IPA: /ˈkɔːrkɪdʒ/
KK: /ˈkɔrkɪdʒ/
A fee that a restaurant charges for serving a bottle of wine or liquor that the customer brought from outside instead of buying from the restaurant.
The restaurant has a corkage fee of $20 for each bottle of wine you bring.
Corkage → It is formed from "cork" (from Old French *corque*, meaning the outer bark of a tree) and "-age" (a suffix indicating a related action or process). The word "corkage" refers to the fee charged for serving wine that a customer brings into a restaurant, relating to the action of using corked bottles.
Think of the 'cork' from a bottle and the '-age' indicating a process — corkage is the process related to using corked bottles, especially in dining.
