The word "stewart" has its roots in Old English and Old Scottish. The term originated from the Old English word "stigweard", which was a compound word combining "stig", meaning "household" or "dwelling", and "weard", meaning "guardian" or "keeper". In Old Scottish, the word evolved into "steward", referring to a person responsible for managing the estate or household of a noble or royal family.
Over time, the spelling shifted to "stewart", which became a hereditary surname associated with a prominent Scottish noble family. The Stewart family eventually produced a line of Scottish monarchs, beginning with Robert II in the 14th century. As a result, "Stewart" became a common Scottish surname and retained its association with the stewardship role.
