 Context examples 

The first message submitted to me was so short that it was impossible for me to do more than to say, with some confidence, that the symbol XXX stood for E. As you are aware, E is the most common letter in the English alphabet, and it predominates to so marked an extent that even in a short sentence one would expect to find it most often.
