Relative Clauses

Lots of people confused to differentiate between the usage of clauses. Now, i'll explain a little bit deeper about it . Enjoy =) 

                                                although it's bytes, it's helpful.. so, please love grammar. :)

Extra information clauses

Preposition  +   whom / which

You can use a preposition before whom (for people) and which (for things). So, you can say:

To whom / with whom  / about which / without which etc. :

·         Mr Lee, to whom I spoke at the meeting, is very interested in our proposal.

In informal English we often keep the preposition after the verb in the relative clause. When we do this, we normally use who ( not whom) for people:

·         This is my friend from Canada, who I was telling you about.

All of  / most of etc. + whom/which

Study these examples:

Mary has three brothers. All of them are married. ( 2 sentences )

Mary has three brothers, all of whom are married. ( 1 sentence )

In the same way you can say:

None of / neither of / any of / either of                               

Some of / many of / much of / (a) few of + whom ( people )

Both of / half of / each of / one of / two of etc.+ which ( things )

You can also say the cause of which / the name of which etc. :

·         The building was destroyed in a fire, the cause of which was never established.

Which ( not what )

Joe got the job.      This      surprised everybody.  ( 2 sentences )

Joe got the job,      which   surprised everybody.  ( 1 sentence )

In this example, which = ‘ the fact that he got the job’. You must use which ( not what ) in sentence like these:

·         Sarah couldn’t meet us, which was a pity. ( not was a pity ).
