(domain)
territory or field
Etymology
'domain' originates from Old French 'domaine', ultimately from Latin 'dominium', where 'dominus' meant 'lord' or 'master'.
'dominium' in Latin became Old French 'domaine', was borrowed into Middle English as 'domaine'/'domain', and evolved into the modern English 'domain'.
Initially it referred to 'ownership' or 'property' (land belonging to a lord); over time it broadened to mean any area of control or a field of activity, and later acquired technical senses (mathematics, computing, taxonomy).
