'randomly-changed' originates from the combination of 'randomly' and 'changed', where 'randomly' is derived from 'random', meaning 'lacking a definite plan or order', and 'changed' is the past participle of 'change', meaning 'to make or become different'.

'randomly' evolved from the Middle English 'randoun', and 'changed' from the Old French 'changier', eventually forming the modern English term 'randomly-changed'.

Initially, 'randomly' meant 'with great speed or force', but over time it evolved to mean 'without a specific pattern', while 'changed' has largely retained its meaning of 'to make different'.
