Zully/Corvin :
The What3Words system works by dividing the Earth’s surface into a grid of 3 m × 3 m squares, each assigned a unique integer index. A curated dictionary of around 40,000 short, distinct, and non-offensive words is prepared for each language. The index of a square is converted into a base‑N number, where N is the dictionary size, and split into three parts, each corresponding to one word. A scrambling algorithm is applied so that similar word combinations are geographically far apart, reducing confusion. To encode a location, the algorithm maps the grid index to three words; to decode, it maps the words back to their dictionary indices, recombines them into the original integer, and converts that back into coordinates. This approach makes location references human‑friendly, easy to remember, and less error‑prone than raw GPS coordinates, while still being precise to within a few meters.
