Subcategorization
Different verbs can relate different numbers of entities: transitive versus intransitive verbs.
Tightly related verb arguments are called complements but less tightly related ones are called adjuncts. Prototypical examples of adjuncts tell us time, place, or manner of the action or state described by the verb.
Verbs are classified according to the type of complements they permit. This called subcategorization. Subcategorizations allow to capture syntactic as well as semantic regularities.
