The term 'PORTAL ENTRY' can be solved by the 8-letter word 'DOORKNOB'. A DOORKNOB is a handle used to open and close a door. It is typically attached to the outside of a door, and is operated by turning or pushing it. Doorknobs are usually made of metal, plastic, or wood, and come in a variety of shapes and sizes. They are an essential part of any doorway, providing a secure and convenient way to enter and exit a room.
