'agenize' originates from the word 'agent,' specifically the word 'agere' in Latin, where 'agere' meant 'to do or act.'

'agere' transformed into the English word 'agent,' and eventually became the modern English word 'agenize' through the process of adding the suffix '-ize.'

Initially, it meant 'to act or do something,' but over time it evolved into its current meaning of 'to treat with an agent.'
