Relative clauses with 的

Mandarin puts the whole modifying clause BEFORE the noun and joins it with 的, the reverse of English which/that/who clauses: 我买的书 (the book I bought), 昨天来的人 (the person who came yesterday), 会说中文的朋友 (a friend who can speak Chinese). There is no relative pronoun - 的 does all the work - and the head noun can drop entirely (买的 = the one bought).
