(no subject)

* NYSEC has three core cases: absolutive, dative, and ergative. However, instead of using only one of these for the subject, NYSEC uses each case for a specific role. What's more, the verb ending changes according to which case is the "subject", selected according to a hierarchy: ergative > dative > absolutive. That is, if the verb "licenses" an ergative argument, the verb takes the endings for agreeing with the ergative case. Ditransitive verbs and action verbs typically fall into this class. If the verb can't take an ergative argument, but can take a dative one, the verb takes the endings for agreeing with the dative case. Verbs of perception typically fall into this class. Other verbs (intransitive) take the endings for agreeing with the absolutive case. All this is simplified of course. NYSEC is supposed to be a Euroclone, but this feature is decidedly un-European.

Another interesting feature is that perfective class verbs lack a simple present tense (they must use the present progressive or the present habitual) while imperfective class verbs lack the imperative mood.
