Relative clauses places: where/which - UsingEnglish.com …
General tips to understand the structure: 1- Where cannot be used before a main verb, while which can. 2- Try to put the noun which is modified into the relative clause. If it takes in/on or at preposition in front of itself, you need a " WHERE" or " prep + which" as a relative adverb. Last edited: Aug 2, 2006.
