The words "where" and "when" have several jobs in English. For example, sometimes they can
be question words; sometimes, they can be conjunctions in adverb clauses;
and other times, they can be relative pronouns in adjective clauses!
Of course, in adjective clauses, we use "where" for places and "when" for times. It sounds easy, right?
Actually, it gets a bit complicated. In some adjective clauses, you can only use "when"; in others,
you can use "when" or "that" or Φ (no pronoun). Sometimes, you can use "which" or "that" or Φ;
other times, you can't use any of them. How can you figure out which pronouns to use? Let's see...
1. If there is NO preposition that goes with the place or time in the adjective clause, you can use "where" or "when".
If there IS a preposition, you can NEVER use "where" or "when".
EXAMPLES: I know a place where you can catch really big fish.
I know a place
in where you can catch really big fish.
2. If there is a preposition that goes with the place or time, then the adjective clause follows the usual rules
for an 'object' adjective clause; remember, there are two kinds - regular, and formal. [See quiz 2.]
EXAMPLES: I know the year in which Mary was born.
I know the year which/that/Φ Mary was born in.
Try the questions below. Some of the answers will be 'tricky', but see if you can follow the explanations. Good luck!
