A gate or gateway is a point of entry to a space enclosed by walls, or a moderately sized opening in some sort of fence. Gates may prevent or control the entry or exit of individuals, or they may be merely decorative. Other terms for gate include yett and port. The word derives from the old Norse “gata”, meaning road or path, and originally referred to the gap in the wall or fence, rather than the barrier which closed it. A gate may have a latch to keep it from swinging and a lock for security.
