What are the most used letters in the English alphabet?

The most frequently used letter in the English language is e, which has 12.49% of the total. This is followed by t (9.28%) and a (8.4%)

The gold and bronze medals are unsurprisingly but a surprise to see 't' to be up there on the winners rostrum. E is the champion in other languages, too. George Perec famously wrote a detective novel in French without an es (as it were) La Disparition (1969). This was then translated into English by Gilbert Adair as A Void.
