About Tatsama
Tatsama are Sanskrit loanwords in modern Indo-Aryan languages like Assamese, Bengali, Marathi, Nepali, Odia, Hindi, Gujarati, and Sinhala and in Dravidian languages like Malayalam and Telugu. They generally belong to a higher and more erudite register than common words, many of which are directly inherited from Old Indo-Aryan (tadbhava). The tatsama register can be compared to the use of loan words of Greek or Latin origin in English.
