"Relative Adverbs" in the English Grammar

What Are Relative Adverbs?

Relative adverbs are adverbs that are used to introduce a dependent clause that functions as a modifier within a sentence. These adverbs are called relative because they relate the dependent clause to the rest of the sentence.

English Relative Adverbs

There are three main relative adverbs in English:

1.

When → refers to time

2.

Where → refers to place

3.

Why → refers to reason

Tip!

A relative adverb can usually be replaced by a preposition and the relative pronoun 'which' (for example, 'in which,' 'for which,' 'on which,' etc.)

Relative Adverbs: Function

Relative adverbs are used to introduce and head a relative clause, which functions as a modifier for a noun or pronoun in a sentence to provide additional information about it. Consider these sentences:

Example

This is the hospital.

My mom gave birth to me.

They are both correct sentences, but if we want to join them to form a single sentence, we need a relative adverb:

Example

This is the hospital where my mom gave birth to me.

Relative Adverb of Time

'When' is a relative adverb of time that is commonly used to introduce relative clauses that relate to time. It can replace more formal phrases, such as 'in which', 'at which', or 'on which.' Here are some examples:

Example

I remember the day when I met your mother.

You can also say "I remember the day on which I met your mother."

Do you remember the years when our country was not at war?

Relative Adverb of Place

'Where' is a relative adverb of place that is commonly used to introduce relative clauses that relate to location. It can replace more formal phrases, such as 'in which' or 'at which.'
Here is a list of all the relative adverbs of place:

where

whereon (archaic)

wherein (formal)

Example

This is the restaurant where we had out first date.

Or "this is the restaurant in which we had our first date."

This is the place where we took these photos.

These are the streets whereon we walked as young men.

I visited him in the city wherein he lives.

Relative Adverb of Reason

'Why' is a relative adverb of reason that is commonly used to introduce relative clauses that relate to the reason for something. It can replace the more formal phrase 'for which' and is used to provide additional information about the cause or motivation behind an action or event in a sentence. For example:

Example

The reason why this has become a problem is still unknown to us.

I don't see a reason why they cannot get married.
