Capable of being encompassed, understood, or attained; possible to grasp or reach.
From 'compass' (to encircle, grasp, or understand) + '-able' (suffix meaning capable of being). 'Compass' derives from Old French and ultimately Latin 'compassus' (encircled).
When philosophers call something 'compassable,' they're using a word that echoes the original meaning of 'compass'—a tool that draws circles to encompass a space. Metaphorically, they mean 'can be taken in by the mind.'
