The origins of the Sinhala language are probably linked to the Magadhi of the Asokan (northern) Parkrit ( early Brahmi script), and Pali, while Tamil is linked to a southern prakrit (with a very similar Brahmi script).
However, the two forms of Brahmi, and their Prakrit forms are themselves very close.
On the other hand, the sinhala word "Attana" refers to a plant species (Latin Dathura Alba, or Datura metal, Tamil "Umaththai").
Its occurrence in Sinhala place names is well established.
