@tanguatlay,
1. Where is John, who was waiting for me?
2. Where is John who was waiting for me?
Quote:I think it should be #1 because who was waiting for me is a non-defining clause.
Could I know whether I am correct in my explanation?
Situation #1 - Ms Tan knows one John and I [jtt] know that to be fact.
1. Where is John, who was waiting for me?
This is a non-defining clause.
Situation #2 - Ms Tan knows two fellows by the name of John and I [jtt] know that to be fact, that she knows two fellows named John.
What I don't know at this point in 2. "Where is John" is which John you are referring to.
With the addition of "
who was waiting for me", it becomes clear to me, because of some previous knowledge.
In this case, is the underlined a defining clause?
