When To Use That Or Which In A Sentence

Imagine you're describing your favorite coffee shop. Do you say, "The coffee shop that sells amazing lattes is my favorite," or "The coffee shop which sells amazing lattes is my favorite?" While both might sound acceptable, the subtle difference between "that" and "which" can significantly impact the clarity and meaning of your sentences. Mastering this distinction elevates your writing from good to great, ensuring your message is precise and easily understood.

The correct usage of "that" and "which" often trips up even seasoned writers. It's not merely about grammatical correctness; it's about conveying the intended meaning effectively. Using "that" and "which" correctly clarifies whether the information you're adding is essential to the sentence or simply extra information. Let's unravel the mystery behind these two words, exploring their roles in sentence construction and providing you with the knowledge to use them with confidence.

Main Subheading

The words "that" and "which" are relative pronouns that introduce clauses providing more information about a noun. The key difference lies in whether the clause is restrictive (essential) or nonrestrictive (non-essential). Understanding this distinction is crucial for mastering the correct usage. A restrictive clause is essential to the meaning of the sentence and cannot be removed without altering the sentence's core meaning. In contrast, a nonrestrictive clause provides additional information that is not crucial to the sentence's core meaning and can be removed without affecting the sentence's basic meaning.

Think of it this way: if the information is vital for identifying the noun being discussed, then you likely need "that." If the information is simply extra detail, then "which" is usually the better choice. Correct usage of "that" and "which" enhances readability and allows readers to quickly grasp the intended meaning. This skill is invaluable for all forms of writing, from academic papers to casual blog posts. In essence, mastering "that" and "which" is a cornerstone of clear and effective communication.

Comprehensive Overview

At their core, "that" and "which" are relative pronouns that introduce relative clauses. These clauses add extra information to a noun in the main clause. Relative clauses can either be restrictive (also called essential) or nonrestrictive (also called non-essential). Understanding the difference between these two types of clauses is fundamental to using "that" and "which" correctly.

• Restrictive Clauses (Essential Clauses): These clauses provide information that is essential to identifying the noun they modify. They limit or define the noun, specifying which one is being referred to. A restrictive clause is crucial to the meaning of the sentence and cannot be removed without changing its core meaning. Restrictive clauses are introduced by "that" (though "that" can sometimes be omitted, especially in informal writing). They are not set off by commas.
• Nonrestrictive Clauses (Non-Essential Clauses): These clauses add extra information about the noun, but the information is not essential for identifying the noun. The noun is already clearly identified, and the clause simply provides additional detail. A nonrestrictive clause can be removed without changing the core meaning of the sentence. Nonrestrictive clauses are introduced by "which" and are always set off by commas.

The distinction between these two types of clauses affects the sentence's overall meaning and clarity. Using "that" when "which" is appropriate (or vice versa) can confuse the reader or even change the intended meaning of the sentence. This is why mastering the correct usage is so crucial for effective writing.

Historical Context

The preference for "that" in restrictive clauses and "which" in nonrestrictive clauses is a relatively modern development in English grammar. Traditional grammar rules were less strict, and "which" was often used in both types of clauses. However, over time, a clearer distinction emerged, driven by the desire for greater clarity and precision in writing.

The move towards differentiating "that" and "which" gained momentum in the 20th century, with influential style guides advocating for the stricter usage. Writers like H.W. Fowler, in his book A Dictionary of Modern English Usage, played a significant role in popularizing the distinction. While some writers still occasionally use "which" in restrictive clauses (especially in British English), the general trend is towards adhering to the "that" for restrictive and "which" for nonrestrictive" rule, particularly in American English. Understanding this historical context helps appreciate why the distinction, although seemingly subtle, is valued in modern writing.

Examples to Illustrate

Let's consider several examples to solidify the concept of restrictive and nonrestrictive clauses:

• Restrictive Clause (using "that"):
  • "The book that I borrowed from the library is due next week."
    • In this sentence, the clause "that I borrowed from the library" is essential. It tells us which book is being referred to. If we remove it, we no longer know which book is due.
• Nonrestrictive Clause (using "which"):
  • "The book, which is a first edition, is very valuable."
    • Here, the clause "which is a first edition" adds extra information about the book, but it's not essential. We already know which book is being referred to. The fact that it's a first edition is simply an additional detail.

Notice the commas in the second example. They are crucial for setting off the nonrestrictive clause introduced by "which." The absence of commas in the first example indicates the essential nature of the restrictive clause introduced by "that." These examples highlight how the choice between "that" and "which," along with the presence or absence of commas, significantly impacts the meaning of the sentence.

Common Mistakes

One common mistake is using "which" without commas in a restrictive clause. This often happens because writers are unsure whether the information is essential or not. Remember, if the information is crucial for identifying the noun, use "that" without commas.

Another mistake is using "that" when "which" is more appropriate. This usually occurs when writers are unaware of the distinction between restrictive and nonrestrictive clauses. If the information is simply extra detail and can be removed without changing the sentence's core meaning, use "which" with commas.

