1) Does the non-restrictive clause that start with "which........" ALWAYS have to describe the word before the non-restrictive clause?
For example: The dog, which eat my home-work...... Here "which....", the non-restrictive clause, describe the dog [the last word before the "which"
can you have the "non-restrictive" clause describe some other word [e.g. - any noun but the word just before which?]
2) Does the non-restrictive clause that starts with "which......." ALWAYS have to describe a word or can it describe a "PHRASE/CLAUSE, etc, etc"?
For example: The "blue swimming short that i wore", which were older than 10 years finally.........
Can the verbal experts pls help me better understand the aforementioned concept.
gmataquaguy, really fantastic questions. they are really genuine.
My response to the questions:
The perception to the usage difference of APPOSITIVE and restrictive/non-restrictive clauses, is really subtle.
==> Appositive modifies SUBJECT OF THE CLAUSE, see here:
http://www.gmatclub.com/phpbb/viewtopic ... highlight=
to ratify the Equal Rights Amendment, begun almost two decades ago
, has been unsuccessful despite efforts by many important groups, including the National Organization for Women.
Appositive: "begun almost two decades a go" modifies "An attempt", which is a subject of the whole clause - " An attempt ...,..., has been unsuccessful despite efforts by many important groups,..."
Whereas, the clauses - restrictive (starts with "that") and non-restrictive (starts with "which") always modify the word just preceded. see here:
" ..... disturbances in patients, which may limit their potential to relieve severe pain" - which modifies the patients.
So answers to your 2 Questions goes like this:
1. YES, restrictive/non-restrictive caluses have to modify the adjacent noun.
2. Never, atleast i havent seen any non-restrictive/restrictive clause modifying phrase/caluse.
Infect in your sentence - "blue swimming short that i wore", which was older than 10 years finally........." -
"blue","swimming", "that i wore" and "which was older than.." all are modifying the noun - "short"
I hope i m clear enough.
