Morphology
prehension = apprehend (semi-transparent) = prehend + ion
The noun is formed from the Latin combining stem 'prehend' + '-ion'; because 'prehend' is not a standalone modern English word, learners get only partial clues (related verbs like 'apprehend'/'comprehend' offer some help).
Etymology
The word prehension comes from the Latin root prehend meaning 'to seize' or 'to grasp', and you can see the same idea in comprehend, which means to 'grasp' an idea, and in apprehend, which means to 'seize' someone. So, prehension is the act of taking hold or grasping something, whether with the hand or with the mind.
