Coming smack dab off the menu pages from the Tongdang restaurant I mentioned only moments ago is your word for the day. You can read the same story I read about their Thai kitchen by visiting their website. I guess you can call it food for thought.
Learning Thai dot com is a great starting point for some basic Thai words and referrals to additional resources. For a brief history of the language, Thai alphabet, and pronunciation guide go to Omniglot. (A pretty clean and simple site with good details.) Another good source would be the Pimsleur language audio CD’s. I used these to prepare for my trip and they worked great! Before making the purchase look into your local library. There are several libraries carrying these audio CD’s and many more.
Past Thai words: hàat sai, wan sao, sawatdee khrab
