Understanding Restrictive and Non-Restrictive Clauses

The video tutorial explains the differences between restrictive and non-restrictive clauses. A restrictive clause is essential to the meaning of a sentence, while a non-restrictive clause adds extra information. The tutorial provides guidelines for writing each type of clause, emphasizing the use of 'that' for restrictive clauses without commas, and 'which' for non-restrictive clauses with commas. Examples are provided to illustrate these rules.
