The title or rank held by a baronet, which is a hereditary honor in the British nobility, ranking below a baron.
He inherited the baronetcy from his father, becoming a member of the British gentry.
Baronetcy → It is formed from "baronet" (a title of honor in British nobility, derived from "baron" from Old French *baron*, meaning nobleman) and "-cy" (a suffix denoting a state or condition). The word "baronetcy" refers to the state or condition of being a baronet, a rank of nobility.
Think of a 'baronet' as a nobleman and '-cy' indicating a state or condition — so baronetcy means the state of being a nobleman.
