The term Viscount's Inferior refers to three different titles of nobility in the British peerage system. An EARL is the highest rank below a Duke and is usually given to a member of the royal family or a close advisor. A BARON is the lowest rank of the peerage and is typically given to a person who has made a significant contribution to society. A BARONET is a hereditary title, usually given to a person who has performed some service to the Crown. All three titles are considered to be inferior to a Viscount, which is the fourth rank in the peerage system.
