In linguistics, modal particles are a type of grammatical particle used in a sentence to add extra meaning, particularly in spoken language.[1] Modal particles have various functions, including adding emotion or emphasis,[2] or to express how sentence content is grounded in common knowledge between the speaker and participants.[3]
Languages that use many modal particles in their spoken form include Dutch, Danish, German, Hungarian, Russian, Telugu, Nepali, Norwegian, Indonesian, Sinitic languages, and Japanese.[4] Modal particles are often context-dependent and difficult to translate.
