Understanding how a student's first language (L1) influences their English learning is one of the most powerful tools in a teacher's arsenal. Contrastive analysis compares L1 and L2 structures to predict and explain common errors.
| L1 | Common English Errors | Cause |
|---|---|---|
| Spanish | Adjective after noun ("car red") | Different word order in Spanish |
| Japanese | No articles ("I went to school") | No article system in Japanese |
| Arabic | Verb before subject ("Went he") | VSO word order in Arabic |
| Polish | Missing articles, tense confusion | No articles, aspect-based system |
| Chinese | No plural markers, tense confusion | No inflection in Chinese |
Not all L1 influence is negative. Cognates (similar words), shared grammar patterns, and cultural knowledge can accelerate learning. Spanish speakers benefit from Latin-based vocabulary; German speakers share word order patterns.
Strategic L1 use can be helpful for contrastive explanations, especially at lower levels. Brief L1 comparisons save time and build understanding. But keep the class primarily in English — L1 should support, not replace, English use.
