Fun fact! This root is only attested once in North Germanic ancient and modern: the province Medelpad ‘Middlepath’ in northern Sweden.
It was probably borrowed during the Migration Period from contacts with Iranian tribes like Alans and Sarmatians.
‘Path’ has a very strange etymology.
Old English pæþ (pronounced exactly the same) from PGmc *paþaz, still meaning path. But … shouldn’t the Germanic descendant from PIE *póntoh₁s be *fanþaz?
This has led to the suggestion that it is a loan from Proto-Iranian *pántaHh (path).
