'apprehensibility' originates ultimately from Latin, specifically from the verb 'apprehendere' (to seize, grasp), via Medieval Latin and English formations such as 'apprehensible' + the noun-forming suffix '-ity'.

'apprehensibility' developed from Latin 'apprehendere' -> Medieval Latin 'apprehendere/apprehensio' -> Middle English 'apprehenden/apprehension' -> adjective 'apprehensible' -> noun 'apprehensibility' in later English formations.

Initially related to the physical idea 'to seize or grasp' (from Latin), the sense shifted toward mental grasping; the modern meaning focuses on 'capability of being understood' rather than physical seizure.
