A collapsible canopy is an UMBRELLA-like structure that can be easily folded and stored away when not in use. It is typically made of a lightweight material such as nylon or polyester, and is designed to provide shade from the sun or protection from rain. The term 'collapsible canopy' is often used interchangeably with 'UMBRELLA, ' which is an 8-letter word that is also used to describe this type of structure.
