Our 26 letters allow 676 possible bigrams, and various searches have been made to find as many of these as possible in certain logological categories, particularly at the beginning and at the end of words. What follows is an attempt at discovering as many as possible of the 676 pairs straddling the hyphen in compound words. Webster's Second Edition (NI2) viewed hyphenated words more favorably than Webster's Third (NI3). In spite of the tendency to drop hyphens from the newer edition, it appears that our newest words, as found in the Addendum to NI3, have a greater likelihood of hyphenation than even NI2.
