KK: /sʌbˌdɛb.jʊˈtɑːnt/
A young girl, usually in her teenage years, who is preparing to be introduced to society, often at a formal event called a debut.
The subdebutante wore a beautiful dress to the ball, excited for her upcoming debut.
Subdebutante → It is formed from "sub-" (meaning under or below) and "debutante" (from French, meaning a young woman making her first appearance in society). The term refers to a young woman who is below the status of a full debutante, often participating in social events but not yet fully introduced to society.
Think of a young woman who is 'under' ('sub-') the status of a debutante, meaning she is not yet fully introduced to society.
