modalitet

Modalitet is the term used in several languages for modality. It designates the quality of a proposition to express possibility, necessity, obligation, or other speaker attitudes. The concept spans linguistics, philosophy, medicine, and cognitive science.

In linguistics, modality is shown through verbs, inflections, or adverbs and expresses the speaker’s stance toward the proposition. Subtypes include epistemic (knowledge about truth), deontic (permission or obligation), and dynamic or ability-related modality.

In philosophy and logic, modal logic analyzes necessity and possibility with operators such as necessarily and possibly. The framework extends to normative (deontic), epistemic, and other domains.

In medicine and rehabilitation, modalities denote treatment methods, such as physical modalities (heat, cold, ultrasound, electrical therapy) or pharmacological approaches, used to influence symptoms or function.

In information and cognitive science, modalities refer to perception channels (visual, auditory, tactile) and to multimodal systems that combine several channels for data processing and communication.

Etymology: modalitet comes from modality, Latin modus via French modalité; the term appears in some languages as the direct equivalent of modality, retaining the spelling variant modalitet in academic usage.
