Both “which” and “in which” function as relative pronouns in English grammar, but they have distinct uses:
“Which” offers more general information about a noun or pronoun. “In which” narrows down the focus to a specific place or time.
Meaning of which
“Which” has a few different meanings depending on how it’s used in a sentence. It can be used with singular or plural nouns. In non-essential clauses, it’s often followed by a comma. In formal writing, it’s generally preferred over “that” for non-essential clauses referring to things (not people or animals).
Here’s the most common uses:
1. Interrogative Pronoun (Asking a question):
Used in questions to ask about a specific choice out of a limited set of options.
Examples:
Which shirt do you like better, the red one or the blue one?
Which movie are we watching tonight?
Which countries are competing in the Olympics this year?
2. Determiner (Making a question):
Similar to the interrogative pronoun but used before a noun to introduce a question.
Example:
Which color paint should I use for the living room?
3. Relative Pronoun (Connecting clauses):
Introduces a non-essential clause (information that can be omitted without affecting the core meaning) that provides additional details about a previously mentioned noun or pronoun.
Examples:
The book which I borrowed from you is fantastic. (We already know it’s the borrowed book)
The house which has a red door is mine. (We know it’s the house being referred to)
Meaning of In Which
“In which” functions specifically as a relative pronoun in English grammar. It’s used to introduce a non-essential clause that specifies a place or time mentioned earlier in the sentence.
“In which” can be used with singular or plural nouns referring to places or times. It’s often followed by a comma to separate the dependent clause from the independent clause. While not strictly necessary, “in which” can sometimes add a touch of formality to your writing.
Here’s its meaning and usage:
Function:
Connects a dependent clause (the “in which” clause) to an independent clause.
Provides additional information about a place or time, but this information is not essential for understanding the main point of the sentence.
Key Points:
Focuses on Location or Time: Unlike “which” that offers general information, “in which” narrows down the focus to a specific place or point in time.
Non-Essential Clause: The information provided by the “in which” clause can often be removed without affecting the core meaning of the sentence.
Formal Tone: “In which” is generally considered more formal than simply using “where” when referring to a location or time.
Examples:
The city in which I grew up has a beautiful coastline. (Specifies the exact city)
The time in which this happened is important. (Focuses on the specific time)
The library in which I found this book has a large collection of rare manuscripts. (Identifies the specific library)

To summarize, “which” and “in which” are both used as relative pronouns to introduce subordinate clauses in English grammar. “Which” adds extra information about a noun or pronoun in the main clause, while “in which” specifically refers to a place or situation mentioned in the main clause. Knowing the distinctions between the two can aid in selecting the correct one for a sentence.
