The word slot is derived from the late 14c., and means “hollow at the base of the throat, above the breastbone”. It derives from the Old French esclot, of uncertain origin, and is also a variant of the Old Norse slod. The term was first recorded in the 1520s, and its modern sense of slot machine appeared in 1888. But before you play the game of Slot, you should know a little bit about its history.

First of all, what is a slot? The word slot comes from the 1747 meaning to cut or provide a hole. In 1888, it came to mean “drop a coin into a slot.” By 1940, it had acquired the meaning “fit something into a slot”. However, this older sense is now obsolete. For example, a slot is an opening in a copy desk occupied by the chief copy editor of a newspaper. An airplane wing may be equipped with slots to improve airflow.

Each utterance may include multiple slots, or none. By specifying the number of rooms needed or the number of nights, you can map the slots to entities in the utterance. You can also define custom slots to map to other types of entities, like date and type of room requested. Once you’ve mapped slots, you can add utterances with them. In the Slots tab, simply enter the name of the slot you want to map to.
