Which Sentence Includes a Nonrestrictive Clause?
Ever stared at a sentence and wondered why a certain part feels like a side note? That “side note” is often a nonrestrictive clause. It’s the secret sauce that adds flavor without changing the core meaning. In this post, I’ll tell you exactly what a nonrestrictive clause is, how to spot it, and why you should pay attention to it. By the end, you’ll be able to spot and use them like a pro.
What Is a Nonrestrictive Clause?
A nonrestrictive clause is a group of words that gives extra information about a noun or pronoun but isn’t essential to the sentence’s meaning. Think of it as a polite aside: it tells you more, but if you skip it, the sentence still works.
Key Traits
- Punctuation – Nonrestrictive clauses are set off by commas (or dashes in informal writing).
- Pronoun or relative word – They often start with who, whom, whose, which, or that (though that is usually restrictive, so watch out).
- Optional information – If you remove the clause, the sentence still makes sense and keeps its original intent.
A Quick Test
Take the sentence:
My brother, who lives in New York, is coming to visit.
Remove the clause: *My brother is coming to visit.So *
The sentence still works. The clause didn’t change the core meaning; it just added a detail.
Why It Matters / Why People Care
Clear Communication
When you use commas correctly, you let readers know which bits are essential and which are extras. Misplacing commas can turn a harmless sentence into a confusing mess Which is the point..
Writing Style
Nonrestrictive clauses give your prose a conversational tone. They let you drop facts, anecdotes, or clarifications without breaking the flow.
Grammar Tests and Exams
If you’re studying for the SAT, ACT, or any certification, you’ll see nonrestrictive clauses in the grammar sections. Knowing the difference between restrictive and nonrestrictive clauses can earn you those extra points.
How It Works (or How to Do It)
Let’s break it down step by step. I’ll use a mix of examples and explanations so you can see the rule in action.
1. Identify the Core Statement
Start with the main clause – the sentence without any extra bits.
Core: The mayor announced a new policy.
2. Add a Nonrestrictive Clause
Insert a clause that adds detail but doesn’t alter the core meaning That's the part that actually makes a difference..
With Clause: The mayor, who was elected last year, announced a new policy.
Notice the commas. They tell you that “who was elected last year” is optional.
3. Check the Pronoun
Nonrestrictive clauses usually start with who, whom, whose, which, or that (rarely that). If you see who or which, you’re likely looking at a nonrestrictive clause.
The book, which I bought yesterday, is already a bestseller.
4. Test by Removing the Clause
Remove the clause and see if the sentence still makes sense.
The book is already a bestseller. – Still works Simple, but easy to overlook..
If it doesn’t, you were looking at a restrictive clause Easy to understand, harder to ignore..
5. Use Commas Correctly
- Nonrestrictive: She loves hiking, especially in the Rockies.
- Restrictive: She loves hiking in the Rockies. (No commas – “in the Rockies” tells us which hiking she loves.)
Common Mistakes / What Most People Get Wrong
1. Forgetting the Commas
My friend who lives in Paris is a chef.
My friend, who lives in Paris, is a chef.
The first version reads like a single, confusing sentence. The second is clear.
2. Using “That” Instead of “Which”
*The car that I bought is red.Still, * (Restrictive – tells us which car. On the flip side, )
*The car, that I bought, is red. * (Wrong – should be which.
3. Confusing “Which” with “Who”
- Who refers to people.
- Which refers to objects or ideas.
The teacher, who is very strict, never smiles.
The teacher, which is rare for this school, never smiles. (Incorrect; should be who Turns out it matters..
4. Over‑Comma‑ing
The dog, which was brown, with spots, and huge, barked loudly.
The dog, which was brown with spots and huge, barked loudly.
Too many commas make the sentence feel choppy. Keep it tidy.
5. Misplacing the Clause
*She likes to read, her favorite genre is science fiction.Because of that, *
*She likes to read, her favorite genre is science fiction. * (Missing comma between clauses.
Practical Tips / What Actually Works

- Practice with Real Sentences – Take news articles or blog posts and highlight nonrestrictive clauses.
- Keep a “Comma Diary” – Note down sentences where you’re unsure, then check them later.
- Ask for Feedback – Share a paragraph with a friend or colleague and see if they spot the clause.
