A slot is a grammatical element with a specialized function in tagmemics. It can fit any morpheme sequence. For example, a slot is an assignment, job opening, or other special purpose. For example, the chief copy editor has occupied a slot for over 20 years. Another example is an airport slot authorized by an air-traffic authority.

The slot is also referred to as a scoring area on the ice in ice hockey. It is also the fourth position of the flying display. There are several types of slots and the term is related to the verb sleutana and is cognate with the German Schloss. Despite its many uses, a slot does have a few disadvantages.

Many states restrict slot machines. In some states, like Alaska and New Jersey, the slot machines are only permitted in casino establishments, or at certain locations in bars and pubs. In other states, such as Indiana, Louisiana, and Michigan, casino-style gambling is only permitted on riverboats or barges. After Hurricane Katrina, the barge requirement was lifted in Mississippi. In other states, like Delaware, slot machines can be found at three race tracks that are regulated by the state lottery commission. Some states even permit casinos with up to five slot machines.

Slot receivers are versatile. They can go inward or straight down the field. This type of receiver is growing in prominence in the NFL. Players like Tyreek Hill and Branden Cooks can stretch the defense vertically with their speed. They are also effective in the catch-and-run game and are excellent for shorter routes on the route tree. They can also run slants and quick outs.
