Eta /ˈiːtə, ˈeɪtə/ (uppercase Η, lowercase η; Ancient Greek: ἦτα ē̂ta [êːta] or Greek: ήτα ita [ˈita]) is the seventh letter of the Greek alphabet. Originally denoting the 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. Eta was derived from the Phoenician letter heth . Letters that arose from eta include the Latin H and the Cyrillic letter И.
