Hi Experts,

I often get confused in which/that pronoun constructions. I am aware that "that " is to introduce a mandate while which makes things optional but I often get confused in pronoun references involving "which" and "that". Also is this true that which only refers to a noun just before the `,which` clause.

Please guide me to a good article/video which can help me resolve errors involving such pronouns.(Preferably complex sentences where pronoun reference determination can be a challenge)
