I currently have some unwanted ambiguity in my Russian grammar, I thought I’d document it here. This way I not only have structured notes for any future writing but also might get input from people.
Free word order and ditransitives is currently modeled using pairs like head-subj/subj head, head-comp/comp-head, etc. Ditransitives are modeled using an analogous head-2nd-complement rules.
I have currently the following sort of overgeneration, this is for sentence (1):
(1) Ivan dal Mashe knigu Ivan.NOM gave Masha.DAT book.ACC `Ivan gave Masha a book.' [rus]
But it doesn’t look like I could constrain the head-2nd-comp rules to be SUBJ < [ ] >, because then I will lose what’s currently my only way of licensing (2):
(1) Mashe Ivan dal knigu Masha.DAT Ivan.NOM gave book.ACC `Ivan gave a book to Masha.' [rus]
Any ideas on how to deal with the ambiguity while still keeping the coverage? Or do people think that orders which are potentially somewhat marked should rightfully be excluded? Except, even if I model information structure, in which case such orders should probably be included, I will still have this problem.
