Explanation

A portal is a large and imposing gate or doorway. You’re likely to find a portal in a castle, in a cathedral, or even on an internet site. Portal can be used to describe other types of doorways, both literal and metaphorical. For example, portal can refer to a web page that provides access to other sites on the web. If you enjoy reading science fiction or fantasy, you may be familiar with the use of the word portal to mean “a doorway to another world.” The wardrobe in C.S. Lewis’s The Lion, the Witch, and the Wardrobe functions as a portal to the land of Narnia.
