There are three main types of ELT dictionaries: monolingual, bilingual, and bilingualized. Each type of dictionary, while having its own advantages, also hinders the learning of English as a foreign language and culture in so far as it is written from a homogenizing (linguistic- and culture-centric) perspective. This paper presents a new type of dictionary that tries to overcome the linguistic and cultural limitations of its predecessors. This is achieved by means of a series of strategies that have to do with localization, delocalization, globalization, and glocalization of language and/or culture. It is hoped that the presentation of the linguistic and cultural strategies underlying this new kind of dictionary will: (1) help the ELT community to improve students' linguistic and cultural competencies; (2) help teachers evaluate the efficacy of different ELT dictionaries; and (3) promote the creation of more effective ELT dictionaries.
