When visiting a foreign country it is always a good idea to learn some words. You probably won't need to use much if you stick to the main tourist destinations. However, the Thai people you encounter will be impressed for sure if you try and use a little Thai with them. Before you start, I need to warn you that Thai is a tonal language so unless you "sing" the word in exactly the right way you probably won't be understood. That is why learning Thai from a phrase book and some web sites is a waste of time. Throughout this web site you will be able to listen to me speaking Thai. You will also see a pronunciation guide using Roman letters. If you are serious about learning Thai then please take the time to learn to Read Thai.
