'firm-owned' originates from the combination of 'firm,' meaning a business or company, and 'owned,' the past participle of 'own,' meaning to possess.

'Firm' comes from the Latin word 'firmus,' meaning strong or stable, and 'own' comes from the Old English 'āgan,' meaning to possess.

Initially, 'firm' referred to a business entity, and 'owned' meant possession. Together, they have consistently meant 'owned by a business entity.'
