The Indian word for house is Wigram which is a corruption of the Greek word oikos.
According to proto-Indo-European theory *wey-k- is the root of all indo-European words meaning settlement and of the Greek word oikos which in proto-Greek was spelled with a w to give (w)oikos therefore oikos is origin of the word wigwam.
From the cognates below it is clear that Wigwam is the accusative of (W)oikos or (W)oikon.

Why would the American Indians have a word for river which is the same word as the Greeks used i.e Potomac. Potomac is a Greek word coming from Greek
potamos . Because there were Greeks and Vikings in America long before Columbus. And there are many other Greek words in American Indian languages.
The English word River is a corruption of Fluvium which occurred in Mycenaean times when R and L were interchangeable and were not fully distinct from n and m. Fluvium is a
corruption Potamos as well with P interchangeable with Fl and Tam interchangeable with Vium. But don't expect anyone tell you that there were Greeks in Roman and Britain in Mycenaean times like all the Greek historians tell us.
From Egyptian inscriptions we know the Minoans called themselves Kittim, Kyftu, Kyferu or Keferim ie. Kypraioi. They must have been Cypriots.
