Understanding the Basics

Definition of ‘That’

In English grammar, ‘that’ is a relative pronoun used to introduce a restrictive clause. It is used to refer to a specific thing or person and is often used to provide essential information about the noun it modifies. ‘That’ is used when the information that follows is necessary to identify the noun being referred to. For example, “The book that I read last night was really interesting.” In this sentence, ‘that’ is used to introduce the restrictive clause “that I read last night,” which provides essential information about the book being referred to.

Definition of ‘Which’

‘Which’ is also a relative pronoun used to introduce a clause, but it is used to provide non-essential information. It is used to add extra information about the noun it modifies. ‘Which’ is used when the information that follows is not necessary to identify the noun being referred to. For example, “The book, which was written by my favorite author, was really interesting.” In this sentence, ‘which’ introduces the non-restrictive clause “which was written by my favorite author,” which adds extra information about the book being referred to.

When deciding whether to use ‘that’ or ‘which,’ it is important to consider the type of information being provided. If the information is necessary to identify the noun being referred to, use ‘that.’ If the information is extra or non-essential, use ‘which.’

It is important to note that the use of ‘that’ and ‘which’ can affect the meaning of a sentence. Using ‘that’ can indicate a more specific or limited meaning, while using ‘which’ can indicate a more general or broader meaning. Therefore, it is important to choose the correct word to convey the intended meaning accurately.

Usage of ‘That’ and ‘Which’

When it comes to using ‘that’ and ‘which’ in a sentence, it’s important to understand the difference between restrictive and non-restrictive clauses. In formal American English, ‘that’ is used in restrictive clauses, while ‘which’ is used in non-restrictive clauses.

Restrictive Clauses

A restrictive clause provides essential information to the meaning of a sentence. It is a clause that cannot be removed from the context of the sentence without changing the meaning of the sentence. In such cases, ‘that’ is used to introduce a restrictive clause.

For example, “The car that I bought yesterday is red.” In this sentence, the restrictive clause “that I bought yesterday” is essential to the meaning of the sentence. Without this clause, the sentence would not make sense.

Non-Restrictive Clauses

A non-restrictive clause provides additional information to the meaning of a sentence. It is a clause that can be removed from the context of the sentence without changing the meaning of the sentence. In such cases, ‘which’ is used to introduce a non-restrictive clause.

For example, “My car, which is red, is parked outside.” In this sentence, the non-restrictive clause “which is red” provides additional information about the car. The sentence would still make sense without this clause.

It’s important to note that non-restrictive clauses are often set off by commas, while restrictive clauses are not. This is because non-restrictive clauses are not essential to the meaning of the sentence and can be removed without changing the sentence’s meaning.

Examples in Context

Examples of ‘That’

When using ‘that’, it is important to keep in mind that it is used in restrictive clauses. This means that the clause is essential to the meaning of the sentence and cannot be removed without changing the sentence’s meaning. Here are some examples of ‘that’ in context:

The book that I borrowed from the library is due tomorrow.
The car that is parked outside belongs to my neighbor.
The movie that we watched last night was really good.

As you can see in these examples, ‘that’ is used to introduce a clause that is essential to the meaning of the sentence. Without the clause, the sentence would not make sense or would convey a different meaning.

Examples of ‘Which’

On the other hand, ‘which’ is used in nonrestrictive clauses. These clauses provide additional information about the subject of the sentence but are not essential to the sentence’s meaning. Here are some examples of ‘which’ in context:

My new phone, which I bought last week, is already outdated.
The painting, which was created by a famous artist, sold for millions of dollars.
The cake, which was made from scratch, tasted delicious.

As you can see in these examples, ‘which’ is used to introduce a clause that provides additional information about the subject of the sentence. The clause can be removed without changing the sentence’s essential meaning.

It is important to note that using ‘which’ in a restrictive clause is grammatically incorrect. In such cases, ‘that’ should be used instead.

Common Mistakes and How to Avoid Them

Ambiguity

One of the most common mistakes people make when using “that” and “which” is creating ambiguous sentences. In such cases, it is unclear which noun the clause is modifying. This can lead to confusion and misinterpretation of the intended meaning. Therefore, it is essential to use “that” and “which” correctly to avoid ambiguity.

Here are some examples of ambiguous sentences:

The book, which is red, is mine.
The book that is red is mine.

In the first sentence, it is unclear which book is being referred to as “mine.” Is it the red book or another book? In the second sentence, it is clear that the book being referred to as “mine” is the red book.

