IPA: /ˈɪərldəm/
KK: /ˈɪrldəm/
A title or rank held by a nobleman, often associated with a specific area of land.
He was granted an earldom for his service to the king.
Earldom is formed from "earl" (from Old English "eorl", meaning chief or nobleman) and "-dom" (meaning state or condition). The word refers to the state or condition of being an earl, a noble rank in the British peerage system.
Think of an 'earl' as a nobleman and '-dom' representing a state or condition — together, they describe the noble rank of an earl.
