sentences:  This is an example of a subject control construction, where the pronominal subject [He] is selected for by both the main verb [like] and the embedded infinitive verb [stay], thus forcing the introduction of an unpronounced lexical item (PRO) at the subject of the embedded clause, in order to fulfil the selectional requirements of both verbs.Alternatively, we see object control constructions when the object of the sentence controls the meaning of PRO.However, while the meaning of PRO can be determined by its controller (here, the subject of the matrix clause), it does not have to be.
