Etymology

Origin of instruction

First recorded in 1375–1425; late Middle English instruccio(u)n, from Latin instructiōn-, stem of instructiō; equivalent to instruct + -ion


Explanation

Instruction is vital for education, as it is the transfer of learning from one person to another. Any time you are given directions or told how to do something you are receiving instruction. The noun instruction is related to the word structure; both share the Latin root structus, "built." The use of the word as we know it today appeared in the early 15th century from the Old French. Today it refers to the action of teaching and the job of a teacher. It can also be used to denote the directions themselves. Consider the word's connection with structure: effective instruction is presented in an orderly, structured manner.
