Meanings of modal verbs

The meanings of modal verbs are a little difficult to single out and define clearly (especially if we try to define them in Russian). For example, when speaking about the main meaning of the verb CAN, some linguists use the words "ability, possibility", others speak about "physical and mental ability", still others say "ability, power, skill, opportunity". The material Overview of Modal Verbs describes the meanings of modal verbs in general, and typical examples of use are given. The materials on specific modal verbs describe their meanings, usage, and peculiarities in detail. Specific modal verbs are grouped by their meaning in the materials of this section, e.g., Ability, Advice, Necessity.
