A relative is someone who has a relationship with you. Relative pronouns show a relationship between clauses. They join dependent clauses to main clauses.
Look familiar? They are also interrogative and demonstrative pronouns. In order to tell the difference, you must analyze how they are being used.
Interrogative:Who is that man in the photograph? (Who = Juan – but we don't know his name. That's why it's interrogative.)
Relative:Juan is the man who works in the mall. (Juan = man working in the mall)
The relative pronouns show a relationship between two clauses. They act like conjunctions. In the above sentences, who replaces the noun in the first sentence and relates Juan and the man working in the mall.
Interrogative:Whom did you ask about the movie times? (Whom = Dave)
Relative:Where is the person whom you asked about tickets? (Whom = person you asked)
Demonstrative:That is the book I found. (That = the book Little Women)
Relative:I found the book that you lost. (book I found = book you lost)
Who, whom, and whose relate to people (or pets if you refer to them by name). Which is used with objects. That is preferably used only with objects, but you will see it used with people. Try to get in the habit of using who with people instead of that. It is more polite.
