Communicating accurately and fluently is certainly the ultimate objective of any foreign language learner. Yet, with limited knowledge and inadequate communication skills EFL learners are likely to experience communication breakdowns which are most of the times the outcome of lexical gaps. With this in mind, learners are in need of some strategies that will enable them to interact accurately and assist them in overcoming communication difficulties. Communication strategies are, in fact, crucial in helping EFL learners to communicate successfully especially when encountering speech production breakdowns. The present study investigates oral communication strategies, focusing primarily on its function in adjusting lexical gaps instances in Moroccan high school EFL learners' interlanguage.
