What Are Defining Relative Clauses?

Defining relative clauses are a type of subordinate clause. They provide information that is necessary to understand the noun they modify.

Imagine you are talking about a specific item. A defining relative clause helps you point out exactly which item you mean.

• The student who got the highest score won a prize. (The clause who got the highest score tells us which specific student.)
• I need to find the book that I borrowed from the library. (The clause that I borrowed from the library tells us which specific book.)

Why Are Defining Relative Clauses Important?

These clauses are crucial for clear communication. They help you avoid confusion and make your descriptions precise.

Without them, your sentences might be too general, and your listener or reader might not understand your exact meaning.

• If you say, "I like the restaurant.", it's not clear which restaurant.
• If you say, "I like the restaurant where we had dinner last night.", it is very clear.

How Do We Form Defining Relative Clauses?

We use relative pronouns or relative adverbs to introduce defining relative clauses. These words connect the clause to the noun it describes.

The choice of pronoun or adverb depends on whether you are talking about a person, a thing, or a place.

• For people, use who oder that.
• For things, use which oder that.
• For places, use where.

When Do We Use 'Who', 'Which', 'That', and 'Where'?

The relative pronoun or adverb you choose depends on the noun you are defining.

• Who: Verwendung who for people. For example, She is the woman who helped me.
• Which: Verwendung which for things or animals. For example, This is the phone which I bought yesterday.
• That: You can use that for both people and things. It is very common in informal English. For example, He is the man that lives next door. oder This is the car that broke down.
• Where: Verwendung where for places. For example, That's the park where we play football.

Can We Omit the Relative Pronoun?

Yes, sometimes you can omit the relative pronoun (who, which, that) in a defining relative clause. This is possible when the pronoun is the object of the clause.

If the pronoun is the subject of the clause, you cannot omit it.

• Pronoun as object (can be omitted):
  This is the book (that) I read last week. (Hier, I is the subject of the clause I read last week, und that is the object.)
• Pronoun as subject (cannot be omitted):
  She is the woman who lives next door. (Hier, who is the subject of the clause who lives next door. You cannot say She is the woman lives next door.)
