Explain the concept of restrictive and non-restrictive clauses.

Restrictive clauses, also known as essential or defining clauses, provide essential information about the noun they modify. They are necessary for the sentence to make sense and cannot be removed without changing the meaning of the sentence. Restrictive clauses are not set off by commas.

Non-restrictive clauses, also known as non-essential or non-defining clauses, provide additional information about the noun they modify. They are not necessary for the sentence to make sense and can be removed without changing the meaning of the sentence. Non-restrictive clauses are set off by commas.
