'misinstruction' originates from the prefix 'mis-' meaning 'wrong' or 'incorrect' and the word 'instruction' from Latin 'instructio', where 'instruere' meant 'to build' or 'to teach'.

'instructio' transformed into the Old French word 'instruccion', and eventually became the modern English word 'instruction'. The prefix 'mis-' was added to form 'misinstruction'.

Initially, 'instruction' meant 'to build or teach', but with the prefix 'mis-', it evolved to mean 'incorrect teaching or guidance'.
