Relative Pronouns

Relative Pronouns
There are five relative pronouns: who, whom, whose, which, that*

Relative Pronouns

You can use a relative pronoun is used to link one phrase or clause to another phrase or clause. The relative pronouns are "who," "whom," "that," and "which." The compounds "whoever," "whomever," and "whichever" are also relative pronouns.

You can use the relative pronouns "who" and "whoever" to refer to the subject of a clause or sentence, and "whom" and "whomever" to refer to the objects of a verb, a verbal or a preposition.

In each of the following sentences, the highlighted word is a relative pronoun.

You may invite whomever you like to the party.

The relative pronoun "whomever" is the direct object of the compound verb "may invite."

The candidate who wins the greatest popular vote is not always elected.

In this sentence, the relative pronoun is the subject of the verb "wins" and introduces the subordinate clause "who wins the greatest popular vote." This subordinate clause acts as an adjective modifying "candidate."

In a time of crisis, the manager asks the workers whom she believes to be the most efficient to arrive an hour earlier than usual.

In this sentence "whom" is the direct object of the verb "believes" and introduces the subordinate clause "whom she believes to be the most efficient". This subordinate clause modifies the noun "workers."

Whoever broke the window will have to replace it.

Here "whoever" functions as the subject of the verb "broke."

The crate which was left in the corridor has now been moved into the storage closet.

In this example "which" acts as the subject of the compound verb "was left" and introduces the subordinate clause "which was left in the corridor." The subordinate clause acts as an adjective modifying the noun "crate."

I will read whichever manuscript arrives first.

Here "whichever" modifies the noun "manuscript" and introduces the subordinate clause "whichever manuscript arrives first." The subordinate clause functions as the direct object of the compound verb "will read."

Relative Pronouns

The relative pronouns (who/whoever/which/that) relate groups of words to nouns or other pronouns (The student who studies hardest usually does the best.). The word who connects or relates the subject, student, to the verb within the dependent clause (studies). Choosing correctly between which and that and between who and whom leads to what are probably the most Frequently Asked Questions about English grammar. For help with which/that, refer to the Notorious Confusables article on those words (including the hyperlink to Michael Quinion's article on this usage and the links to relevant quizzes). Generally, we use "which" to introduce clauses that are parenthetical in nature (i.e., that can be removed from the sentence without changing the essential meaning of the sentence). For that reason, a "which clause" is often set off with a comma or a pair of commas. "That clauses," on the other hand, are usually deemed indispensable for the meaning of a sentence and are not set off with commas. The pronoun which refers to things; who (and its forms) refers to people; that usually refers to things, but it can also refer to people in a general kind of way. For help with who/whom refer to the section on Consistency. We also recommend that you take the quizzes on the use of who and whom at the end of that section.

The expanded form of the relative pronouns — whoever, whomever, whatever — are known as indefinite relative pronouns. A couple of sample sentences should suffice to demonstrate why they are called "indefinite":

The coach will select whomever he pleases.
He seemed to say whatever came to mind.
Whoever crosses this line first will win the race.

What is often an indefinite relative pronoun:

She will tell you what you need to know.
