In the February 1991 Word Ways, Darryl Francis exhibited a type-collection of mtalleges (letter-swap transposals, as sLAve to sALve, or sKaTe to sTaKe) of two through ten letters. This article examines eight-letter metalleges in more detail, listing all that can be found in the Official Scrabble Players Dictionary. In general, adjacent letter-swaps are commoner more than distant ones, especially those that occur near the start or the end of a word. The full list of 283 OSPD metalleges is given below.
