Relative Pronouns and Case

After you have identified the type of noun that the relative pronoun will be referring to (person or object), it is also important to select the appropriate pronoun by deciding the case in which being used: subjective, objective, or possessive.

When needing a relative pronoun to the subject of the sentence, be sure to use the subjective form:

  • The girl who made the dress.
    • Who = relates to girl which is the subject

When the relative pronoun connects to the object of the sentence use the objective case:

  • The girl whom you love.
    • In this sentence, the girl is the object of your love; therefore, the objective form is used.

When the relative pronoun is used in a manner of ownership, the possessive form is used:

  • The girl whose heart was broken.
    • In this sentence the heart belongs to the girl; therefore, the possessive form, whose, is used.

Relative Pronouns and Relative Clauses

Relative clauses provide more information about a noun in a sentence. Relative pronouns introduce the relative clause.

If the relative clause is needed to identify the person or object, this is called an essential relative clause, and commas are not required.

  • The girl who lives next door is shy.
    • Who lives next door = essential relative clause
    • Girl is a vague noun and the essential clause is essential in the sentence for understanding.

However, if the relative clause is just providing additional information about the person or object, it is considered a non-essential relative clause and, commas are needed to separate it.

  • Lee, who owns the pastry shop, is a friendly woman.
    • Who owns the pastry shop = non-essential relative clause
    • In this sentence, the relative clause is providing extra information about Mrs. Lee.

Relative Adverbs

Relative adverbs are also used to provide more information about a noun. There are three relative adverbs:

The relative adverb where gives more information about a place:

  • Let’s go the park where there are lots of trees.
    • Where = gives more information about a place, the park

The relative adverb when refers to time:

  • Summer is when we have the most fun as a family.
    • When = gives more information about a time, summer

The relative adverb why gives more information about a reason:

  • I don’t know the reason why your brother has so much energy.
    • Why = gives more information about the unknown reason
