Questioning is known to have been used to probe the validity of an assumption, analyse the logic of an argument, and explore the unknown. Instead of lecturing what is true or false, philosophers utilized questioning for students' understanding of a subject and then leading them to discover logical conclusions. Although role and types of questions utilized by teachers have been investigated in various learning environments, not the same attention has been given to students' questions. This study aims to explore English major students' question formation in the target language and analyse their interrogative constructions in terms of correct question forms and identify the specific difficulties they face while forming questions. In line with this purpose, 30 students were provided with a set of pictures and asked to write down as many questions as they could about these pictures within the time given. The study was conducted with students in the Department of Translation and Interpreting Studies, and the participants were 14 first-year and 16 second-year students. The study also utilised an open-ended questionnaire regarding the difficulties students had while conducting the activity and forming interrogative sentences in English. Students' productions and the data collected from the openended questions were subjected to content analysis. It was found that the students constructed mostly Wh-questions and demonstrated errors in word order and verb form and that they had difficulties in forming interrogative constructions. Results are believed to help educators have a picture of challenges students face in this process.
