Learners can overcome language learning plateaus by setting new challenges, changing learning methods, seeking feedback, practicing regularly, and staying motivated. Setting new challenges provides a fresh focus and direction for learning, while changing learning methods prevents stagnation and boredom. Seeking feedback from peers or language tutors helps identify areas for improvement, and practicing regularly maintains progress and skill retention. Finally, staying motivated through goal-setting, rewards, and reminders of the benefits of language proficiency encourages persistence and resilience in overcoming plateaus.
