'trustworthy' originates from Old English, specifically the word 'trēowðe,' where 'trēow' meant 'faith' and '-ðe' was a suffix indicating quality. 'Directed' comes from Latin, specifically the word 'dīrectus,' where 'dī-' meant 'apart' and 'regere' meant 'to guide.'

'trustworthy' changed from the Old English word 'trēowðe' and eventually became the modern English word 'trustworthy.' 'Directed' evolved from the Latin 'dīrectus' through Old French 'directer' and Middle English 'directen.'

Initially, 'trustworthy' meant 'worthy of trust or confidence,' and this meaning has largely remained the same in modern usage. 'Directed' initially meant 'to guide or manage,' which is consistent with its current meaning.
