The equivalent translation of English-Thai-Lao-Vietnamese words in the 1st Order Entity was examined by bi-directional translation method using the native speakers of English, Thai, Lao, and Vietnamese as the key informants. They were asked to translate from source language to target languages and then from target to source language; for example, from English to Thai and from Thai to English.
