[S.T.D.]

You can also use "punarcchi" (and related words such as "punartal") in non-grammatical contexts, to refer to meeting or union. In ancient Tamil prosody, for example, one of the poetical divisions which dealt with one lover longing for the other and grieving over their separation was called புணராவிரக்கம் (punaravirakkam).

I think, virakkam, is a Samskritham word again, which is "Viraham". I am sure there shd be a Thamizh word for this too...

I have veryu very very poor knowledge about Thamizh literature and grammer. Whaterver, said and argued, after seeing the available quotes from Literature, I feel this, that in ancient days, our ancestors didn't hesitate to use other language's words and they meant no superioarity or inferiority. I think, only in the middle ages, due to some mal-elements, unncessary politcs were created and in resolving this politics, we hav lost many valuable things....
