relative pronoun - who vs whom

Use 'who' to refer to a subject of a sentence.

Use 'whom' to refer to a an object of a sentence.

If you are still confused - Use the he/him method to decide which word is correct.

E.g - Who/Whom started this thread ? - He, so use 'who'

By who/whom was this thread started - Him, so use 'whom'

Hope this helps !!

I wanted to know the usage of who/whom as 'relative pronoun'

The examples may be interrogative but the same rule applies when 'who/whom' act as relative pronoun in both restrictive and non restrictive clauses.
