Relative clause добавляет информацию о существительном. В "I met a student who speaks three languages." часть "who speaks three languages" описывает student. Sentence structure guide.
Что такое relative clause
"who" относится к людям, "which" — к предметам, "whose" выражает принадлежность, "where" — место, "when" — время.

Defining и non-defining clauses
Defining clause содержит необходимую информацию без запятых: "The student who sits next to me is from Brazil." Non-defining clause даёт добавочную информацию, выделяется запятыми и не допускает "that".

Когда можно опустить местоимение
Объект можно опустить: "The book I bought is useful." Подлежащее опускать нельзя: "The student who called me is my classmate.". Pronoun guide.
Ошибки и практика
Не дублируйте местоимение: вместо "The book that I bought it is useful." нужно "The book that I bought is useful.". This also strengthens writing skills.
