'augmentor' originates from Latin, specifically the verb 'augmentare', where 'augere' meant 'to increase' and the suffix '-or' marked an agent (one who performs the action).

'augmentor' changed from the Late Latin noun 'augmentator' (meaning 'one who increases') and passed through Old French/Middle English forms related to 'augmenter' before becoming the modern English noun 'augmentor'.

Initially, it meant 'one who increases or adds to something', and over time it has retained that basic sense while also being used for technical devices or modules that perform enhancement.
