Короче, всё просто, когда говорящий задает вопрос о неизвестных ему лицах или объектах, он заменяет эти слова местоимениями who, whom, whose, what и which.
Вопросительные местоимения в английском языке применяются только в вопросах специального типа. Они ставятся в начале предложения перед глаголом.
Эти местоимения принадлежат к классу вопросительных слов, известных также, как wh-words, так как почти все они начинаются с букв wh.
