'achymous' originates from Greek, specifically the word 'achymos,' where 'a-' meant 'without' and 'chymos' meant 'juice or sap.'

'achymos' transformed into the Latin word 'achymus,' and eventually became the modern English word 'achymous.'

Initially, it meant 'without juice or sap,' and this meaning has largely remained the same in modern usage.
