1.3.4.1 Verbs
Because these verbs have no complements, their subcategorisation frames are empty (as indicated by the ‘null symbol’ Ø, which typically stands for the absence of content). These verbs obviously differ from those such as wait which have non-null subcategorisation frames. We might distinguish between the two types by referring to those in (72) as true intransitives and those such as wait as being prepositional verbs.
