The quality or state of being capable of being known, recognized, or perceived.
From cognisable (capable of being known) plus the suffix -ity (quality or state). Cognisable derives from Latin cognoscere (to know), and the word traveled through Old French into Middle English.
This abstract noun appears mostly in British philosophy and law, discussing what can theoretically be perceived or understood—it's the foundation of debates about consciousness and knowledge itself!
