Have you ever found yourself staring at a sentence, wondering how to add just a little more detail without making it sound clunky? That's where relative clauses come in, and honestly, they're not as intimidating as they might sound. Think of them as your sentence's helpful sidekick, always ready to offer extra information about a noun.
At their heart, relative clauses are dependent clauses. This means they have a subject and a verb, but they can't stand on their own as a complete thought. They're like a fascinating anecdote that needs a main story to attach itself to. And the magic ingredient that kicks them off? Relative pronouns: who, whom, whose, that, and which.
These little words are crucial because they stand in for a noun or pronoun, linking the clause back to the main part of the sentence. For people, we often reach for 'who' when it's acting as the subject (like in 'The person who called was very polite') or 'whom' when it's the object (as in 'The person whom I met was friendly'). 'Whose' is the go-to for showing possession, whether it's a person or a thing ('The student whose project was outstanding received an award').
When we're talking about things, or sometimes people, 'that' and 'which' step onto the stage. 'That' is a bit of a workhorse; it can be used for both subject and object roles, but it's generally reserved for what we call restrictive clauses. 'Which' can also be used for subject or object, and it's the star player in non-restrictive clauses, though it can pop up in restrictive ones too – though some folks prefer to stick with 'that' there.
The Two Flavors: Restrictive vs. Non-Restrictive
This is where things get really interesting, and understanding the difference is key to using 'that' and 'which' correctly.
Restrictive Relative Clauses: These are the essential ones. They provide information that is absolutely necessary to identify the noun they're describing. Without them, you wouldn't know which noun we're talking about. Imagine saying, 'I like the paintings.' Which paintings? We need more info! So, you'd add a restrictive clause: 'I like the paintings that hang in the SASB North lobby.' See? Now we know exactly which paintings you mean. Because they're so vital, we don't use commas to set them off. For people, we use 'who' or 'that'; for things, 'that' or 'which' (though 'that' is often preferred).
Non-Restrictive Relative Clauses: These are more like friendly additions, offering extra, interesting details but not essential for identifying the noun. The noun is already clear on its own. Think of it like this: 'My mother is an excellent cook.' If you're already talking about your mother, she's pretty clearly identified. So, you can add a non-restrictive clause: 'My mother, who is an excellent cook, is thinking of opening a restaurant.' Notice the commas? They're the signal that this is extra info. And a big rule here: you cannot use 'that' in non-restrictive clauses. It has to be 'who,' 'whom,' 'whose,' or 'which.'
Making Sentences Sing: Reducing Clauses
Sometimes, you might want to make your writing more concise or add a bit of variety. Relative clauses can often be shortened, or 'reduced.' For restrictive clauses, if the relative pronoun is the subject, you can often drop it and add '-ing' to the verb: 'The paintings that hang in the lobby' becomes 'The paintings hanging in the lobby.' If the relative pronoun is the object, you can often just delete it: 'The bike that my father gave me' becomes 'The bike my father gave me.'
Non-restrictive clauses can also be reduced, usually by dropping the relative pronoun and the 'be' verb: 'My mother, who is an excellent cook...' can become 'My mother, an excellent cook...' (though this is a bit more advanced and can sometimes change the nuance).
So, the next time you're writing, don't shy away from these handy clauses. They're powerful tools for adding depth and clarity, making your sentences flow more naturally and your ideas shine.
