== Ergative - again == 

 Agreeing with the previous post about the supposedly ”ergative” suffix: the fact that there is a verbal suffix referring to the object  is simply an agreement between the verb and the object (see Agreement (linguistics)), also found for example in Hungarian, which, however, does not display any ergative features, it’s an agglutinative language with nominative-accusative alignment, since its subject is in the nominative and it's object is in the accusative. 
 Ergative means the subject of a transitive verb receives the ergative case, whereas the subject of an intransitive verb and the object of a transitive verb receive the absolutive case (for details see Ergative–absolutive language), and this has nothing to do with verb-oject agreement.
