Here's how it works: what3words' global map divides the world into 57 trillion 9-square-meter areas, and assigns a unique, three-word name to each square. For example, the White House sits at engine.doors.cubs, while the Taj Mahal can be found at according.gloom.broads. (By virtue of their size, places like these actually have more than one set of names associated with them.) Just type in the three words on what3words' site and it shows you where to go. Or vice versa, if you want to learn the words; just pick a spot on the map or enter a street address or latitude and longitude coordinates.
