What are the most used letters in the English alphabet?

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

Why these letters?

The gold (E) and bronze (A) medals are perhaps predictable. Every standard English word has a vowel - only 'psst' appears in the OED and 'psst' would not be in most lists of standard words! It is more surprising to see T up there on the winners rostrum. 

E is the champion in other languages, too. George Perec famously wrote a detective novel in French without it  La Disparition (1969). This was then translated into English by Gilbert Adair as A Void.
