Vexillology comes from the Latin word vexillum, meaning “flag” or “banner.” In English, it has been used since the 1950s to describe the study of flags, including their design, symbolism, and history. Vexillologists are often interested in the political, social, and cultural meanings of flags, as well as their aesthetic qualities. Today, vexillology is a popular field of study, and there are many organizations and societies dedicated to the study of flags.
