A narrow opening for admitting something, such as a coin or a letter. Also called a slot, slit, aperture, or channel. Often used as part of an address or a telephone number: He dialled his old number, but got a different time slot. In sports, a position on the team’s offensive roster between the wide receiver and the tight end. The player who lines up in the slot is often quicker than the other wide receivers, and can be more effective when running a spread offense.

A table that displays information about a slot’s symbols and payouts. It will usually include a picture of each symbol, alongside how much you can win for landing (typically) three or more of them on a payline. It will also detail if the slot has any bonus features or other special functions. Typically, the pay table will be themed to match the slot’s overall design.

In aviation, an allocated space at an airport or other location for an aircraft to take off or land, as authorized by air-traffic control. A slot is normally assigned for an hour or so in advance of the scheduled departure time. Occasionally, the slot may be reserved for a more urgent flight; this is known as a priority slot. The term is also applied to the position of an aircraft in a queue of other planes waiting at the same gate. In ornithology, the narrow notch in the tips of certain bird’s primaries that during flight helps to maintain a smooth flow of air over the wings.
