Even though I have a fairly large vocabulary, I do not know many words which are one-letter words.  Ask me to identify three- and four-letter words, and I am at ease.  One letter?  The only common single letter words are "a" and "I"!  However, I was fortunate to hear about a book which could be my saving grace, One Letter Words--A Dictionary, by Craig Conley.  I felt my confidence begin to soar because with the help of this dictionary I should easily be able to count all one-letter words in any given word, or could I?  Being a bit of a skeptic, I tested my skill with the word "ait".  "I" and "a" are legitimate, but what about "t"?  Sure enough, Mr. Conley provides 58 instances in which "t" is used as a word.  As an example, "it suits you to a T" uses "t" as a word.  Hallelujah!  But "ait" is a fairly simple word.  What about "Mozambique"?  I feel a time-consuming project ahead.  Actually, the dictionary is foolproof.  There are thirty-five examples using the word "z" and even twenty-seven examples of the word "q".
