'baronage' originates from Old French, specifically the word 'baronage', where the root 'baron' ultimately comes from Late Latin 'baro' meaning 'man' or 'servant'.

'baronage' changed from Old French 'baronage' (and Old French 'baron') into Middle English 'baronage', and eventually became the modern English word 'baronage' via Middle English usage.

Initially related to 'baro' meaning 'man' or 'servant' and then to the individual title 'baron'; over time it evolved to denote either the rank/dignity of a baron or the collective body of barons.
