Ė ė is the 9th letter in the Lithuanian alphabet, and is also used in the Colognian language of Cologne, Germany, and Cheyenne language.
It was coined by Daniel Klein, the author of the first grammar of the Lithuanian language.
This character is also used in strict Library of Congress transliteration when transliterating the Cyrillic letter Э э into the Latin alphabet.
This character is also used in Croatian to denote the old yat alongside the more usual ě.
Its pronunciation in Lithuanian is [eː], contrasting with ę, which is pronounced a lower [ɛː] (formerly nasalized [ɛ̃ː]) and e, pronounced [ɛ, ɛː].
