'agrimony' originates from Latin, specifically the word 'agrimonia', where 'agri-' meant 'field' and '-monia' was a suffix used in plant names.

'agrimonia' transformed into the Old French word 'agrimoine', and eventually became the modern English word 'agrimony'.

Initially, it referred to a specific plant used in medicine, and this meaning has largely remained the same in modern usage.
