Overview
Danu is a Hindu primordial goddess. She is mentioned in the Rigveda to be the mother of the eponymous race of Danavas. The word Danu described the primeval waters that this deity perhaps embodied. In later Hinduism, she is described as the daughter of the Prajapati Daksha and his spouse Panchajani, and the consort of the sage Kashyapa.
Etymology
As a word for "rain" or "liquid", dānu is compared to Avestan dānu, "river", and further to river names like Don, Danube, Dnieper, Dniestr, etc. There is also a Danu river in Nepal. The "liquid" word is mostly neutral, but appears as feminine in RV 1.54.
Literature

In the Rigveda (I.32.9), she is identified as the mother of Vritra, the asura slain by Indra.
