The topic “argument structure and morphology” refers to the interaction between the number and nature of the arguments taken by a given predicate on the one hand, and the morphological makeup of that predicate on the other. This domain turns out to be crucial to the study of a number of theoretical issues, including the nature of thematic representations, the proper treatment of irregularity (both morphophonological and morphosemantic), and the very place of morphology in the architecture of the grammar. A recurring question within all existing theoretical approaches is whether word formation should be conceived of as split across two “places” in the grammar, or as taking place in only one.

The Causative/Inchoative alternation involves pairs of verbs, one of which is causative and the other non-causative syntactically and semantically (e.g., John broke the window vs. The window broke). In its causative use, an alternating verb is used transitively and understood as externally caused. When used non-causatively, the verb is intransitive and interpreted as spontaneous. The alternation typically exhibits an affected argument (i.e., a Theme) in both intransitive and transitive uses, whereas the transitive use also involves a Causer that brings about the event. Although they are often volitional agents (e.g., John broke the window with a stone), external causers may also be non-volitional causers (e.g., The earthquake broke the windows) and instruments (e.g., The hammer broke the window). Morphologically, languages exhibit different patterns reflecting the alternation, even intralinguistically. In languages like English, alternations are not morphologically coded, but they are in most languages. Languages like Hindi commonly mark causative (or transitive) alternations by means of different mechanisms, such as internal vowel changes or causative morphology. In many European languages, a subset of alternating verbs may exhibit an uncoded alternation, but most alternating verbs mark anticausativization with a reflexive-like clitic. In Yaqui (Uto-Aztecan), different patterns are associated with different verbal roots. The alternation may be uncoded, equipollent (i.e., both alternating forms are coded), and anticausative. Theoretically, different approaches have explored the alternation. Both lexical and syntactic causativization and anticausativization accounts have been proposed to explain the alternation. A third approach postulates that both forms are derived from a common source.
The Romance languages are characterized by the existence of pronominal clitics. Third person pronominal clitics are often, but not always, homophonous with the definite determiner series in the same language. Both pronominal and determiner clitics emerge early in child acquisition, but their path of development varies depending on clitic type and language. While determiner clitic acquisition is quite homogeneous across Romance, there is wide cross-linguistic variation for pronominal clitics (accusative vs. partitive vs. dative, first/second person vs. third person); the observed differences in acquisition correlate with syntactic differences between the pronouns. Acquisition of pronominal clitics is also affected if a language has both null objects and object clitics, as in European Portuguese. The interpretation of Romance pronominal clitics is generally target-like in child grammar, with absence of Pronoun Interpretation problems like those found in languages with strong pronouns. Studies on developmental language impairment show that, as in typical development, clitic production is subject to cross-linguistic variation. The divergent performance between determiners and pronominals in this population points to the syntactic (as opposed to phonological) nature of the deficit.
