Key Differences

The term "lord" is a title often granted to those belonging to the higher echelons of British nobility. It is generally a hereditary title, passed down from generation to generation, although life peerages can also be granted. The title is often associated with ownership of land, as many lords own estates.
Conversely, "sir" is a title given to individuals who have been knighted by the British monarch. Unlike "lord," the title "sir" is not hereditary and is not passed down through generations. Knights and baronets are generally people who have been recognized for their contributions to society, whether that be in the arts, sciences, or other fields.
One key distinction between "lord" and "sir" is in the scope of their use. The title "lord" is often accompanied by a territorial designation, linking the individual to a particular estate or region. "Sir," however, is a standalone title that precedes the individual's first name, and it does not indicate territorial influence.
While both "lord" and "sir" are forms of address that indicate a certain social status, they are used in different contexts and convey different types of respect and responsibility. While a "lord" may have political influence and substantial land holdings, a "sir" is generally recognized for individual achievements, often of a chivalric or humanitarian nature.
