When to Use “That” vs. “Which”—Explained Simply

Ah, the joys of the English language! Whether you’re writing an essay, crafting a compelling blog post, or just trying to impress your friends with your grammatical prowess, you might find yourself at a crossroads when deciding between “that” and “which.” Fear not! Today, we’re unpacking this tricky grammar conundrum in a way that’s both educational and entertaining. Let’s dive into the delightful world of conjunctions!

The Basics: What’s the Difference?

At its core, “that” and “which” are both relative pronouns, meaning they introduce relative clauses—those handy little clauses that provide additional information about a noun. But here’s the twist: they serve different purposes in the sentences they inhabit.

In simple terms:

• “That” is used for essential clauses.
• “Which” is used for nonessential clauses.

Confused? Don’t worry; we’ll break it down further!

Essential vs. Nonessential Clauses: The Key to Understanding

Let’s dissect those essential and nonessential clauses a bit more.

Essential Clauses

An essential clause (also known as a restrictive clause) is crucial for understanding the meaning of the sentence. Without it, the sentence loses its intended meaning. Think of it as the “must-have” information.

Example:

• The book that I borrowed from you is fantastic.

In this sentence, the clause “that I borrowed from you” tells us which specific book we’re talking about. If we removed it, we’d just be left with “The book is fantastic,” which doesn’t clarify which book we mean.

Nonessential Clauses

On the other hand, a nonessential clause (or nonrestrictive clause) provides extra information that can be omitted without changing the meaning of the sentence. It’s like the icing on the cake—nice to have but not necessary for the cake to exist!

Example:

• My favorite book, which I borrowed from you, is fantastic.

Here, “which I borrowed from you” adds additional information about the book but isn’t essential. Even if we took it out, we’d still know what book the speaker is referring to: “My favorite book is fantastic.”

The Comma Conundrum

Here’s a handy tip to help you remember which to use: commas!

• If you can remove the clause without losing the core meaning of the sentence, use “which” and include commas.
• If the clause is essential to the sentence’s meaning, use “that” without commas.

Example Breakdown

Let’s break down one more example to solidify your understanding:

• I visited the museum that showcases ancient artifacts.

In this case, the clause “that showcases ancient artifacts” is essential. Without it, we wouldn’t know which museum is being referred to.

• I visited the museum, which is my favorite place to relax.

Here, the clause “which is my favorite place to relax” is nonessential. It adds detail but isn’t critical to understanding which museum was visited.

The Exceptions: When Grammar Gets a Little Crazy

As with most rules in English, there are exceptions! In American English, “that” and “which” are typically used in the ways we’ve outlined. However, in British English, “which” can sometimes be used in situations where American English would prefer “that.”

For example:

• The car that is parked outside is mine. (American English)
• The car which is parked outside is mine. (British English)

While these variations are interesting, it’s good to stick to the rules we discussed, especially if you’re writing for an audience that might expect American English conventions.

Real-Life Applications: Why It Matters

Now that you’re armed with the knowledge of how to use “that” and “which,” let’s explore why this distinction matters in real-life writing scenarios.

Professional Writing

Whether you’re drafting an email to your boss or writing a report, clarity is key. Using “that” and “which” correctly can enhance your professionalism and ensure your ideas are conveyed accurately.

Academic Writing

For students and researchers, mastering this distinction can elevate your writing and help you avoid common pitfalls that could lead to confusion or misinterpretation of your arguments.

Everyday Conversations

Even in casual conversation, knowing when to use “that” versus “which” can help you express your thoughts more clearly, making your points easier for others to grasp.
