'agenize' originates from the English word 'agent,' specifically the suffix '-ize,' where 'agent' meant 'a substance that exerts some force or effect.'

'agent' transformed into the verb form 'agenize' by adding the suffix '-ize,' which is used to form verbs indicating a process or action.

Initially, it meant 'to apply an agent,' and this meaning has largely remained the same in modern usage.
