Of a transitive verb.
As complement of a transitive verb,—
(1) Noun: "I will not call you cowards."
(2) Adjective: "Manners make beauty superfluous and ugly;" "Their tempers, doubtless, are rendered pliant and malleable in the fiery furnace of domestic tribulation." In this last sentence, the object is made the subject by being passive, and the words italicized are still complements. Like all the complements in this list, they are adjuncts of the object, and, at the same time, complements of the predicate.
(3) Infinitive, or infinitive phrase: "That cry which made me look a thousand ways;" "I hear the echoes throng."
