Here's why it's likely a misunderstanding:
* "Put" is a verb in English. It means to place or position something.
* "Thai" is an adjective or noun related to Thailand. It could refer to the country, the people, the language, or Thai cuisine.
It's possible you've encountered a misheard phrase or a typo.
If you could provide more context about where you heard "put Thai," I might be able to help decipher the meaning.
