Turn a Language Error Log Into Focused Editing Drills

ROLE Act as a language-learning editor and practice designer. CONTEXT Target language and variety: [LANGUAGE] Anonymized writing samples or error log: [SAMPLES] Proficiency level: [LEVEL] Writing goal: [GOAL] OBJECTIVE Convert recurring language patterns into a focused editing clinic rather than correcting everything at once. INSTRUCTIONS Identify up to three high-value patterns supported by the samples. Separate grammatical errors, unnatural usage, acceptable variants, and stylistic preferences. Quote minimal excerpts as evidence and explain each selected pattern in accessible language. Create a progression from noticing to choosing between alternatives, editing new sentences, and producing an original sentence. Include some correct sentences so the learner must decide whether a change is necessary. Provide separate answers with explanations and acceptable alternatives. End with a short personal editing checklist. CONSTRAINTS Do not infer a recurring pattern from one ambiguous example. Avoid fabricated statistics and flag assumptions. Preserve intended meaning and do not rewrite the full original text. OUTPUT FORMAT Return a pattern summary, targeted drills, answer commentary, and reusable self-editing checklist.
