ASCII Character י
Hebrew letter YodYodh (also spelled jodh, yod, or jod) is the tenth letter of the Semitic abjads, including the Hebrew alphabet. Its sound value is /j/ in all languages for which it is used; in many languages, it also serves as a long vowel, representing /iː/. The term yod is often used to refer to the speech sound [j], a palatal approximant, even in discussions of languages not written in Semitic abjads, as in phonological phenomena such as English "yod-dropping". In gematria, Yod represents the number ten.
