स्रुति

From Proto-Indo-European *sréw-ti-s ~ *sru-téy-s (“act of flowing; a stream”). By surface analysis, स्रु (sru, “to flow”) +‎ -ति (-ti). Cognate with Ancient Greek ῥύσις (rhúsis), ῥεῦσις (rheûsis).

The term then developed a meaning "road, path", from "stream" → "course (of a stream)" → "path, way".

     दूरम् अधि स्रुतेर् अज ॥

     apa tyaṃ paripanthinaṃ muṣīvāṇaṃ huraścitam.
     dūram adhi sruter aja.

     He who lurks about the path we take, that robber with a guileful heart:
     Far from the road chase him away.
