THE letter 'E' is the most common letter in the English language, but there was an author in the late 1930's who wrote an entire book without using the letter. Verdict:TRUE“E” is the most commonly used letter in the English language, so it is no mean feat to write a novel in English, without using this letter. In 1939, American author Ernest Vincent Wright published Gadsby, a 50,000-word novel that ditched this vowel. This isn’t the only book that is a lipogram - a written work in which a particular letter is intentionally omitted. Partly inspired by Gadsby, the French novelist Georges Perec wrote La Disparition (in French) without using the letter "E", in 1969.
