Thank you Bismarck and Stephen S for pointing out the Object Complement (or predicate) function of these words. A lot of confusion results ("these things get us confused"!) when we fail to distinguish between a word's part of speech (adjective, adverb, noun, etc.) and a word's functional role in the sentence (direct object, indirect object, complement, predicate, etc.), especially since any given word can usually play any number of roles or masquerade as any part of speech. Is 'run' a verb ("I ran"), a noun ("We need to do another run of that"), etc.? Then on top of that we have to figure out what functional role the words plays with respect to the other roles in the sentence ("predicate" "direct object" "modifier" etc.).
