Previous issues of Word Ways have made much of words ending in the three letters -GRY. The subject has occurred several times over the years, but the fullest lists of -GRY words appeared in the November 1989 and February 1990 articles by George Scheetz and Murray Pearce, respectively. The exact number of -GRY words therein is unclear, but it's probably at least eighty. Uncertainty arises depending on whether "gry" and "Gry" are counted as one or two words, and so on.
