KK: /ˈprɛpiər/
More stylish and neat, often associated with a certain social class or lifestyle that values traditional clothing and appearance.
She dressed in a preppier style for the party, opting for a polo shirt and khakis.
Preppier is derived from "prep" (short for preparation, originating from the word "preparare" in Latin, meaning to prepare) and the suffix "-ier" (indicating a comparative form). The term "preppier" refers to someone who is more prepared or exhibits a style associated with preparation, often linked to a specific fashion or lifestyle.
Think of 'prep' as being about preparation and 'ier' as making it a comparison — so preppier means someone who is more prepared or stylishly ready.
