The Study of Flags Is Called Vexillology. Vexillology as a word is derived from the Latin vexillum, a term used by the Romans to refer to a kind of standard with a fabric hung from a horizontal crossbar on a pole. It is the nearest equivalent in the classical languages to what we call a flag today.
