Definition

Meaning

A term for money (slang, informal); the title of a tribute paid to an overlord in Southeast Asian history.

As modern slang, it can refer to money, especially a large sum. Historically, it refers to a form of tribute or feudal levy in regions like Siam and Burma.

Linguistics

Semantic Notes

The money sense is likely derived from 'bye' (goodbye to your money) or is rhyming slang. The historical sense is a direct borrowing from Southeast Asian languages.
