A hereditary ruler is a person who rules by virtue of their birthright, usually through a line of succession. The term can be broken down into three parts: GENE (4 letters), KING (4 letters), and DYNAST (6 letters). GENE refers to the genetic material that is passed down from one generation to the next, while KING is a title given to a monarch or sovereign ruler. DYNAST is a term used to describe a member of a ruling family or dynasty. Together, these three words form the term hereditary ruler, which describes a person who has inherited the right to rule.
