The word "Bannerel" originated from the Middle English term "banerel", which in turn can be traced back to the Old French word "banierele". It ultimately comes from the Latin word "bandum", meaning "banner" or "a standard". The suffix "-el" in Middle English was used to form a diminutive, indicating a smaller or lesser version of something. Therefore, "Bannerel" can be understood to refer to a small or lesser banner.
