It is pronounced Nukmuai Thai. Not mui thai.
Westerners misunderstood the correct annunciation and have been saying it incorrectly for years. The Thai people never bother to correct westerners because they don't fully understand english. Thai people will agree and shake their heads in agreement because they can't be bothered to correct anything alot of times.The city is not called Bangkok. It is known in Thai as "Krung Thep Mahanakorn" but they can't be bothered to ever correct foreigners on that either for years. It's lack of caring and not wanting to be bothered to correct tourist, not fully understanding English, and lack of education that the sport has been pronounced wrong for years. It's counter productive to work so hard and be so dedicated to learn the sport yet don't know how to say the name of the sport correctly. It shows lack of true knowledge. It's not the westerners fault because nobody bothered to tell them properly. So I am trying to clear up the confusion because I am Thai. Most of your Thai mentors will not bother to correct you either because some of them don't want to admit that they have told you something incorrectly.To see so called Thai boxing professionals not even know how to pronounce the sport correctly really shows lack of true expertise and professionalism. Ignorance is sad.
http://www.tattoo.fgh.com.sg/Australian_MuiThaiTrainers.html These ignorant Australians didn't even realize that they were not getting a traditional Thai tattoo from a Thai person who are actually of Malayan ancestry. Instead they went to a chinese guy that learned to do traditional Thai tattoo. The Chinese guys name is Lao and his tatoo shop is called FO GUANG HANG. How stupid can you be to not know that you are not being tattooed by a traditional Thai tattooist who have f Malayan features. It's like going to an Australian food restaurant that's own by Chinese and all the cooks making the Australian food are Chinese. Ignorance is sad.
