In Catalan Sign Language (LSC), verb agreement [MORPHOLOGY 3.1] is crucial to determine the argument structure of predicates, as it only involves syntactic arguments, and not adjuncts. In the following subsections, two different types of manual and non-manual verbal agreement inflections are described: person agreement (with animate participants) and locative or spatial agreement (with arguments of location and movement predicates encoding goal, source, path or location). Moreover, the realization of argument structure in some plain verbs that in LSC can show agreement with their arguments is described.
