And the Romans, in good fashion, borrowed their word "barbarus" from the Greek "barbaros", meaning the same thing. Etymologists are unsure if the "bar-bar" comes from the tendency of Germanic languages to use the hard "r" sound, as opposed to the Mediterranean trilled r; or if it comes from a tendency that stammering people have to make sounds like that.

Sanskrit, for example, has the adjective "barbaras", meaning stammering or blithering.

OK, I'm taking your comment stream even further off topic here ... :)
