'dishonestly-expressed' originates from the combination of 'dishonest' and 'expressed', where 'dishonest' comes from Old French 'deshoneste', meaning 'shameful' or 'disgraceful', and 'expressed' from Latin 'expressus', meaning 'clearly presented'.

'dishonest' changed from the Old French word 'deshoneste' and eventually became the modern English word 'dishonest'. 'Expressed' evolved from the Latin 'expressus' through Middle English.

Initially, 'dishonest' meant 'shameful' or 'disgraceful', but over time it evolved into its current meaning of 'not honest'. 'Expressed' has largely retained its meaning of 'clearly presented'.
