Late Middle English, borrowed from Latin inceptiō, from inceptus, perfect passive participle of incipiō (“I begin”). The layering sense derives from the 2010 science fiction film Inception, in which a team of people infiltrate someone’s subconscious mind, proceeding through several layers of dreams with the goal of causing someone to incept an idea.
