Ameretat (Avestan: 𐬀𐬨𐬆𐬭𐬆𐬙𐬁𐬙, romanized: amərətāt) is the Avestan language name of the Zoroastrian divinity/divine concept of immortality. Amerdad is the Amesha Spenta of long life on earth and perpetuality in the hereafter.
The word amərətāt is grammatically feminine and the divinity Amerdad is a female entity. Etymologically, Avestan amərətāt derives from an Indo-Iranian root and is linguistically related to Vedic Sanskrit amṛtatva. In Sassanid Era Zoroastrian tradition, Amerdad appears as Middle Persian 𐭠𐭬𐭥𐭫𐭣𐭠𐭣 Amurdad, continuing in New Persian as مرداد Mordad or Amordad. It is followed by Shehrevar.
