See, I'm actually OK with it being Hindi. Its the language of the Gods, yeah. So for those of us who play Skyrim, so were the Tha'um. Being fluent in the Dragon Language was lost or entirely unknown. But one or two words... quite possible they would have survived. And have power, at that... of course, I assume part of the essence of the unicorn horn was used up doing that little teleporting trick. Anywho, I vote Yes to the him using the Hindi, but maybe keep it shorter.

Oh! Okay then... I guess I can edit something back in, and yes you were correct on the essence part of the spell, the horn will have basically been reduced to dust when he reaches the other end due to using up all of its power in the jump.
