не понятно, что значит составить одно слово из другого. возможно, вы имели в виду "подобрать однокоренные или родственные слова"? если так, ответ находим в любом словаре, но помним, что слово  possessive (имеющий, владеющий) само образовано от  possess (владеть, обладать), производными являются слова  possession (владение, обладание) и   possessor (владелец, обладатель).
