Relative clause 1: who/that/which

Clauses with who/that/which are essential components of English grammar. These clauses can function as the subject or object of a sentence and provide additional information about the noun or pronoun that they modify. Here are some detailed explanations and examples:

1. Who clauses:

Who clauses are used to provide information about a person, and they are introduced by the pronoun "who." These clauses can function as the subject or object of a sentence.

Example: The man who is wearing a red hat is my friend.

In this example, the who clause "who is wearing a red hat" provides information about the man.

2. That clauses:

That clauses are used to provide information about a thing, and they are introduced by the pronoun "that." That clauses can function as the subject or object of a sentence.

Example: The book that I am reading is really interesting.

In this example, the that clause "that I am reading" provides information about the book.

3. Which clauses:

Which clauses are used to provide additional information about a noun or pronoun and are introduced by the pronoun "which." They can function as the subject or object of a sentence.

Example: The car, which is parked outside, belongs to my neighbor.

In this example, the which clause "which is parked outside" provides additional information about the car.

It is important to note that in restrictive clauses, "that" is often used instead of "who" or "which." Restrictive clauses provide essential information about the noun or pronoun and cannot be removed from the sentence without changing its meaning.

Example: The man that is wearing a red hat is my friend.

In this example, the that clause "that is wearing a red hat" provides essential information about the man.

In non-restrictive clauses, "who" or "which" is used to provide additional information that is not essential to the meaning of the sentence. Non-restrictive clauses are set off by commas.

Example: The car, which is parked outside, belongs to my neighbor.

In this example, the which clause "which is parked outside" provides additional information about the car but is not essential to the meaning of the sentence.

Overall, clauses with who/that/which are an important part of English grammar and can greatly enhance the complexity and meaning of a sentence.
