Connecting ideas in English becomes much smoother when you know how to use relative pronouns correctly. These small but powerful words allow you to combine independent clauses into longer, more detailed, and more natural-sounding sentences without repeating the same nouns over and over.
What are the three types of relative pronouns?
Relative pronouns fall into three main categories depending on the role they play in the sentence [0:24]:
- Subject relative pronouns: they refer to the person or thing performing the action (who, which, that).
- Object relative pronouns: they refer to the person or thing receiving the action (who, whom, which, that).
- Possessive relative pronouns: they indicate ownership or a relationship between people or things (whose).
Notice that who, which, and that can work as both subject and object relative pronouns. The key difference is understanding what role the noun plays in the connected clause.
How does "who" work as a subject relative pronoun?
Consider two independent clauses: "Michael Jackson was a singer" and "He wrote the song Billie Jean." Each one makes perfect sense on its own. However, you can fuse them into a single, natural sentence [2:15]:
"Michael Jackson was a singer who wrote the song Billie Jean."
Here, who replaces the repeated subject and refers directly to Michael Jackson. You can even keep adding information using commas to separate the extra details: "Michael Jackson, who wrote the song Billie Jean, received 13 Grammy awards." The commas help the reader pause and process each piece of information, making your message more effective and well-structured [3:10].
When should you use "which" and "that" instead?
Both which and that refer to objects, things, animals, or non-animated elements [4:05]. Look at this example:
- "She lives in an old house." + "The house was built in 1954."
- Combined: "She lives in an old house, which was built in 1954."
Which here refers to the house, not to the person. You could also say that and it would be perfectly correct. Another example [5:00]:
- "This is the homework." + "You need to turn in your homework on Monday."
- Combined: "This is the homework that you need to turn in on Monday."
The relative pronoun eliminates the repetition and keeps the sentence flowing naturally.
What is the difference between "whom" and "whose"?
Whom is an object relative pronoun that refers to a person receiving the action [5:45]. For instance:
- "This is Jack." + "You met Jack at the party."
- Combined: "This is Jack, whom you met at the party."
In this case, whom refers to Jack as the object because "you" is the subject who performed the action of meeting. That said, whom sounds more formal and is less common in everyday English nowadays. Using who instead is perfectly acceptable in most situations.
Whose, on the other hand, is the only possessive relative pronoun [6:45]. It signals ownership or a relationship:
- "This is Emily." + "I studied with Emily's sister."
- Combined: "This is Emily, whose sister studied with me."
Here, whose does not refer to Emily directly but to her sister, indicating the possessive connection between Emily and the sister.
How do "when", "where", and "why" connect ideas?
Beyond the classic relative pronouns, three additional words help you connect clauses when talking about times, places, and reasons [8:20].
- When is used for times: "There isn't a day when I don't feel tired." The pronoun refers to the day, not to the feeling.
- Where is used for places: "I know a restaurant where the food is really tasty." It points to the restaurant, providing clearer information than that or which would [9:05].
- Why is used for reasons: "I don't know the reason why you are always late." It connects directly to the reason being mentioned [9:35].
Using when, where, and why instead of generic pronouns makes your sentences more precise and easier to understand.
The best way to master relative pronouns is through repetition and practice. Try writing your own sentences using who, which, that, whose, whom, where, when, and why to combine independent ideas into single, well-connected statements. Share your examples and exchange feedback with others to reinforce what you have learned.
