#### Modality

This is the way in which we express our attitude to what we are saying. We often associate modality with verbs (obligation, possibility, ability, necessity etc) but modality can also be expressed through adjectives, adverbs and nouns. This latter is called lexical modality.

Example

In the sentence He may come tomorrow we see modality expressed in the modal verb may. We can use lexical modality to express this too e.g. Perhaps he will come tomorrow (modal adverb), there’s a chance he will come tomorrow (modal noun), it’s possible he’ll come tomorrow (modal adjective).
