There is an old Sanskrit verb mlai, first of whose recorded uses (in the rigveda) was in the context of tanning leather, but soon after the uses seemed to imply a meaning of faded or withered, or decayed, which might also have been its original meaning. The word mala which may be related to this root, meant filth, impurity or bodily excretions (related to Greek μἐλασ or Latin mălus etc.). The particle nis/nir indicated the senses of away, out of etc., so nirmala means pure, sinless, clean, or free from impurity. It is attested as a name of a divine figure already in the late Vedic period.
