A new hunt begins...
Between 1998 and 2002, the Three Letter Abbreviation Hunt managed to track down meanings for every single one of the 17,576 possible three-letter combinations.
The bigger challenge began in 2004- the hunt for all the four letter abbreviations.
There are 456,956 to be found, so there's still a very long way to go. But with your help, this can be done.
