Почему в английском так мало слов, означающих спонтанные эмоции? Ну "вау".ну "ауч"...А ещё что?

Таких слов полным-полно, еще и всякие сленговые добавляются постоянно, подростковые словечки. Язык точно также развивается, как и любой другой. Просто в наших школах и институтах этому не учат. Не выходят на такой продвинутый уровень
