The word slot was first used in the 17th century, meaning a place to drop a coin. The meaning of “to take a position in or fit into” appeared in 1888, and the meaning “to receive something” followed in 1966. The meaning of “slot” has since become obsolete. A slot is a narrow opening in a hockey rink, and is used to receive a puck or pucks in the offensive zone. A slot is also a place in an airplane, where it can improve airflow.

If the user enters a word or phrase in a slot, it will be mapped to that word or phrase. The Dialog Engine recognizes multiple words for the same slot, so if you say “Big Apple”, it will map to New York. Then, if you choose “New York,” you can insert other synonyms to the selected word/phrase. You can edit or delete the slot in the Slots tab by clicking on it.

The slot HTML element is a key element in Web Components. It is the basic building block for separate DOM trees. If you want to use a single slot for multiple functions, it must have a name attribute, otherwise it is known as a named slot. For this reason, it is a common element in Web Components. There are two types of slots: global and local. In fact, a slot may be referred to as a named slot when it has a name attribute.
