Wt is mean by uluntha paruppu and kundu ulunthu in English?

"Ulundha paruppu" and "kundu ulunthu" are both Tamil words that refer to different types of lentils:

* Ulundha paruppu is the Tamil name for black gram or urad dal. It's the whole, unsplit lentil.

* Kundu ulunthu is the Tamil name for split black gram. This means the lentil has been split, making it easier to cook.

So, they're essentially the same lentil, just in different forms.
