"Arch" can be both a prefix and a root.
As a prefix, "arch-" means "chief" or "principal." Examples include words like "archbishop" (the chief bishop) and "archenemy" (the principal enemy).
As a root, "arch" comes from the Greek word "arkhē," meaning "beginning" or "origin." It is used in words like "archaeology" (the study of human history and prehistory through excavation and analysis of artifacts) and "archetype" (a typical example or original model of something).
