Also Quirky Case, like dative subjects in Icelandic (I need to reacquaint myself with this, since it's been several years since I read the literature on it).zompist wrote: ↑Thu Feb 28, 2019 3:24 pmKind of, but it would be more accurate to say that semantic roles apply to deep structure, while case applies to surface structure.
There are all sorts of ways case and semantic role may be different:
* passive
* dative movement
* applicatives
* raising ("I want him to go")
* politeness (e.g. Spanish's personal infinitive, in form equivalent to the dative)
* other odd reversals of valence (Sp. me gusta María vs. Pt. eu gosto Maria)
* other arbitrary stuff (e.g. Russian acc > gen in negative sentences)
* whatever is going on in English "him and I"
* case attraction
(Also, FWIW, the original idea of semantic roles was that they were universal. That's speculative, but if you accept it, individual languages may have other odd case divergences.)
One distinction that's commonly made in the generative literature is between "Structural Case" and "Inherent Case". The idea is that Structural Case is assigned (mainly) based on syntax, while Inherent Case is assigned (mostly) based on semantics. Nominative, Accusative and Absolutive (at least) are Structural Cases; I can't think of any languages where these Cases are used for fewer than three semantic roles (which I'm taking to be theta-roles). A typical Minimalist analysis of a transitive verb in a Nom/Acc language is that Accusative Case is given within the Verb Phrase and Nominative Case is given to the argument that moves to the subject position in the Tense Phrase; this argument is typically the more agent-y one, which is argued to start out higher in the syntactic tree.
OTOH, things like the Instrumental, Inessive, Comitative, etc. are Inherent Cases: they're not assigned based on the argument being a syntactic subject or object, and they (generally) have only one possible theta-role. IMO Cases like Dative and Ergative are somewhere in between: they each have their own typical theta roles (goal or experiencer for Dat, agent or causer for Erg), but they are also relevant to the syntax. Moreover, Pre/postpositions and Adjectives can sometimes assign a specific Case, which could either be more toward Structural or more toward Inherent depending on the phenomenon. I think the Ancient Greek thing where a single preposition could take a Noun Phrase in the Genitive, Dative or Accusative, each with a different meaning, is more toward Inherent Case. Other languages have a specific Case that must occur on pre/postpositional complements, such as Accusative.
It gets wilder in languages where object Noun Phrases are marked with different Cases based on whether they are animate or definite; quite a few IE languages mark animate direct objects with the Dative (this seems to have been innovated independently a few times). If you squint you can sorta see a semantic reason for this (the goal/experiencer theta roles are more "animate-y" than the patient/theme theta roles), but this is pretty clearly more on the syntactic side of things.
