Tefnut
Tefnut
Tefnut is a goddess of moisture, moist air, dew and rain in Ancient Egyptian religion. One of the Egyptian Nine Ennead She is the sister and consort of the air god Shu and the mother of Geb and Nut.
Literally translating as "That Water", the name Tefnut has been linked to the verb 'tfn' meaning 'to spit' and versions of the creation myth say that Ra (or Atum) spat her out and her name was written as a mouth spitting in late texts. Unlike most Egyptian deities, including her brother, Tefnut has no single ideograph or symbol.
