The notion of World Englishes which is now being increasingly recognized by most linguists and scholars has stimulated the search for a new linguistic model that can accommodate and facilitate the use of English as a lingua franca. On the other hand, the paradigm of World Englishes also necessitates recognition of various Englishes from different parts of the world. ln Indonesia, more teachers are starting to understand that todays English language instruction is no longer aimed at merely imitating foreign varieties, such as American English, British English. and Australian English. However, they are faced with a dilemma because it means that they might need to give up the long-established prescription for American, British. or Australian English as the only desired language model. The lack of clarity regarding which variety should be used as a model for English language teaching in Indonesia is what underlies the writing of this book. lt is an attempt to identify and describe the linguistic features of Indonesian English in the hope of foreseeing any functional version of the variety which might become a factor in the plurality of World Englishes. With all its limitations, this book seeks to provide a brief depiction of the linguistics of Indonesian English and discussion about the extent to which this variety may be integrated into the practices of English language teaching in Indonesia. "Unlocking the door to a new era in language instruction, this book is a groundbreaking exploration of the evolving linguistic landscape in Indonesia. As English transforms into a global lingua franca, this book navigates the complexities faced by educators, offering a thoughtful and practical guide to incorporating the distinctive features of Indonesian English. A must-read for anyone shaping the future of English language teaching, this work is a beacon of clarity in a world of linguistic diversity." Assist.
