This dictionary is geared toward those who are working, traveling or doing business in Southeast Asia, and are already learning to speak Thai, Malay, or Vietnamese. It is meant to serve as a ready reference as one moves about in and through Thailand, Malaysia and Vietnam. One may find as one travels in these countries that the natives rarely know much of their neighbors' languages; so it seems prudent to be prepared for this "gap". Of course, a dictionary can't teach a person to speak a language, but in conjunction with a good language course, it is hoped that this dictionary will be useful.
