Tending to hide, conceal, or withdraw; characterized by a tendency to hide or keep secret.
From Latin 'abditivus', derived from 'abditus' (hidden), the past participle of 'abondere' (to hide away). The '-ive' suffix means 'tending to' or 'characterized by'.
This is one of those beautiful English words borrowed from Latin that sounds mysterious because it literally means 'hiding-prone'—it's the kind of word a 17th-century scholar would use to describe secretive behavior.