Pay attention to how sentences sound when you remove the clause in question. If the sentence still makes sense and retains its core meaning, the clause is likely nonrestrictive and should be introduced by "which" and set off by commas. If the sentence becomes unclear or loses its core meaning, the clause is likely restrictive and should be introduced by "that" without commas.

Trends and Latest Developments

While the distinction between "that" and "which" remains a standard grammatical rule, there's an ongoing debate about its strict adherence. Some style guides, particularly those geared towards more informal writing, are becoming more lenient, allowing for the occasional use of "which" in restrictive clauses, especially when it improves sentence flow. However, this flexibility is generally discouraged in formal writing.

In the digital age, where writing styles are often more conversational and less formal, it's not uncommon to see "which" used in place of "that," particularly in online articles and blog posts. This trend reflects a broader shift towards more relaxed grammar rules in online communication. However, it's crucial to be aware of your audience and the context in which you're writing. If you're writing for a formal publication or a professional audience, it's still best to adhere to the traditional rules regarding "that" and "which."

Ultimately, the goal of writing is to communicate effectively. If using "which" in a restrictive clause makes your sentence sound more natural and doesn't compromise clarity, you might choose to do so in informal writing. However, it's essential to be mindful of the potential for confusion and to prioritize clarity above all else. The trend towards leniency doesn't negate the value of understanding the underlying grammatical principles.

Tips and Expert Advice

Here are some practical tips and expert advice to help you master the usage of "that" and "which":

• Identify the Clause Type: The first step is always to determine whether the clause you're adding is restrictive (essential) or nonrestrictive (non-essential). Ask yourself: Is this information crucial for identifying the noun? If the answer is yes, it's a restrictive clause, and you should use "that" without commas. If the answer is no, it's a nonrestrictive clause, and you should use "which" with commas.

• Read the Sentence Aloud: Sometimes, reading the sentence aloud can help you determine whether a clause is essential or not. When you read a nonrestrictive clause, you'll naturally pause slightly before and after it, which corresponds to the commas. With a restrictive clause, there's no pause because the information is integrated into the sentence's core meaning.

• Try Removing the Clause: Another helpful technique is to try removing the clause from the sentence. If the sentence still makes sense and retains its core meaning, the clause is likely nonrestrictive. If the sentence becomes unclear or loses its core meaning, the clause is likely restrictive.

• Pay Attention to Commas: The presence or absence of commas is a key indicator of whether you should use "that" or "which." Remember, "that" is never preceded by a comma, while "which" is always preceded by a comma (and usually followed by one as well, unless it's at the end of the sentence). The use of commas is often more important than the choice between "that" and "which," as incorrect comma usage can significantly alter the meaning of a sentence.

• Practice with Examples: The best way to master the usage of "that" and "which" is to practice with examples. Write your own sentences using both words in different contexts. Analyze sentences from books, articles, and other sources to see how professional writers use "that" and "which." The more you practice, the more intuitive it will become.

• Consult a Style Guide: If you're still unsure, consult a reputable style guide, such as The Chicago Manual of Style or AP Stylebook. These guides provide comprehensive rules and examples for grammar and punctuation, including the usage of "that" and "which."

• Get Feedback: Ask a friend, colleague, or teacher to review your writing and provide feedback on your usage of "that" and "which." A fresh pair of eyes can often catch mistakes that you might have missed. Constructive criticism is invaluable for improving your writing skills.

• Consider Your Audience and Context: As mentioned earlier, the level of formality in your writing should influence your adherence to the strict rules regarding "that" and "which." If you're writing for a formal audience, it's best to follow the traditional rules. If you're writing for a more informal audience, you might have more flexibility.

By following these tips and practicing regularly, you can develop a strong understanding of when to use "that" and "which" and improve the clarity and effectiveness of your writing.

FAQ

Here are some frequently asked questions about the usage of "that" and "which":

Q: Can I always use "which" instead of "that"? A: No, it's generally not advisable to always use "which" instead of "that," especially in formal writing. While some style guides are becoming more lenient, using "that" for restrictive clauses is still the preferred and grammatically correct option.

Q: What if the clause comes at the beginning of the sentence? A: When a relative clause comes at the beginning of a sentence, it's usually nonrestrictive and should be introduced by "which" and set off by commas. For example: "Which is a first edition, the book is very valuable."

Q: Is it ever okay to omit "that"? A: Yes, "that" can sometimes be omitted, especially in informal writing, when it introduces a restrictive clause that is followed by a subject and verb. For example, instead of "The book that I read was interesting," you can say "The book I read was interesting." However, omitting "that" can sometimes make the sentence less clear, so use your judgment.

Q: What's the difference between British and American English regarding "that" and "which"? A: In British English, the distinction between "that" and "which" is sometimes less strict than in American English. British writers may be more likely to use "which" in restrictive clauses. However, the trend in British English is also towards adhering to the "that" for restrictive and "which" for nonrestrictive rule, particularly in formal writing.

Q: How do I remember the rule? A: A helpful mnemonic is: "That" is restrictive, "which" is extra, and "which" needs a comma.
