I'm reading a book about investing, and I came across a nonrestrictive relative clause in which there's a word whose function I can't seem to understand.
The author describes one of the duties of the analyst:
- the determination of definite price discrepancies existing between related securities, which situations may justify making exchanges or initiating hedging or arbitrage operations.
The word situations is my problem. It comes after which and before may, and it clearly relates to price discrepancies as a description of them as situations.
But what is its grammatical function? I know that it's a noun, so how comes there's a "new" subject in this clause, especially when we have the relative pronoun which?
I have the same misunderstanding in the following:
We had fish and chips, which food I always enjoy.
The word food relates of course to fish and chips, but I'm confused about the grammatical function of food.
