- noun a low outside door made of bars of wood or metal
- noun a door which leads to an aircraft at an airport
- noun a device for controlling the passage of water or gas through a pipe
- noun a circuit with many inputs and one output that works only when a particular input is received
- noun a device to prevent a lever from being moved to an incorrect setting
Cars & Driving
- noun a slotted plate in the shape of an H, controlling the movements of a gear lever in a sliding mesh gearbox (pre-1930s)
- noun a logical electronic switch whose output depends on the states of the inputs and the type of logical function implemented
- noun a connection pin of a FET device
- A usually hinged device of solid or open construction that is installed as part of a fence, wall, or similar barrier and that, when opened (either by swinging, sliding, or lifting), provides access through that barrier.
- noun the space between the bat and the batsman’s leg, especially when the batsman fails to keep bat and pad together when playing a forward stroke
- noun a set of stumps; a wicket (which did of course originally mean a type of gate)Citation ‘Upon the earliest appearance of the game in Ireland, the people applied the word Gate instead of Wicket’ (W. Bolland, Cricket Notes 1851)
- verb to dismiss a batsman by bowling him through the ‘gate’Citation ‘Lamb … was nicely caught at short leg by Rameez, and when Randall was “gated” by a Qadir googly, the writing was on the wall’ (Jack Bannister, WCM May 1984)
- A device or barrier which regulates the passage of a signal, charge, pulse, fluid, and so on.
- A circuit or device which carries out a logic function or operation. Such a circuit or device has multiple inputs and one output. Its output will depend on specified input conditions, such as a given combination of states. The three basic gates are the AND, OR, and NOT gates. Also called gate circuit (1), or logic gate.
- A circuit which determines if another circuit works. Also called gate circuit (2).
- In a field effect transistor, the electrode which controls the flow of current through the channel. Small variations in the voltage applied to the gate result in large variations in the current passing through a field-effect transistor. The gate is analogous to the base of a bipolar junction transistor. Its symbol is G. Also called gate electrode.
- A control electrode in a device such as a field effect transistor or thyristor.
- noun the part of a camera through which film passes to be exposed
- noun a barrier which can be opened and closed in order to allow access through a fence
- noun a movable barrier, usually on hinges, that closes a gap in a fence or wall
Origin & History of “gate”
Of the two English words gate, only one survives in general use. Gate ‘doorlike structure’ (OE) comes from a prehistoric Germanic *gatam, whose other descendants, including Dutch gat ‘hole, opening’, suggest that it originally denoted an ‘opening in a wall’ rather than the ‘structure used to close such an opening’. Irish has borrowed it as geata. The other gate ‘way, path’ (13th c.) now survives only in street-names, particularly in the north of England (for instance, York’s Micklegate and Coppergate); its other main meaning, ‘way of walking’, has been partitioned off since the 18th century in the spelling gait. It was borrowed from Old Norse gata ‘path, passage’, which comes ultimately from prehistoric Germanic *gatwōn.
