KK: /ˈkændiˌflɔs/
A type of sweet treat made from spun sugar, often served on a stick and known for its light, fluffy texture and sweet flavor.
At the fair, I bought a big pink candyfloss that melted in my mouth.
Candyfloss is formed from "candy" (from Old French *candi*, meaning crystallized sugar) and "floss" (from Middle English *flos*, meaning a soft, fibrous material). The word describes a sweet treat made of sugar spun into a light, fluffy texture resembling soft fibers.
Think of 'crystallized sugar' ('candy') being transformed into a 'soft, fibrous' treat ('floss') — that's why candyfloss is a fluffy, sweet delight.
