A review of previous word and letter counts in addition to the applications of these counts were reported. A comprehensive count of initial and terminal letters and bigrams was compiled based on the KuSera and Francis (Computational analysis of present-day American English. Providence: Brown Univ. Press, 1967) corpus of English words. The count included frequency of occurrence and versatility, or number of different words in which letters or bigrams occurred. It was shown how such counts can be used to describe "Englishness" and make predictions as to the information load of letters in words and pseudo words.Current research interest in the reading process and memory storage of words has necessitated an increased understanding of word orthography. This need has been facilitated by large capacity computers, which have replaced the tedious hand counts of English words and letter frequencies. In the present paper a review of current word and letter counts is presented, an analysis of contemporary and potential use of orthographic structure is made, and a comprehensive count of initial and terminal letters is presented.The examination of orthographic structure in a language is usually preceded by an analysis of the occurrence of words. The first modern count of American words was begun in the 1920s by Thorndike and resuited in a massive word frequency count done by hand called the "Thorndike-The authors wish to thank Karen Falke for writing the computer program for the present research.
