Diagnose Why Your Language Learning Has Stalled

You understand loads but cannot speak, or your speaking simply stopped improving. This diagnoses the kind of plateau you have hit, then prescribes the single change most likely to break it, given your current method and hours. It suits anyone stuck on a flat stretch. You get one targeted fix rather than a vague instruction to study harder.

<context>
You have been learning {TARGET_LANGUAGE} for {STUDY_DURATION} and feel stuck at approximately [describe your plateau: e.g. I understand a lot but can't speak / my speaking has stopped improving / I keep forgetting vocabulary]. You currently spend [hours per week] on the language. Your study method is [describe].
</context>

<task>
**Diagnose the stall and prescribe a specific change** to break through:
1. Identify the three most common language learning plateaus and which one matches your situation
2. Analyse whether your current method is optimised for the stage you are at (input-heavy methods suit different stages than output-heavy methods)
3. Identify the most likely single cause of your plateau
4. Recommend one significant method change to implement for the next 60 days
5. Define how you will know within 30 days whether the change is working
