A vexillologist is a person who studies flags, their history, symbolism, and usage. This field of study encompasses various aspects, including the design, colors, and patterns of flags, as well as their cultural significance. Vexillologists often analyze national flags, state flags, and other types of banners used in different contexts. The term comes from the Latin word "vexillum," meaning flag or banner. Vexillology can also involve the examination of historical flags, such as those used in battles or by specific organizations. Many vexillologists contribute to the field through research, writing, and public education about the importance of flags in society.
