Modal particle

In linguistics, modal particles are always uninflected words, and are a type of grammatical particle. They are used to indicate how the speaker thinks that the content of the sentence relates to the participants' common knowledge or to add emotion to the meaning of the sentence. Languages that use many modal particles in their spoken form include Dutch, Danish, German, Hungarian, Russian, Telugu, Nepali, Norwegian, Indonesian, Chinese and Japanese. The translation is often not straightforward and depends on the context.
