tadbhava
A word inherited from Old Indo-Aryan through a Prakrit used in a modern Indo-Aryan language.
However, beyond lexis, the Macmillan range includes other adaptations, such as IPA encoding which reflects Indian English pronunciation, and etymologies that distinguish between "tatsama" and "tadbhava" terms, based on McGregor (1992).
