Relating to or showing expectation; characterized by waiting for or anticipating something.
From expect plus the suffix -ative (having the quality of, tending toward). This is a rare formation, mostly appearing in older philosophical and theological texts from medieval times onward.
Medieval theologians loved 'expectative'—they used it to describe the hope of resurrection or salvation. It's almost entirely replaced by 'expectant' in modern English, making it an antique word that scholars still recognize.
