Decoding the Grammar Dilemma- When to Use ‘Which’ Before or After a Comma-

Understanding the correct usage of “which” before or after a comma can be challenging for many English learners. The placement of “which” in a sentence depends on its role and the context in which it is used. This article aims to clarify the rules and provide examples to help you master the use of “which” in your writing.

In the English language, “which” is a relative pronoun that introduces a non-restrictive relative clause. This means that the clause provides additional information about the noun it modifies but is not essential to the meaning of the sentence. When “which” is used in a non-restrictive clause, it is typically followed by a comma.

For example, consider the following sentence:

“The book which you borrowed from the library is on the table.”

In this sentence, “which” introduces a non-restrictive clause that provides additional information about the book. The clause “which you borrowed from the library” is set off by commas, making it clear that it is non-essential information.

However, there are cases where “which” can be placed before a comma, especially when it is used to introduce a restrictive relative clause. A restrictive clause is essential to the meaning of the sentence and cannot be omitted without changing the meaning. In such cases, “which” is placed before the comma.

For instance:

“The book, which is on the table, is the one you borrowed from the library.”

In this example, “which” is used to introduce a restrictive clause that specifies which book is being referred to. The comma is placed after “which” to indicate that the clause is essential to the sentence.

It is important to note that the placement of “which” before or after a comma can also depend on the presence of other punctuation marks, such as semicolons or colons. In some cases, a semicolon or colon may be used to separate the main clause from the non-restrictive or restrictive relative clause, respectively.

For example:

“The book; which you borrowed from the library, is on the table.”

In this sentence, the semicolon is used to separate the main clause from the non-restrictive clause, making it clear that “which” is placed after the comma.

By understanding the rules and practicing with examples, you can master the use of “which” before or after a comma in your writing. Remember that the placement of “which” depends on its role in the sentence and the context in which it is used. With practice, you will be able to use “which” correctly and effectively in your writing.
