On the many faces of incompleteness: Hide-and-seek with the Finnish partitive object.

In the interplay of aspect and quantity in the Finnish system of object-marking the opposition between the partitive object and the (morphologically heterogeneous) total object plays a central role. The received view holds that the partitive object indicates incompleteness of the event in one way or another: it is used if the event does not take place at all (negation); if the aspect is unbounded; or if the quantity of the object referent is open (unbounded). The total object is used in affirmative sentences that indicate bounded aspect together with a closed quantity affected in full. Recent grammars have crystallized the three conditions of the partitive into a hierarchy of decreasing strength: negation > aspect > quantity: negation triggers the partitive irrespective of both aspect and quantity, and unbounded aspect triggers it irrespective of quantity. The article elaborates the hierarchy and argues that the aspectual function of the partitive is in fact not monolithic but consists of three different sub functions. [ABSTRACT FROM AUTHOR]
