Transcription of the two interviews from the Indo-european video.
1st Interview
He was a judge (Samuel L. Jones) who went to India in 1783 but he studied languages, oriental languages before he went and when he got to India he became very interested in learning Sanskrit, which is the language of ancient India. Which was first written about 500 AD. And then he realised he made this great discovery that Sanskrit resembles, in some way, has relationships with Greek and Latin, and other languages. He gave a very famous discourse in which he said this was sprung from some common source.
2nd Interview
The question is how can you tell that the languages you're looking at reflect a single original language, and therefore form a family. The only way you can do that is by finding systematic similarities between these languages in every area of the grammar, similarities in their sounds, similarities in their inflections, similarities in the syntax, and so forth, and the similarities have to be very precise and have to be interlocking for the assertion that these languages form a family to be believable. You take a look at an English word like “tooth”, and see that in Hindi it's “dant”, and by itself that doesn't mean very much. But you take a look at the English “ten” and it shows up in the Hindi “das”. You see the same pattern emerging and you've got an initial “t” in English, and an initial “d” in Hindi. When you find that the word “two”, the numeral, in English shows up in Hindi as “do”, you've got, once again, an initial “t” in English and an initial “d” in Hindi. And you begin to think that perhaps this is not an accident.
