Oxford English Dictionary (www.oed.com) lists “call for" as an intransitive phrasal verb, while other dictionaries such as Macmillan and Longman list it as a transitive phrasal verb. I see that “call for," as a whole, as a set phrase, functions as a transitive phrasal which takes an object. In what other sense could it be intransitive?
