(A) instances of negative evidence
(B) intra-lingual errors
(C) global errors
(D) formulaic chunk

Intra-lingual errors are mistakes that occur in language learning due to issues within the target language itself, rather than being caused by interference from the learner's native language (which would be inter-lingual errors). These errors often arise as learners try to generalize or apply the rules of the target language but do so incorrectly.

Key Features of Intra-lingual Errors:

1. Overgeneralization: Applying a rule too broadly to situations where it does not apply.

   • Example: goed instead of went because the learner overgeneralizes the regular past tense rule (-ed).

2. Ignorance of Rule Restrictions: Failing to recognize the limits of a rule.

   • Example: She explained me the problem instead of She explained the problem to me.

3. Incomplete Application of Rules: Using a rule partially or improperly.

   • Example: He going to school instead of He is going to school.

4. False Concepts Hypothesized: Misunderstanding the rules or their application.

   • Example: Using is in He is liked apples because the learner mistakenly thinks the verb "to be" is required in all sentences.
