Etymology: "Perceiver" is a plain formation: the verb "perceive" with the agent suffix "-er," which means one who performs the action. "Perceive" itself came into English from Old French "percevoir," which traces back to Latin "percipere," meaning to seize or grasp thoroughly, built from "per" (through, completely) and "capere" (to take). So the verb began as a physical image of taking hold of something, and only later came to mean becoming aware of something through the senses or the mind. The suffix does the rest of the work. English inherited "-er" through Middle English from Old English "-ere," and that ending traces back much further to the Latin "-arius," which marked a person connected with or practicing a certain activity. Over the centuries English attached "-er" to countless verbs, so "perceiver" slots easily beside words like "believer" or "receiver," and its meaning follows directly from the verb it contains.
