Η


Eta (uppercase Η, lowercase η; Ancient Greek: ἦτα Greek pronunciation: [êːtaː] or Modern Greek: ήτα Greek pronunciation: [ˈita]) is the seventh letter of the Greek alphabet. Originally denoting a consonant /h/, its sound value in the classical Attic dialect of Ancient Greek was a long vowel [ɛː], raised to [i] in hellenistic Greek, a process known as iotacism.

In the system of Greek numerals it has a value of 8. It was derived from the Phoenician letter heth Phoenician heth.svg. Letters that arose from eta include the Latin H and the Cyrillic letter И.
