2 what kind of usage

1. Replace the above things or situations (singular or plural) in the last unrestricted attributive clause.

2. Used as an interrogative pronoun in interrogative sentences and a connecting pronoun in noun clauses, indicating "where, where".

3. If the antecedent of an unrestricted attributive clause refers not to the content of the main clause, but to a specific person, time and place, then which one is not needed.

First, the relative pronouns that and which are the subject and object in the attributive clause, and they are placed between the antecedent and the attributive clause to play a connecting role. When things are mentioned, they are usually interchangeable.

That, you can't omit it when you are the subject in a clause. When used as an object, it is often omitted in spoken and informal questions.
