#mental grasp

• Apprehend — A neologistic term borrowed from French or Latin; to perceive, understand, or grasp a truth, concept, or phenomenon through the intellect or intuition, going beyond superficial observation. In psychology and philosophy, it describes the conscious act of immediate mental grasping of a reality, while in an international legal (bookish) context, it can also mean to arrest or detain a person.
• Apprehension — The act of apprehending and its result; a cognitive process of perceiving, grasping, or conceptually understanding a reality, idea, or theory through the intellect or intuition. In experimental psychology, it describes the immediate mental seizing of a stimulus, whereas in international legal jargon, it refers to the detention or arrest of a suspect.
• Apprehension (archaic) — A bookish, longer, or archaic variant of the noun 'aprehensie' (fear / unease); also, in old international law or ancient legal treatises, it denotes the physical or administrative action of capturing, arresting, taking possession of, or seizing an asset or a suspect. In classical philosophy, it represents the intellect's faculty of structurally grasping an idea.
