Модальными называются глаголы, выражающие не действие, а отношение к нему: возможность, необходимость, способность, вероятность и т. д. совершения действия, выраженного инфинитивом смыслового глагола, следующего за модальным.

Модальные глаголы всегда употребляются с инфинитивом смыслового глагола, образуя составное глагольное (модальное) сказуемое.

Эти глаголы называют еще недостаточными, так как у них отсутствует ряд грамматических форм, присущих другим глаголам:

1. Они не изменяются по лицам и не имеют окончания –s в 3-м лице ед. числа (кроме эквивалентов модальных глаголов).

2. У них нет неличных форм инфинитива, причастия и герундия, а потому не имеют сложных видовременных форм (будущего времени, длительных и перфектных форм).

3. За исключением глаголов can (could) и may (might) модальные глаголы имеют только одну форму настоящего времени.

Они имеют следующие особенности:

1. Инфинитив смыслового глагола, следующий за модальным глаголом употребляется без частицы to. Но модальный глагол ought, глаголы to have и to be в роли модальных, а также эквиваленты to be able и to be allowed требуют после себя инфинитива с частицей to. Эти глаголы далее сопровождаются круглыми скобками с частицей to внутри (to).

2. В вопросительном и отрицательном предложениях они употребляются без вспомогательного глагола (кроме глагола to have). В вопросительном предложении модальный глагол (точно также, как и первый вспомогательный) ставится перед подлежащим.

3. Отрицательная форма образуется при помощи частицы not, которая ставится после модального глагола.


В группу модальных глаголов входят:

Модальные глаголы могут употребляться со всеми формами инфинитива, при этом:

1) Если действие относится к настоящему или будущему времени, то употребляется простой инфинитив (Indefinite) или длительный (Continuous):

He canplay tennis. Он умеет играть в теннис.
He maybe sleeping now. Он, возможно, спит сейчас.

2) Если действие относится к прошлому, то употребляется перфектный инфинитив:

Where could he have been? Где это он мог быть/(был)?
You couldhave taken care of her. Вы могли бы позаботиться о ней.
