I get a perhaps similar kick out of reading proto-indo-european word lists: https://en.wikipedia.org/wiki/Indo-European_vocabulary https://en.wikipedia.org/wiki/Indo-European_vocabulary English "heart" is in French, "coeur", and in Greek, "kardia". Unrelated? No! In Proto-Indo-European we think it was "k̂erd"! Soften the leading k, stop voicing the final d, jiggle the vowel, and you get "heart". Lose the final d and you get "coeur". Jiggle the vowel, add a trailing vowel for streamlining, and you get "kardia". Better yet, soften the leading k and you get "hṛd", the Sanskrit word. Add a trailing vowel, and you get "hŕday", the Hindi word in use today (or so wiktionary tells me).
