2.1. The syntactic realization of argument structure
In order to express a complete predication that refers to an event or a situation, verbs need to combine with certain number of constituents. When these constituents are obligatory in a predicate they are called arguments. The argument structure of a verb is determined by the number of obligatory constituents it must hold which in turn are determined by the semantics of the verb. Verbs that only require one argument (the external one, realized as subject) are called intransitive verbs. Verbs that require two obligatory arguments (the subject and the internal one, realized as direct object) are called transitive verbs. Lastly, verbs that require three obligatory arguments (the subject, the direct object and a second internal argument, the indirect object) are called ditransitive verbs. This chapter explores different types of argument structure in LSC and their realization in syntax.
