adjektiiviadverbialinen
Adjektiiviadverbiaalinen refers to a grammatical construction where an adjective functions in a manner similar to an adverb, modifying a verb or another adjective. This phenomenon occurs in several languages, including Finnish, where it can express a manner, state, or quality of the action or description. For example, in Finnish, an adjective in the nominative case can be used adverbially to describe how an action is performed. This usage often conveys a sense of the subject's state or disposition during the action.
The distinction between a true adjective and an adjective used adverbially can sometimes be subtle and context-dependent.
