A beanie is a type of knitted cap that is worn to keep the head and ears warm during cold weather. There are several synonyms for this popular accessory, including tuque, skullcap, knit cap, head warmer, wool hat, and toboggan. The word tuque is a Canadian term that is used in French-speaking regions. Skullcap refers to a tight-fitting beanie that covers the entire head, while a knit cap generally has a softer shape and may include a pom-pom on top. A wool hat is typically thicker and warmer than a beanie, while a toboggan is a slang term commonly used in the southern United States to refer to a knitted cap.
