Morphology

instruction = instruct (transparent) = instruct + ion

The noun 'instruction' is transparently derived from the verb 'instruct' with the suffix '-ion' indicating the process or result.

Etymology

Instruction shares the Latin parts in- 'into' and struere 'to build', so you can think of each instruction as a small building block or order. That's why in computing an instruction is a single command the computer follows to make a program work.
