Mångha (måŋha) is the Avestan for "Moon, month", equivalent to Persian Māh (ماه; Old Persian 𐎶𐎠𐏃 māha). It is the name of the lunar deity in Zoroastrianism. The Iranian word is masculine.[1] Although Mah is not a prominent deity in the Avestan scripture, his crescent was an important symbol of royalty throughout the Parthian and Sassanid periods.
The Iranian word is cognate with the English moon, from PIE *mēns
