Yeh (in Russian and Belarusian) or Eh (in Bulgarian, Macedonian, Serbian, and Ukrainian) (Е, е) is the sixth letter of the Cyrillic alphabet. It sounds like [e] or [ɛ], except in Russian and Belarusian, where it is said as [yeh] at the beginning of the word and as a palatised (soft) [yeh] in other cases.
It came from the Greek epsilon and is the same as the Roman E.
