References:МССНЯ 346. ND 1759 *ṗarV 'fly, jump' (with dub. Alt. (TM) and incorrect Drav. *pād_-); 1785a *ṗar(y)V 'to run, flee' (Drav. + Georg. 'escape'); 1786 *[ṗ]ur(y)V 'wing, feathers' (IE + Georg. prte + Drav. pūr- + Alt.). At this point there seems to be not enough evidence to distinguish these three roots (other than Drav. and perhaps TM).
