sure I heard the term "indoeuropean", but I'm not sure if it really means the same as "indogermanic"...
I don't know about links between latin and sanskrit, but I know that there are links between old german, kurdish and sanskrit in details e.g. in grammar, that seriously differ from the use in any romanic language like italian, spanish, and further derivated like french and english.
... but after all, it does't matter THAT much.
I didn't grade a Linguistic Doctor and I don't want to, so what...

oh... and have a nice day.
