Deglutition is a noun that refers to the act or process of swallowing.

The Latin word deglutire (de glue TIRE ay) means ’to swallow down.’ Deglutition reached English in the mid 17th century where it hold pretty firmly to it original meaning. Here’s an example:

The patient was unable to consume food because of how bloated his throat was. A throat that swollen can often make deglutition difficult.