To avoid ambiguity, use “that” for essential clauses, which are necessary to the meaning of the sentence, and “which” for non-essential clauses, which provide additional information but are not necessary to the meaning of the sentence.

Misplacement

Another common mistake people make when using “that” and “which” is misplacing the clauses. This can also lead to confusion and misinterpretation of the intended meaning. Therefore, it is essential to place the clauses correctly to avoid misplacement.

Here are some examples of misplaced clauses:

The car that I bought, which is red, is in the garage.
The car, which is red, that I bought is in the garage.

In the first sentence, it is unclear which car is being referred to as “red.” Is it the car that was bought or another car? In the second sentence, it is clear that the car being referred to as “red” is the car that was bought.

To avoid misplacement, place the essential clause immediately after the noun it modifies. If the clause is non-essential, use commas to set it apart from the rest of the sentence.

By following these guidelines, you can avoid common mistakes when using “that” and “which” and ensure that your writing is clear, concise, and easy to understand.

Tips for Remembering the Difference

When it comes to using “that” and “which,” it can be challenging to remember the difference between the two. However, there are a few tips and tricks that can help you keep them straight and avoid making common mistakes.

Firstly, it’s essential to understand the difference between a restrictive and nonrestrictive clause. A restrictive clause is essential to the meaning of the sentence, while a nonrestrictive clause is not necessary.

To remember which one to use, here are a few tips:

Use “that” for restrictive clauses and “which” for nonrestrictive clauses.
If you can remove the clause without changing the meaning of the sentence, use “which.” If the clause is necessary, use “that.”
If the clause is surrounded by commas, use “which.” If it’s not, use “that.”
Think of “that” as a tool to help define the noun it follows, while “which” is used to provide additional information.

Here are a few examples to help illustrate the difference:

Restrictive clause: The book that I read last night was excellent.
Nonrestrictive clause: The book, which I read last night, was excellent.

It’s also important to note that in informal writing or speech, the distinction between “that” and “which” may not be as critical. However, in academic or professional writing, it’s essential to use the correct word to avoid confusion and maintain clarity.

Frequently Asked Questions

When should I use ‘that’ in a sentence?

You should use ‘that’ in a sentence when the clause it introduces is essential to the meaning of the sentence. Such clauses are called restrictive clauses. For example, in the sentence “The book that I borrowed from the library was very interesting,” the clause “that I borrowed from the library” is essential to the meaning of the sentence because it identifies which book the speaker is referring to.

How do I know when to use ‘which’ instead of ‘that’?

You should use ‘which’ in a sentence when the clause it introduces is non-essential to the meaning of the sentence. Such clauses are called non-restrictive clauses. For example, in the sentence “The book, which I borrowed from the library, was very interesting,” the clause “which I borrowed from the library” is non-essential to the meaning of the sentence because it provides additional, non-essential information about the book.

What is the difference between restrictive and non-restrictive clauses?

Restrictive clauses are essential to the meaning of the sentence and cannot be removed without changing the meaning of the sentence. Non-restrictive clauses, on the other hand, are not essential to the meaning of the sentence and can be removed without changing the meaning of the sentence.

Can ‘that’ and ‘which’ be replaced with each other in a sentence?

No, ‘that’ and ‘which’ cannot always be replaced with each other in a sentence. ‘That’ is used to introduce restrictive clauses, while ‘which’ is used to introduce non-restrictive clauses. Therefore, using the wrong word can change the meaning of the sentence.

How should I punctuate sentences with ‘that’ and ‘which’?

When ‘that’ is used to introduce a restrictive clause, no comma is needed. When ‘which’ is used to introduce a non-restrictive clause, a comma is needed. For example, “The book that I borrowed from the library was very interesting” and “The book, which I borrowed from the library, was very interesting.”

Is there a difference between ‘which’ and ‘what’ in a sentence?

Yes, there is a difference between ‘which’ and ‘what’ in a sentence. ‘Which’ is used to refer to a specific thing or things from a group that has already been identified. ‘What’ is used to ask for information about something that has not been identified. For example, “Which book did you borrow from the library?” vs. “What book did you read last night?”

You should use 'that' in a sentence when the clause it introduces is essential to the meaning of the sentence. Such clauses are called restrictive clauses. For example, in the sentence \"The book that I borrowed from the library was very interesting,\" the clause \"that I borrowed from the library\" is essential to the meaning of the sentence because it identifies which book the speaker is referring to.
