In the February 1971 Word Ways, Delphi Knoxjaqzonville presented a list of words and names displaying vowel trigrams. However, she only considered the letters A, E, I, O and U as vowels, excluding Y. From five vowels 125 trigrams can be generated, while from six vowels the figure is 216. In her article, Miss Knoxjaqzonville gave examples of words and names which used most of the 125 AEIOU trigrams, and appealed to readers to search for words which used the 91 trigrams contianing the letter Y. I decided to respond to her appeal.
