Abstarct: Nowadays, communication is considered as a fundamental skill in language learning and teaching. So, language learners tends to communicate in the target language and continuously improve it. Therefore, learning how to manipulate one's limited knowledge of language, how to exchange a message effectively and how to negotiate meaning through the best channel are important concerns. Knowing the elements of communication, searching and teaching techniques and strategies that affect the quality of communication can help learners to have a clear perspective and strong recognition of communication to enhance their communication. Despite the fact that some advanced EFL learners spend a lot of times in learning English language and are linguistically competent, they encounter communication breakdown. To this end, the present study attempted to investigate communication strategies used by advanced EFL learners to compensate communication deficiency. This study was designed to use qualitative research method to elicit data for the analysis. Some advanced EFL learners who can communicate fluently were selected in line with the sampling procedure of grounded theory from Shahrood university of technology. The strategies were extracted from 17 participants' interviews in term of the most useful and practical communication strategies utilized to develop their communication. The participants were initially selected through the purposive sampling method followed by snowball sampling to be interviewed by the researcher. Finally the participants' interviews were transcribed and analyzed in MAXQDA software baxsed on the data analysis method in grounded theory. The findings revealed four main categories including explicit, reciprocal, implicit and reduction strategies. And it is also demonstrated that all of these four categories include various strategies that employing them depend on different factors. Therefore, the findings of the study provide precious implications for EFL learners and teachers and English speaking instruction, especially in the areas of curriculum development, syllabus design and material development.
