I was just looking at the words for "ball" in many languages.
I noticed that Armenian has a word
գունդ gund and Hindustani has a word
I didn't spot any other language with a similar word, including Greek and Persian. The etymology of the latter word is given as Sanskrit
I realize the rate of coincidence is high in such short words and that the languages have other words in the semantic area of "orb", "sphere", etc. But the fact that they're both Indo-European and the lack of other languages with similar words made me wonder.
