Which type of error tends to be systemic because it is repeated across many contexts?

• A. Discourse Errors
• B. Overgeneralizing
• C. Transfer Errors
• D. Systematic Errors

Answer: (D)

Systematic errors are patterns that repeat across many situations because they come from the learner’s internal rule set or from influence of another language. When a student consistently makes the same kind of mistake in different contexts—like omitting articles in English across multiple sentences or applying a grammar rule too broadly—the error isn’t a one-time slip. It reflects how their developing interlanguage is shaping their language use, leading to repeated, predictable mistakes. That persistent, context-spanning nature is what makes this type of error the best fit. Discourse errors focus on organization, overgeneralizing is a specific rule mistake, and transfer errors come from the influence of L1; none capture the pattern of being repeated across many contexts as clearly as systematic errors.
