'unreduced' originates from the prefix 'un-' meaning 'not' and the verb 'reduce' from Latin 'reducere', where 're-' meant 'back' and 'ducere' meant 'to lead'.

'reduce' changed from the Latin word 'reducere' and eventually became the modern English word 'reduce'.

Initially, 'reduce' meant 'to bring back or lead back', but over time it evolved into its current meaning of 'to make smaller or less in amount'.
