None of these clauses has a finite verb: the first four contain an infinitive (cook, act, leave, go) and in the last, the auxiliary having is a present participle, and the main verb left a past participle. We can be sure that none of these clause are finite because they can’t possibly be independent clause – none of them could stand alone in English (although Finnish, for example, does have non – finite independent clause). None that the implication works this way: if a clause is non – finite (that is, it contains no finite verb) then it must be an embedded clause in English. If a clause is finite (i.e. contains a finite verb) then it may be either a main or a subordinate clause – we can’t tell without using other criteria.
