While the official Thai language is widely spoken throughout Thailand, many Thais also speak and understand English, though more so in Bangkok and the major tourist areas. However, English is typically the common currency for cross-cultural conversation as Thailand hosts visitors from around the world. 
 
Thai: The National Language
As you might already know, ‘Thai,’ is the most spoken language in Thailand. However, we can find many dialects across the country. These are the 4 most important dialects that you will come across in Thailand.
 
The Dialects
1. Central Thai. Thai language is also known as Central Thai. This is the primary dialect used in education and the media, and therefore, the official language of the country. It is spoken by people in Central Thai and most of the Thai Chinese. From the 60 languages in Thailand, this is the most spoken across the country.
2. Isaan. This name represents all the dialects of the Lao language. It is one of the more well-known dialects spoken in the North-eastern region. 
3. Southern Thai. People in the South of Thailand speak the Southern Thai dialect. 
4. Northern Thai. This dialect is spoken in the North of Thailand. 
Central Thai and the rest of the dialects have many differences but are mutually intelligible for the most part. Also, even smaller groups speak some variations of the Thai language. However, these are nowhere near as widespread around the country.
