Which learner is most at risk of fossilization?

1. Fossilization freezes an interlanguage at some stage. 2. It can occur even in motivated learners who are continuously exposed to the language. 3. It often occurs in adults who succeed in conveying messages with their current proficiency. 4. Without a need to correct form or structure, such a learner stops improving. 5. An anxious and silent learner produces little language, so there is little to freeze. 6. So the learner whose errors never block meaning is most at risk. **Why the other options fail:** - An anxious, silent learner has too little output to fossilize. - Frequent correction pushes a learner to change forms, so it works against fossilization. - Wide reading brings new input and keeps the interlanguage growing. _Source: Wikipedia, "Interlanguage", section "Fossilization" (revision 1370333900)_
