The study attempts to display whether UPKAN (Université Pédagogique de Kananga) students use properly the intonation in different questions or they are rather frequently substituted by alternative patterns. It has a stab at showing the circumstances behind this suprasegmental feature fossilization, and hence suggests strategies to be used in order to de-fossilize and/or to prevent the occurrence of these fossilized suprasegmental errors. The primary goal of this study is to determine the main areas of difficulty in the performance of English intonation of different kinds of questions by UPKAN EFL students, that is, to analyze the errors these subjects make and hence offer suggestions that may be helpful in reducing questions intonation among EFL learners.
