I'll be writing a paper in the coming months in order to satisfy my IB requirements.

My focus is, "How did the Indo-Aryan Migrations influence the present similarities between English and Hindi?" I have to focus on the historical aspect rather than the linguistic aspect. I plan to show the progression from Proto-Indo-European as the culture and linguistic properties diverge southward and westward.

The structure will be something like:

Proto-Indo-European --> Germanic --> Western Germanic --> English
Proto-Indo-European --> (Possibly Another) --> Sanskrit --> Hindi

I'm working on accumulating sources at this point. I have several relating to linguistics but few like "History of Germanic Culture", etc. If any of you are experts in this field (which would be surprising) or know of any good history books I would appreciate a little help.
