IPA: /ˈpɒt.lʌk/
KK: /ˈpɑtˌlʌk/
A gathering where each person brings a dish of food to share with others.
We had a potluck dinner, and everyone brought their favorite dish to share.
Potluck is formed from "pot" (from Old English *pott*, meaning a container for cooking) and "luck" (from Middle English *luc*, meaning chance or fortune). The term refers to a meal where each guest brings a dish, relying on the chance of what others will provide.
Imagine a gathering where everyone brings a dish in a 'pot' — that's why 'potluck' means a meal based on the 'luck' of what others contribute.
