Step 1 : Introduction to the question "What is the most common letter in the English language?"
...The most common letter in the English language is the letter "E." It appears more frequently than any other letter, both in written and spoken forms of the language. This dominance is evident in everything from classic literature to everyday conversation, as well as in word construction and grammar. Many of the most frequently used words, such as "the," "he," "she," "we," and "me," contain the letter E. According to an analysis done by Lexico, the letter "E" makes up 11.16% of the Oxford Dictionary — 2% more than the next most common letter.
