Distinguishing Between Which & In Which in English Grammar

Which vs In Which in English Grammar

Though “in which” is a variation of the word “which,” there is a difference between their usages. Therefore, we can say that “which” and “in which” are two words that are characterized by different usages in the English language. Both “which” and “in which” are relative pronouns. They are, however, at times also used as interrogative pronouns. Out of the two, the word “which” has a wider scope in which it can be used. However, the word “in which” can only be used in specific instances. We will see how different these two terms are in their usages and also get to know about each term in this article.

What does Which mean?

The word “which” is used as a relative pronoun as well as an interrogative pronoun. As a relative pronoun, “which” is used to give additional information about a word in the same sentence. For example, look at the following sentence: “I saw the same snake which I saw at my house a few days ago.” In this sentence, the word “which” is used as a relative pronoun in the sense that it related or identified the snake that was previously seen. The word “which” is also used in the question formation, such as, “Which is the tallest building in the world?” One thing to remember is that “which” is used to refer to objects, animals, plants, and other living beings. It is not used to refer to human beings. Observe the sentences, “Which of these flowers do you like?” and “Which is the coolest place in the world?” In the first sentence, “which” is used to refer to flowers and, in the second sentence, “which” is used to refer to a place. In the same way, “which” is also used as a relative pronoun to refer to things and places. As you can see, “which” can refer to anything as long as we are talking about objects and not people.

When it comes to “which,” what most people find confusing is that whether to use a comma before “which” or not. You may also have come across sentences that use commas before the word “which” and sentences that do not use commas before the word “which.” The comma comes depending on the importance of the information the “which” clause provides. As we all know, the word “which” is the first word of a clause that provides additional information. If the information is not essential, then there is a comma before the word “which” and at the end of the clause too. However, if the information is essential to the sentence and the sentence does not give the correct sense without it, then we do not have commas. “Snoopy, which is very mischievous, is a brave dog.” In the first sentence, the comma shows that the information the “which” clause provides is not essential. The dog’s bravery is not connected to its mischievousness. However, the second sentence with no comma before “which” shows that the information is essential. “The table cloth which is pure white stains quickly.”

What does In Which mean?

On the other hand, “in which” is used as a combination of the preposition “in” and the relative pronoun “which.” Look at the following sentence: “In the hospital there is an accident block where my friend was admitted.” The same sentence can be said differently using “in which” as, “In the hospital there is an accident block in which my friend was admitted.” Thus, “in which” is used as an easy way to introduce a relative clause after a noun that refers to a place.

Look at the following sentence: “It was a time when people used stones.” The same sentence can again be said differently using “in which” as, “It was a time in which people used stone.” Thus, “in which” is used as an easy way to introduce a relative clause after a noun that refers to time. “In which” can also be used as an interrogative pronoun. Look at the following example: “In which storey does he live?” As you can see, “in which” can also be used as an interrogative pronoun as long as we are speaking about a place or a time.
