00:00A gate or gateway is a point of entry to or from a space enclosed by walls.
00:05The word is derived from Proto-Germanic asterisk gatan, meaning an opening or passageway.
00:11Synonyms include yet, which comes from the same root word and portal.
00:16The concept originally referred to the gap or hole in the wall or fence,
00:21rather than a barrier which closed it. Gates may prevent or control the entry or
00:26exit of individuals, or they may be merely decorative. The moving part or parts of a
00:32gateway may be considered doors, as they are fixed at one side whilst opening and closing like one.
00:38A gate might have a latch that can be raised and lowered to both open a gate or prevent it
00:43from
00:44swinging. Gate operation can be either automated or manual. Locks are also used on gates to increase
00:51security. Larger gates can be used for a whole building, such as a castle or fortified town.
00:58Doors can also be considered gates when they are used to block entry as prevalent within a gatehouse.
