reference: part of something you say or write in which you mention a person or thing - Longman
How can I analyse the phrase in which?
I asked a similar question before - Here
However, this sentence is quite different from the previous one. In the previous case, in which was located right after a noun. So it was easy to find the subject of in which but it is located after a verb ("write") in this sentence. The only subject is part of something. If so, what's the meaning?
Here is my attempt. According to the previous answer,
- reference is part of something you say or write
- You mention a person or thing in the part of something.
I could understand these two sentences respectively but I'm struggling to find a relation between the two sentences. I think it's because of in which.
I mean,
- reference is part of something you say or write
- reference is a person or thing you mention.
These are more like acceptable to me.
