The appellation "lord" is primarily applied to men, while for women the appellation "lady" is used. This is no longer universal: the Lord of Mann, a title previously held by the Queen of the United Kingdom, and female Lord Mayors are examples of women who are styled as "Lord".

A Lord (Laird in some Scottish contexts) is a person who has power and authority. Women will usually (but not universally) take the title 'Lady' instead of Laird or Lord, but there is an example of a female Lord: Lord of Mann, the ruler of the Isle of Man.
