МОДАЛЬНЫЕ ГЛАГОЛЫ


 

  Модальность - это отношение автора к сообщаемой информации.
Каждый модальный глагол имеет свое единое значение, которое он может реализовать в двух ситуациях:

1 ситуация - побуждение к действию извне или изнутри;
2 ситуация - оценка вероятности события.

     Так, предложение He must come может иметь двоякое значение. В первой ситуации - Он должен (обязан) прийти. Во второй - Он, должно быть, (вероятно) придет. В первой ситуации глагол must означает требование, побуждение извне, во второй - оценку вероятности события.
