Greek - hydor/nero
Tamil - neer/neeru

"Ainu" to Ain/Ein (Arabic/Hebrew wellspring)
"Utari" to udra/udar/hadra/hydr/watery (sam-udra = ocean)
Conversely, in Malay, air/ayer = water to drink, but udara = air to breathe (sum-atra island)
Bilad al Sudan (Arabic) land of black, likely from soil color, black = rich wet organic soil vs dry yellow red sand desert of Egypt. So Sudan may be derivative/source of udan (water).
