Merging vocabulary is'nt that hard
actually.In fact most Indian languages has shared vocabulary,even those of different language families(Are you even an Indian btw?)
Almost 90% of the vocabulary of Malayalam,a South indian dravidian language comes from sanskrit/indo aryan.
It can be said the same for Telegu and Kannada.(Tamil purged most of its Indo Aryan influence in the 50s)
