Относительные местоимения служат для связи придаточных предложений с главным. Они являются союзными словами, которые отличаются от союзов тем, что они не только связывают придаточное предложение с главным, но и являются членами придаточного предложения.
Для связи придаточных предложений подлежащих, сказуемых и дополнительных с главным употребляются местоимения who кто (whom кого), whose чей, what кто, какой, which который, какой, кто, что. Они являются, таким образом, теми же вопросительными местоимениями, но употребленными не для вопроса, а для связи предложений):
Who has done it is unknown. Кто это сделал, неизвестно.

Relative pronouns are used to associate subordinate clauses with the principal. They are allied words, which differ from alliances in that they not only associate the subordinate clause with the principal, but are also members of the subordinate clause.
For communication between the subordinate clauses of the subject, predicate and complementary with the main one, pronouns are used: who who (whom whom), whose whose, what who, what, which which, what, who, what.
