Professor Nathan Carr - How to Use Commas with Relative Clauses Do you find it difficult to use commas correctly with relative clauses: who, whom, which, that, or whose? If yes, be happy as Professor Nathan Carr is going to tell you some rules, and these rules will help you put commas correctly with relative clauses. Professor Nathan Carr suggests that Relative clauses are kept in two categories: restrictive clause and non-restrictive clause. The restrictive clause is the clause that provides essential information about the noun about which it talks. You can not eliminate this clause and if you eliminate, the meaning of the sentence would be changed. On the other side, a non-restrictive relative is the clause that provides additional information about the sentence and if you remove this section from the sentence, the meaning of the sentence would not be affected. Professor Nathan Carr shares here three rules about the use of commas with relative clauses. Rule 1: There is no need of any comma with the word “That”. Examples: The house that my brother has built appears awesome. The pen that you gave me yesterday has broken. Rule 2: When relative pronoun is restrictive you need not put a comma. Examples: Are you going to call the boy who broke my pen? Has the pen which you bought for me stolen? Rule 3: When relative pronoun is non-restrictive, you should put comma on both side of the clause. Examples: My tutor, who was from New Delhi, taught me English Grammar. My sister, who has been married to a doctor, would visit us on Christmas. Professor Nathan Carr says that keeping these rules would make it easy for you to use the commas correctly in your sentence, so cram these rules and apply them whenever you use relative clauses in your sentence.
