The dictionary for Central and E-Saan varieties of Thai is designed as a reference for use by Peace Corps volunteers assigned to northeastern Thailand. An introductory section gives an overview of the dictionary's content and design. Most of the words included are functional vocabulary, and the usage is illustrated in sample sentences written in Central Thai script. Notes are also provided on some characteristics of the phonology, particularly tone patterns and vowels. Contents of the dictionary are entirely in Thai. (MSE)
