Esquire

Esquire is usually a courtesy title. In the United Kingdom, esquire historically was a title of respect accorded to men of higher social rank, particularly members of the landed gentry above the rank of gentleman and below the rank of knight. Some sources state that the title was bestowed on "candidates for knighthood in England". It was also used with respect to other dignitaries, such as justices of the peace, sheriffs, and sergeants.
