QUANTITIES IN ADJECTIVE CLAUSES

Some relative pronouns (usually, but not always, which—for objects, whom—for people) can be used together with expressions of quantity to create a non-restrictive adjective clause.

e.g. CALIFORNIA HAS A LOT OF VISITORS EVERY YEAR. MOST OF THEM GO TO DISNEYLAND.
- EVERY YEAR, CALIFORNIA HAS A LOT OF VISITORS, “MOST OF WHICH” GO TO DISNEYLAND.

e.g. I HAVE TWO COUSINS. YOU MET BOTH OF THEM.
- I HAVE TWO COUSINS, “BOTH OF WHOM” YOU MET.

Other quantifying relative pronoun combinations include:

some of (which/whom), many of (which/whom), none of, two of, half of, neither of, each of, all of, several of, a few of, a number of etc.

e.g. I TEACH SYNTAX TO OVER 300 STUDENTS, A FEW OF WHICH ACTUALLY ENJOY IT.

e.g. THERE ARE TWO WAYS AVAILABLE, NEITHER OF WHICH I LIKE.

e.g. THE PACK CONSISTS OF TEN BOOKS, EACH OF WHICH OFFER DIFFERENT INFORMATION.
