The word "instruction" derives from the Latin instructio, meaning "a building, arrangement, or teaching," which comes from instruere ("to build, prepare, teach"). The root struct (from Latin struere, "to build") is central to many English words (e.g., "construct," "structure"). Over time, "instruction" shifted from the literal sense of "building" to the metaphorical sense of "building knowledge" or "teaching." The suffix -ion nominalizes the verb, turning the action into a concept.
