What is a Slot?
A slot is a narrow depression or aperture, often in a machine or on a piece of clothing. Its name comes from the Old French esclot, which was an uncertain word, but has been related to the English word sleuth. The word was first used in the late 14c., but the machine-playing meaning dates from 1888. Slots can have a variety of purposes, including receiving a piece or sliding something in.
Today, slot systems are mostly used in field hockey, but they can also be found in ice hockey. Slots are also the fourth position in a flying display. In ice hockey, the slot extends towards the blue line, and they are often found behind the goal line. Their name is related to the Latin word slot, which means to cut or provide a slot. The term has also gained popularity as a noun in other contexts, such as the sense of fitting or taking a position. This latter meaning is now obsolete.
