'landlord' originates from Middle English, specifically the words 'land' and 'lord', where 'land' meant 'ground or territory' and 'lord' meant 'master or ruler'.

'landlord' changed from the Old English word 'landhlaford' and eventually became the modern English word 'landlord'.

Initially, it meant 'master of the land', but over time it evolved into its current meaning of 'owner of rental property'.
