"I want him to arrive as early as possible."
Translation:Io voglio che arrivi al più presto.
"ArrivI" is a third-person subjunctive form, used in a subordinate clause with volere. This may help: http://italian.about.com/od/verbs/a/italian-verbs-present-subjunctive-tense.htm
Could someone please explain this answer - how is "I want him to arrive as early as possible" = "Io voglio che arrivi al piu presto". I understand the "early as possible" but where does the Italian answer indicate "him". It seems to speak of 2nd person arriving, not third.
There is no pronoun to suggest the I.O. is "him". It could be any singular pronoun. Please explain.
