Why is letter E the most common used letter?

It is well known that the letter E is the most common letter. In my corpus, I found 12.478% of letters is letter E. What makes me surprise was 64.219% of words contain the letter E. I also found that 12.384% of words end with a silent E.

Then I wonder why is the letter E so common in English spelling? Is it because of the silent E to some extent?

Answer

While this doesn’t speak to the etymological reasons for why ‘e’ specifically is the most frequent letter, there is actually a very interesting statistical reason that there is such a letter: Zipf’s law.

Given some corpus of natural language utterances, the frequency of any word is inversely proportional to its rank in the frequency table.

Zipf’s law was originally discovered with regards to Word frequency (e.g. the word ‘The’ is the most common word in the Brown Corpus), but also applies to many frequency and ranking comparisons, especially where humans are involved in the ranking process.

Essentially, the easiest to recognize, most generally useful sounds and concepts are used more often while the more specific, harder to articulate sounds and concepts are used less often. This generally follows a “long tail” logarithmic curve.

As for the letter ‘e’, it often represents very easy to pronounce vowels, and orthographically it is also used in English orthography to “silently” affect another vowel (e.g. ‘ate’ vs. ‘at’). Added up, it’s a pretty useful little letter!
