For almost fifty years Webster's New International Dictionary of the English Language, Second Edition, Unabridged, has been the official authority in most word-building puzzle contests. This huge tome of 2987 pages is a veritable storehouse of information; the edition I own and treasure is actually an encyclopedia. My sympathetic wife first purchased it in 1933 from an unemployed father, and I paid for it in monthly installments. Those regular payments helped provide for some of his physical needs for a time, while the book's contents have nourished my mind all these years.
