'E' is the fifth letter in the Latin alphabet. Its name in English is pronounced . The letter ''E'' is the most commonly used letter in the English language.[1]
'E' is derived from the Greek letter epsilon which is much the same in appearance (Ε, ε) and function. In etymology, the Semitic ''hê'' probably first represented a praying or calling human figure (''hillul'' jubilation), and was probably based on a similar Egyptian hieroglyph that was pronounced and used quite differently. In Semitic, the letter represented (and in foreign words), in Greek ''hê'' became Εψιλον (Epsilon) with the value . Etruscans and Romans followed this usage. Arising from the Great Vowel Shift, English usage is rather different, namely (derived from in "me" or "bee") whereas other words like "bed" are closer to Latin and other languages in usage.
Like other Latin vowels, E came in a long and a short variety. Originally, the only difference was in length but later on, short e represented . In other languages that use the letter E or e, it represents various other phonetic values, sometimes with accents to indicate contrasts (e ê é è ë ē ĕ ě ẽ ė ẹ ę ẻ).
Digraphs starting with E are common in many languages to indicate diphthongs and monophthongs, such as EA or EE for or in English, EI for / in German, or EU for in French or in German.
At the end of a word, E is very often silent in English (silent E), where old noun inflections have been dropped, although even when silent at the end of a word it often causes vowels in the word to be pronounced as diphthongs, conventionally called long vowels (compare as a noun ''rat'' and as a verb ''rate'').
''For the number that is base of the natural logarithm (≈ 2.71828), see e (mathematical constant).''
The letter 'E' is the most common letter in the English language and many other related languages, which have some implications in cryptography. This also makes it a difficult and popular letter to use when writing lipograms.
★ The upper case letter ''E'' is often used to represent energy, most famously in the formula "E=mc2".
★ The lower case letter ''e'' is used to represent the electron or the elementary charge.
In Unicode the capital E is codepoint U+0045 and the lowercase e is U+0065.
The ASCII code for capital E is 69 and for lowercase e is 101; or in binary 01000101 and 01100101, correspondingly.
The EBCDIC code for capital E is 197 and for lowercase e is 133.
The numeric character references in HTML and XML are "E" and "e" for upper and lower case respectively.
