Roundel

A roundel is a circle that is used as a symbol or design element for different things, like logos or emblems. Just like you might draw a circle with crayons, people use roundels to make things look pretty or represent their group or company. Sometimes roundels have pictures or letters inside of them, like a soccer ball in a roundel to represent a soccer team, or a letter 'A' in a roundel to represent an airline company. It's like having a circle sticker on your water bottle, but instead of just being a sticker, it represents something important!
