It's possible you're referring to one of the following:
* A person's name: "Baillie" could be a surname or a given name. In this case, there's no specific language associated with the name.
* A place name: "Baillie" could refer to a town, village, or region. If that's the case, the language spoken in that place would be the relevant one.
* A misspelling: Perhaps you meant to write a different word, like "Bally" or "Balle," which might be associated with a particular language or dialect.
To help me understand what you're asking, could you please provide more context? For example:
* Is Baillie a name? If so, is it a first name or a last name?
* Is Baillie a place? If so, where is it located?
* Did you mean to spell a different word?
Once I have more information, I can help you understand the language you're interested in.
