Text from what3words website:

what3words is a global grid of 57 trillion 3mx3m squares.
Each square has a 3 word address that can be communicated quickly, easily and with no ambiguity.
Our geocoder turns geographic coordinates into these 3 word addresses and vice-versa.

Using words means non-technical people can accurately find any location and communicate it more quickly, more easily and with less ambiguity than any other system like street addresses, postcodes, latitude & longitude or mobile short-links.
