I want to know the answer to the following question:
Where does the name theravada come from?
All the background I'm provided with is that "After unsuccessfully trying to modify the Vinaya, a small group of "elderly members", i.e. sthaviras, broke away from the majority Mahāsāṃghika during the Second Buddhist council, giving rise to the Sthavira sect.". Is that enough to answer the question?
Answer: no
