KK: /ˈɑrtʃˌduːtʃɪs/
A noblewoman of high rank, particularly in Austria, who holds an archduchy or is the wife or widow of an archduke.
The archduchess attended the royal ceremony in a beautiful gown.
Archduchess → It is formed from "arch-" (meaning chief or principal) and "duchess" (from Old French *duchesse*, meaning a female duke). The term refers to a principal or chief female noble, specifically the wife of an archduke.
Think of 'arch-' meaning chief, and 'duchess' as a female duke. This helps you remember that an archduchess is a chief female noble.
