There are four main Thai languages spoken in Thailand (Central Thai, Southern Thai, Northeastern Thai (the same language is used in Laos) and Northern Thai, but the language refered to as Standard Thai is close to Central Thai. Being in Bangkok you might notice that Bangkokians skip the "r" in words like the polite ending "khrap".
Learning Thai as a "farang" is not really easy, but the Thai people really appreciate if you make an effort. If you want to learn basic words and sentences buy a Thai language course which is available in every book shop selling English language books.
Thai is a very complicated language to learn with a unique alphabet to make it even more difficult. To master a few words is not difficult however and will be greatly appreciated by the locals.
