Positive emotions are regarded as vital constructs in L2 learning. With the advent of positive psychology in SLA, the link between L2 grit and Foreign Language Enjoyment (FLE), as an achievement emotion, has drawn the attention of numerous scholars. However, despite these investigations, what remains is to see to what extent this link can be accounted for by the control and value appraisals of classroom activities and tasks. In other words, what is the matter of debate is how L2 learners’ perseverance and consistency of interest during the performance of language tasks and activities can predict their enjoyment when they are in control of, or out of control of these activities and tasks. Given this gap, this conceptual study attempts to argue the need for the investigation of L2 grit and FLE in light of control-value theory (CVT) and its methodological orientation. These arguments can pave the way for future research on this link via the CVT framework and provide pedagogical and methodological implications for investigators, learners, teachers, teacher educators, educational policy-makers, and advisors to raise their awareness of how the proximal determinants of enjoyment in learning a foreign language can be realized in terms of their perseverance of effort and consistency of interest in achievement activities.
