Hello Dipo,
That is an old post and I just revised it since it could be misleading:
“A Buddhist or a Bhauddhayā?”
The Pali word for a Buddhist is “Upāsaka” and the Sinhala word is Bhauddhayā. It is just interesting that the Sinhala word provides a better-embedded meaning.
– Thanks for asking about it. It needed that clarification.
