One example of pidgin language found in Thailand is known as 'Tinglish.' It's a language that native people use to communicate with foreigners, because 27% of the native people that live in Thailand speak English. 

English is one of the most widely spoken foreign languages in Thailand. It's taught as a second language in Thailand, and it's a language used commonly in the business and tourism sectors. Furthermore, learning English has become increasingly important in the education system. However, depending on the region in Thailand, some Thai people speak more English than in other regions. 

There aren't that many Creole languages in Thailand, but there was Thai Portuguese Creole that was formerly spoken in the Bangkok neighborhood of 'Kudi Chin' by the Thai Catholics of Portuguese decent.
