What Are "Which" and "That"? An Easy Breakdown
First things first: understanding these words at a basic level is essential. Both "which" and "that" are relative pronouns, used to introduce additional information about a noun in a sentence. But their usage depends on the type of clause they introduce—restrictive or non-restrictive.
Definitions and Key Terms
| Term | Explanation |
|---|---|
| Relative Pronoun | A word that introduces a clause giving more information about a noun. |
| Restrictive Clause | A clause essential to the meaning of the sentence; no commas are used. |
| Non-Restrictive Clause | A non-essential clause providing extra info; set off with commas. |
The Usage of "Which" and "That" in Context
- "That" introduces restrictive clauses. It specifies or defines the noun precisely.
- "Which" introduces non-restrictive clauses, adding extra, non-essential information.
When to Use "That" and "Which": The Rules Explained
Truth be told, the rules for "which" and "that" can seem subtle, but once you understand their roles in sentence structure, it becomes easier to decide which to use.
The Guiding Difference
| Feature | "That" | "Which" |
|---|---|---|
| Use in | Restrictive clauses | Non-restrictive clauses |
| Commas | No commas often needed | Always set off with commas |
| Type of info | Essential details | Extra, non-essential info |
| Example | The book that is on the table is mine. | The book, which is on the table, belongs to me. |
Common Rules and Tips
- Use "that" without commas for restrictive clauses—important info needed to specify the noun.
- Use "which" with commas for non-restrictive clauses—additional info that can be omitted without changing the meaning.
- For formal writing, be consistent with these rules to enhance clarity and professionalism.
Practical Examples and Clarifications
Let’s look at some real-world examples to see these rules in action:
Restrictive Clause with "That"
- The car that broke down was repaired yesterday.
- The students that arrived early received extra credits.
Note: Removing "that" would make the sentence ambiguous.
Non-Restrictive Clause with "Which"
- The car, which was built in Germany, is very reliable.
- The students, which have submitted their assignments, will receive feedback soon.
Note: The info inside commas is additional and can be omitted:
- The car is very reliable.
- The students will receive feedback soon.
Why Is Proper Usage Important?
Using "which" and "that" correctly isn't just about grammar rules; it impacts the clarity of your communication. A misplaced "which" or "that" can confuse readers or change the meaning of your sentences. For example:
- The book that I bought yesterday is missing. (the specific book I bought)
- The book, which I bought yesterday, is missing. (additional info about the book)
Getting these details right enhances readability, professionalism, and your overall writing style.
Tips for Success with "Which" and "That"
- Always identify if the clause is restrictive or non-restrictive.
- Use commas appropriately—no commas for restrictive, commas for non-restrictive.
- Practice by rewriting sentences to see which clause type fits best.
- Read aloud: if the clause can be removed without changing the sentence's core meaning, it’s likely non-restrictive ("which").
- Be consistent in your writing style—formal writing favors strict adherence to these rules.
Common Mistakes and How to Avoid Them
| Mistake | How to Fix It | Explanation |
|---|---|---|
| Using "which" without commas in restrictive clauses | Replace with "that" | Example: "The toys, which are new, are on sale." should be "The toys that are new…" |
| Using "that" in non-restrictive clauses | Use "which" with commas | Example: "The book, that I read, is interesting." should be "The book, which I read, is interesting." |
| Omitting a necessary "that" in a restrictive clause | Add "that" | Example: "The books on the table are mine." → "The books that are on the table are mine." |
Similar Variations and When to Use Them
- "Who" for people: The teacher who/that inspired me…
- "Whom" for objects after prepositions: To whom are you speaking?
- "Where" for places: The city where I was born…
- "When" for time: The day when we met…
Remember, "which" and "that" are just two pieces in the puzzle of relative pronouns.

Properly distinguishing between "which" and "that" isn't just academic; it’s crucial for clear, effective communication. Whether you’re writing an email, a formal report, or just casual notes, mastery over these words improves your writing’s precision and meaning. Moreover, mastering their use can give your language a polished, professional touch.
