Thai is a tonal language with five tones, which means the same syllable can mean completely different things depending on how you say it. That sounds intimidating, but in practice most Thais will understand what you mean from context, and any attempt at their language goes down extremely well. Even a mangled "khob khun" beats pointing and hoping. One thing to know first: Thai has polite particles added to the end of sentences. Men say krap (sometimes written krub), women say ka. You can attach either to almost any phrase to make it polite. This guide uses krap/ka to show where the particle goes.
The Golden Rule: Krap and Ka
Add krap (men) or ka (women) to the end of any phrase to make it sound respectful. Locals use it constantly. You should too.

A Few Tips
Thai people are generally very patient with foreign attempts at their language. Smiling helps with everything. If you say something and get a confused look, try saying it slightly differently or writing it down to show a local who can help. The tones matter most for words like mai (which can mean "no", "new", "burn", or "silk" depending on tone), but context usually saves you. The word sanuk means fun, enjoyment, or having a good time. It is a core Thai value. If something is sanuk, it is worth doing. Keep that in mind and you will get along fine.
