In two earlier Word Waysarticles published in August 1975 and February 1976, I proposed a nomenclature for very large numbers, going far beyond the vigintillion (ten to the sixty-third power) commonly regarded as the outer limit. In this article, I introduced some changes to make my proposed nomenclature more consistent with the modern system of Latin cardinal number names, as given on page 128-9 of Ernest Hettich and A.G.C. Maitland's Latin Fundamentals (New York: Prentice-Hall, 1950). In particular, the number name millillion, formerly used to represent the number one followed by 3(1000) + 3 zeros, has now been delayed until 3(1000000) + 3 zeros appear - a much more appropriate location.
