I want to know the answer to the following question:
What is the term for someone who has achieved nirvana?
All the background I'm provided with is that "Nirvana (Sanskrit; Pali: "Nibbāna") means "cessation", "extinction" (of craving and ignorance and therefore suffering and the cycle of involuntary rebirths (saṃsāra)), "extinguished", "quieted", "calmed"; it is also known as "Awakening" or "Enlightenment" in the West.". Is that enough to answer the question?
Answer: no
