* "Which clauses" are relative clauses that refer to things (inanimate objects or abstract concepts). They typically start with the relative pronoun "which" and provide additional information about the noun they modify.
* "Who clauses" are relative clauses that refer to people. They typically start with the relative pronoun "who" and provide additional information about the person they modify.
Here's a simple way to remember:
* "Which" for things
* "Who" for people
Examples:
* "Which clause": "The book which I read last night was really interesting." ("Which" refers to "book," a thing)
* "Who clause": "The woman who lives next door is a doctor." ("Who" refers to "woman," a person)
Important Note: Sometimes you might see "that" used instead of "which" or "who." While "that" can be used in both cases, it's often considered more formal to use "which" and "who" when possible.
Let's summarize:
* "Which clauses" modify nouns referring to things (inanimate objects or abstract concepts).
* "Who clauses" modify nouns referring to people.
