In our article "Cardinal Transposals" in the November 1975 issue of Word Ways, we sought transposals for each of the number-names from ONE to TWENTY (by tens, from TWENTY to ONE HUNDRED). Many of these words were rare or obsolete, last used centuries ago. If one is permitted to add one or more letters before transposing, it is possible to locate much more common words corresponding to the number-names.
