuation | |
---|---|
commas |
(pro) normal-looking sentence (con) commas are often confused with other commas in the sentence |
brackets |
(pro) parenthesis easily seen (con) brackets make official letters look a little unorganized |
dashes |
(pro) parenthesis easily seen (con) dashes look a little stark |
Key Points
- Do you have an adjective clause headed by "which" or "who"? Would you happily put it in parentheses? Yes? It's non-restrictive. Offset it with commas or, if you think it helps, dashes or parentheses (round brackets).
- Knowing your options for parenthetical punctuation is a useful writing tool.
