Esquire

Esquire (, ; abbreviated Esq.) 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.

The 1826 edition of William Blackstone's Commentaries on the Laws of England reiterated that "the title should be limited to those only who bear an office of trust under the Crown and who are styled esquires by the king in their commissions and appointments; and all, I conceive, who are once honoured by the king with the title of esquire have a right to that distinction for life." By the early 20th century, however, esquire was being used as a general courtesy title for any man in a formal setting, with no precise significance, usually as a suffix to his name, and commonly with initials only. In the United Kingdom today, esquire is still occasionally used as a written style of address in formal or professional correspondence. In certain formal contexts, it remains an indication of a social status that is recognised in the order of precedence. In the legal profession, the title is only available for barristers.
