Argument realization and argument referencing in Soranî Kurdish
Soranî Kurdish can reference up to two arguments morphologically, a subject agreement marker and an incorporated object pronoun. One of the argument referencing morphs is verb-bound and occurs in a fixed position in the verb template (after the stem), while the other is a mobile morph that can occur either verb-internally (in second or last position) or verb externally. Either the subject agreement marker or the object incorporated pronoun can be verb bound or mobile morphs, depending on the tense and presence of an NP complement. Previous literature has analyzed mobile morphs as (VP) endoclitics. We argue that this is not the case as verb-external mobile morphs occur at the end of the last word of the least oblique NP complement and cannot attach to the last word of VP-internal PPs. We provide an edge-feature based analysis of verb-external mobile morphs and show that the same realizational rules account for the exponents of mobile morph features whether they occur verb-internally or verb-externally. We furthermore suggest that the dissociation between paradigm class (verb-bound or mobile morph) and syntactic status (subject or object; agreement marker vs. incorporated pronoun) challenges views that treat morphological structure as isomorphic to syntactic structure.
