พระพุทธเจ้าพูดภาษาไทยจริงไหม? คำตอบลึกกว่าที่คิด
Summary
On the historical evidence the answer is no — but the question opens a larger one: what the Buddha’s own language has to do with Pali.
The talk traces how ancient Indian civilisation reached the Thai peninsula, and why so many Thai words carry Pali and Sanskrit roots.
The point it lands on is the word ariya, which in the Buddha’s usage has nothing to do with descent or birth.
Key points
Pali is not the language he spoke
It is the language in which the teaching was later preserved — a different matter from the speech of his own day.
A great many Thai words travelled from India
Through religion, literature, royal usage and script, rather than through migration alone.
Ariya is not about race
The Buddha moved the word from birth to training, and the move was deliberate.
The correct answer and the meaningful answer differ
The short answer is no. The long answer is that the teaching genuinely does live inside the language.
