[Facts] Re: Indian, Sanskrit, and Hinduism names.
I believe this sound loss mainly affected names/words that ended with short vowels, notably the short A (the inherent or default vowel that is generally unwritten). In Hindi and other modern descendants it is now often realized as a schwa when in the middle of words, but as far as I understand, it is also often dropped mid-word. Transcriptions into Latin text might still show it medially as an "a" even when it is not pronounced.
