In Finnish, the telicity is mandatorily marked on the object: the accusative is telic, and the partitive is used to express atelicity. More accurately, the accusative case is used of objects that are completely affected by the situation as presented by the speaker, whereas using partitive implies that the object is only partially affected in the situation or that the situation is framed so that the object continues to be affected outside it. The terms "telic" and "atelic" are not traditionally used in Finnish grammatical description; instead, it is customary to speak of "resultative" and "irresultative" sentences.
