What is modality meaning?

Modality refers to the degree of certainty or possibility conveyed by a statement, based on the speaker's perspective or viewpoint. Modality in language can be categorized into two broad categories: possibility and necessity. Modality is expressed through various forms such as modal verbs (can, could, will, would, shall, should, may, might, must), adverbs (possibly, certainly, definitely), and other grammatical constructions. Modality helps speakers to convey their attitudes towards the information they are communicating and allows them to express degrees of certainty or uncertainty, obligation or permission, ability or inability, and preference or intention. It plays a crucial role in communication and is necessary for effective expression of thought and meaning.
