I've wondered about ay and shy, but figured it's just coincidence.
My Thai is not that good. Probably only 500 words or so and my accent is terrible. But I am unclear about ay and shy. Can you give me a clue?
Plus I wasn't asserting that they were similar because they came from some 'proto-language' I was just making an observation that very, very different languages had some words that sounded rather similar and I thought it interesting.
Mare - Mother or often in English Ma
Pore - Father or again often Pa
Fi - fire
Those are the only non-loan words that overlap that I've come across
It is interesting that there are any words in common of course
