Relative Clauses Examples: Correct and Incorrect
Side-by-side examples of relative clauses done right and wrong.
Correct and incorrect relative clauses
Relative clauses are best learned through paired examples. The tables below show incorrect sentences next to corrected versions, with a note on what changed. Read the incorrect version to feel the error, then the correct one to see the fix.
These examples cover pronoun choice, comma placement, and verb agreement, the three areas where relative clauses most often go wrong.
Pronoun and comma examples

|---|---|---|
| The student which won the prize is here | The student who won the prize is here | who for a person |
| My brother that lives in Paris called | My brother, who lives in Paris, called | non-defining, needs commas and who |
| The car, that I bought, is red | The car that I bought is red | defining clause, no commas |
| The book who I read was long | The book that I read was long | that or which for things, not who |

| Incorrect | Correct | Reason |
|---|---|---|

If removing the clause changes which noun you mean, it is defining and takes no commas. If removing it leaves the meaning intact, it is non-defining and takes commas. This test resolves almost every punctuation question.

Examples build reliable instinct
After working through these examples, relative clause choices start to feel obvious. You develop an ear for when a clause needs commas and which pronoun fits. Keep a few corrected pairs handy for reference during edits.

Precision through controlled clauses
Relative clauses let you deliver detail efficiently, but only when each clause attaches to one clear noun. The discipline is to read each clause and confirm it has a single, obvious antecedent. When a clause could describe two nouns, the reader guesses, and guessing is where confusion begins.
In longer work, the temptation is to stack clauses for density. Resist it. Two short sentences with one clause each usually read more clearly than one long sentence with three clauses chained together. Clarity is the goal, and splitting often serves it better than compressing.
After every who, which, or that, name the noun it describes. If you cannot name one without hesitating, the clause is ambiguous. Move it closer to its noun or split the sentence so the relationship is unmistakable.
