ASCII Character ן
Hebrew letter final NunNun is the fourteenth letter of the Semitic abjads, including the Hebrew alphabet. Its numerical value is 50. It is the third letter in Thaana (ނ), pronounced as "noonu". In all languages, it represents the alveolar nasal /n/. Nun is believed to be derived from an Egyptian hieroglyph of a snake (the Hebrew word for snake, nachash begins with a Nun and snake in Aramaic is nun) or eel. Nun, like Kaph, Mem, Pe, and Tzadi, has a final form, used at the end of words. Its shape changes from נ to ן. There are also nine instances of an inverted nun (׆) in the Tanakh. In gematria, Nun represents the number 50. Its final form represents 700 but this is rarely used, Tav and Shin (400+300) being used instead.
