What does modal mean?
Modal is an adjective and technical noun connected with modes, forms, and kinds of expression. Its best-known use is in grammar, where it describes modal verbs such as must, could, should, and might. These words express relationships of necessity, possibility, permission, obligation, and advice rather than simply making assertions about actions or states. The adjective is also used in modal logic, where propositions can be described as necessary or possible, and in modal music, which is organized around particular musical scales.
