Re: Disambiguation of argument reference

     I'm not sure I understand everything you said here...   I think I
understood some, though, so I can try to help.

     First, to answer a question, prepositional arguments for mandatorily
ditransitive verbs *are* core case arguments.   So, if you were to listen the
arguments of "to put", it'd be something like x (placer), y (placed object),
and z (place).   Oblique arguments can be dropped in English, and their
prepositions *can remain* in question form: "I'm going (to the store)", and
"Where are you going to?"   "I'm sitting (on the bench)", and "What are you
sitting on?"   (The parenthetical phrases are optional.)   However, you can't
say, *"I put the book (on the table)", or *"What are you putting on?"--if you
said the latter, it could only refer to clothing (or music).   So they are
core arguments, even though it can vary (e.g., "on x", "over there", "right
here", etc.).

     And for your argument question...   If I understand it, you're talking
about nominalizing transitive verbs, so that the resulting noun can still
have an object?   If this is the case, this is what I do in my language
Zhyler:

/say-um/ = "I die", or "I'm dying" ("die" + 1sg.)

/petti-r say-as-um/ = "I kill the king", or, lit., "I cause the king to die"
("king" + ACC., "die" + CAUS. + 1sg.)

/sixa-r petti-r-ez say-as-as-um/ = "I hire a hitman to kill the king", or "I
cause him to cause the king to die"   ("man" + ACC., "king" + ACC. + ACC.,
"die" + CAUS. + CAUS. + 1sg.)

So in that last sentnece, "king" becomes a double object, and gets two
accusative tags in a row!   (The different forms of the accusative are due to
phonological rules.)   The hitman, then, gets one accusative, because he's
only a patient of one idea, I guess you'd say.   My accusative tag
(unbeknownst to me) is actually designed to build, since /r/ > [z] / [r]V_ .
 I had no idea that this would end up happening, but it looks cool!   ~:D
It's kind of like how the causative in Turkish can show up as /-dIr/ or /-t/,
depending on how many syllables there are, so you can just build and build.
So, is that info relevant, or was I reading what you wrote wrong?
