means Red wine warmed and steeped with spices like cinnamon, cloves, and citrus, usually sweetened — a winter drink meant to be sipped hot.

from The 'wine' part is plain enough, but 'mulled' is the mystery guest — its origin is genuinely uncertain. It surfaces in English around the 17th century meaning to heat and spice a drink, and may be related to an older English 'mull' meaning to soften or dull (as mulling softens wine's bite with warmth and sugar), but no one can trace it further back with confidence. The practice itself is ancient — Romans spiced and warmed their wine too — the English word just arrived later to name what people were already doing to survive the cold.
