'wither' originates from Old English, specifically the word 'wītherian,' where 'wīther' meant 'against' or 'contrary.'

'wītherian' transformed into the Middle English word 'witheren,' and eventually became the modern English word 'wither.'

Initially, it meant 'to go against or oppose,' but over time it evolved into its current meaning of 'to dry up or lose vitality.'
