A slot is a small, narrow opening or groove in something. It’s also the name of the unmarked space between the face-off circles on an ice hockey rink. There are many different uses for slots. In engineering, a slot is often used in building structures to improve the flow of air. It is also used in architecture to allow for more flexible design.
A slot can also be an occupation or assignment. For example, a chief copy editor might fill a slot for a twenty-year-old magazine. Another example is an airport or air-traffic authority slot. In a workplace, a slot may be an open job position. A slot can also be a linguistic jargon that means “to go.”
