Oxford-RiverBooks Thai (InApp) is the in-app purchase edition of the Oxford-River Books Concise English–Thai Dictionary. The app is free to download, and owners of the earlier paid Oxford Riverbooks Thai Dictionary app can use it without paying again; new users activate the dictionary with an in-app purchase.
The dictionary is the result of more than 18 years of work by Oxford University Press together with the Chulalongkorn University translation and interpreting centre in Bangkok. It brings together more than 230,000 English and Thai words and phrases, with guidance on useful phrases and the three forms of English verbs, making it a gateway to English for Thai speakers in every field.
The app offers the same features as the standard edition, including search from English or Thai, real-time results, wildcard, and three-way cross-referencing search, and the complete appendices and introductory material. Previous owners who have trouble opening the dictionary are invited to contact Enfour.
