Flags are symbols, often made of fabric, that are used to represent countries, organizations, or ideas. Typically featuring distinctive colors, patterns, or emblems, flags serve as a powerful means of communication and identity. They can be used in a variety of contexts, such as representing nations during international events, signaling messages in maritime settings, or expressing support for social causes. Flags are also used ceremonially, like during parades, official functions, or memorials, where they can evoke pride, unity, or remembrance. Overall, flags are versatile tools that convey meaning, identity, and affiliation in both practical and symbolic ways.
