In Hungarian, the nominal objects (patient or theme) of monotransitive (1) and ditransitive (2) verbs are both marked with the accusative (-t suffix). Pronominal recipients are marked with their dative case form. This is the typical way of marking in Hungarian, however a small group of ditransitive verbs (e.g. meglep ‘to surprise somebody’, megajándékoz ‘to give a present’) assign instrumental case to the theme (direct object) and accusative to the recipient (3). (Due to the marginality of this construction, we did not take it into consideration when the parameter values were determined.) Monotransitive and ditransitive verbs are both agreed with the object (which can either be a patient or a theme). The agreement is governed by the definiteness of the object (cf. Kenesei et al. 1998: 197–198, Komlósy 1992: 345–346). If it is the R that takes the accusative, it only counts as definite if it is in the third person.
