Relative pronouns

Arabic relative pronouns agree with the noun: الذي (masculine), التي (feminine), الذين (people, plural), اللذان and اللتان (two). الذي and الذين are written with one lam.

They follow a definite noun only: الرجل الذي رأيته, but رجل رأيته (a man I saw), with no pronoun at all.

When the relative is the object, a pronoun on the verb often refers back to it: الكتاب الذي قرأته, the book that I read.
