'Path' may link to Sanskrit 'panthah' (road) — a track worn into the earth by repeated footsteps.
A way or track laid down for walking or made by continual treading.
From Old English 'pæþ' (path, track), from Proto-Germanic *paþaz (path), of uncertain further etymology. It may be related to Avestan 'pantā' (way, path) and Sanskrit 'pánthāḥ' (path, road, journey), from PIE *pent- (to tread, to go), but the phonological details of this connection are debated. The word is common in all West Germanic languages but absent from North Germanic, where 'stig' (modern English 'sty' as in 'pigsty') was used instead. Key
The word 'pathology' has nothing to do with 'path' — it comes from Greek 'pathos' (suffering), not from the Germanic word for a track. This is a pure coincidence of English spelling. But 'path' itself may be distantly related to Sanskrit 'pánthāḥ' (road), which would make it a cousin of the ancient Indo-Iranian concept of the cosmic path.
