What Is a Noun Clause?
A noun clause is a dependent clause that functions as a noun within a sentence. It can act as a subject, object, complement, or object of a preposition. Because it behaves like a noun, it can be replaced by a noun or pronoun in many contexts.
Typical structures that introduce noun clauses include:
| Conjunction / Relative Pronoun | Example | Function in the sentence |
|---|---|---|
| that | I know that he will come | Object of know |
| if / whether | She is unsure if she will join | Object of unsure |
| wh‑words (who, what, where, when, why, how) | I wonder what he means | Object of wonder |
| because, although, after, before, since, unless, while | They left because it was raining | Object of left |

Note that the clause is dependent; it cannot stand alone as a complete sentence Most people skip this — try not to..
Why Underline Noun Clauses?
Underlining noun clauses is a useful exercise for:
- Identifying clause boundaries – Helps you see where the clause starts and ends.
- Understanding sentence structure – Clarifies how the clause functions within the larger sentence.
- Improving editing skills – Makes it easier to spot misplaced modifiers or dangling phrases.
In educational settings, teachers often ask students to underline noun clauses to reinforce grammatical awareness. The same technique can be applied in proofreading, essay writing, or even creative writing to ensure clarity Simple, but easy to overlook..
Step‑by‑Step: How to Underline a Noun Clause
Follow these steps to locate and underline noun clauses in any sentence:
1. Look for Subordinating Conjunctions or Relative Pronouns
Scan the sentence for words such as that, if, whether, who, what, where, when, why, how, because, although, since, unless, while, etc. These words often signal the start of a clause.
2. Confirm It Is a Clause
A clause must contain at least a subject and a verb. If the segment after the conjunction includes both, you’re likely looking at a clause.
3. Check Its Function
Ask yourself: What role does this clause play?
- Subject: What you do matters.
- Object: *I know that you’re right.Think about it: *
- Complement: *The problem is why we failed. *
- Object of a Preposition: *She is concerned about what will happen.
If it answers one of these roles, it’s a noun clause Turns out it matters..
4. Underline the Entire Clause
Underline from the first word of the conjunction to the last word of the clause, including any internal punctuation.
5. Verify No Other Clause Is Inside
Sometimes a noun clause contains another clause (a subordinate clause). Only underline the outermost clause unless the exercise specifies otherwise That's the part that actually makes a difference..
Practice Examples
Below are ten sentences with noun clauses highlighted. Try underlining them yourself before checking the answers.
| # | Sentence | Noun Clause (Underlined) |
|---|---|---|
| 1 | *I don’t know what you are thinking.Also, * | as soon as the funding arrives |
| 7 | *I’m worried that he won’t come. On top of that, * | how the city developed |
| 6 | *We will finish the project as soon as the funding arrives. Think about it: * | that the plan will succeed |
| 9 | *She forgot who called her last night. * | whether we could help |
| 5 | The book is about how the city developed over the last century. | why the meeting was canceled |
| 4 | They asked whether we could help. | that he won’t come |
| 8 | *There is no doubt that the plan will succeed.Even so, * | if he apologizes |
| 3 | *It is unclear why the meeting was canceled. * | what you are thinking |
| 2 | She will accept if he apologizes. | who called her last night |
| 10 | *It is obvious that the evidence is missing. |
Tip: When you underline, keep the punctuation attached to the clause. Take this: "I don’t know what you are thinking." includes the period after thinking as part of the clause, but you can underline just the clause itself without the period if the instruction allows.
Common Mistakes to Avoid
| Mistake | Why It Happens | How to Correct |
|---|---|---|
| Underlining only the conjunction | That or if seems to be the whole clause. Day to day, | Include the subject and verb that follow. Also, |
| Skipping embedded clauses | Inside a noun clause, another clause may exist. | Decide whether the exercise wants the outer clause only or both. Day to day, |
| Over‑underlining | Thinking the entire sentence is a clause. | Remember a clause must have a subject and verb. |
| Misidentifying relative clauses | The book that I read was good. | This is a relative clause (adjective clause), not a noun clause. |
