This study presents a microscopic analysis of distributional and syntactical aspects of ۲۱۸۹ research questions (RQs) in ۷۴۸ articles from four leading L۲ research journals published between ۲۰۰۰ and ۲۰۱۹. Concerning distributional features, The Modern Language Journal was found to include the largest number of both RQs and constituent words. Syntactically, there was no significant difference between polar and non-polar RQs. However, RQs were mainly formulated either as simple or complex questions with only a few comprising compound or compound-complex structures. Additionally, a substantial majority of RQs were used in the present tense, with past tense and future being the next frequent tenses. More specifically, it was noted that most of the RQs involved simple present tense wh-questions, insinuating that L۲ researchers opted for more qualitative RQs, lending themselves to more extensive descriptions, explanations, and interpretations. The findings will have several implications for students and instructors of graduate writing courses.
