IPA: /ˈɪn.təˌlæŋ.ɡwɪdʒ/

Definition:

Interlanguage refers to a linguistic system that develops when a person is learning a second language (L2). It combines elements from the learner’s native language (L1) and the target language, often containing unique rules and forms that do not belong fully to either language. This system evolves as the learner progresses, gradually approximating the target language.

Key Characteristics:

1. Dynamic and Transitional:
   • The interlanguage system is not static; it evolves as learners gain proficiency. Errors often reflect the current stage of learning.
2. Influence of L1:
   • The learner’s native language heavily influences interlanguage, leading to transfer errors (e.g., direct translation of idioms).
3. Fossilization:
   • Some interlanguage forms may become fixed and persist even in advanced stages of learning.
4. Systematic yet Unique:
   • Interlanguage follows its own internal rules, which may be logical within the learner’s understanding, even if they differ from standard L2 grammar.

Examples:

• A Spanish speaker learning English might say:
  • “He have a car” (incorrect verb conjugation influenced by Spanish grammar).
• A French speaker learning English might not omit articles:
  • “I go to the school” (influence from French where articles can sometimes be omitted).

---

Etymology:

Coined in the 1970s, the term combines inter- (meaning “between”) and language, reflecting its role as a transitional state between two linguistic systems. It was popularized by linguists such as Larry Selinker, who studied second language acquisition processes.

Role in Second Language Acquisition (SLA):

1. Error Analysis:
   • Mistakes made by learners reveal how their interlanguage system is structured.
2. Developmental Sequences:
   • Learners pass through predictable stages in acquiring certain grammatical structures (e.g., negation, question formation).
3. Communication Strategies:
   • Learners may rely on strategies like code-switching or approximation to fill gaps in their L2 knowledge.

Interlanguage Theories:

1. Selinker’s Five Central Processes:
   • Language Transfer: Influence from L1.
   • Transfer of Training: Influence from how the language is taught.
   • Strategies of L2 Learning: Methods learners use to internalize the language.
   • Strategies of L2 Communication: How learners compensate for gaps in knowledge.
   • Overgeneralization: Applying L2 rules too broadly (e.g., comed instead of came).
2. Krashen’s Input Hypothesis:
   • Suggests that learners acquire language best when exposed to comprehensible input slightly above their current level of interlanguage.

Synonyms:

• Transitional Language
• Learner Language
• Intermediate Language

Related Terms:

• Fossilization: The process by which incorrect interlanguage forms become permanent.
• Code-Switching: Alternating between L1 and L2 during communication.
• Pidgin: A simplified form of language that develops between speakers of different native languages, though not transitional in nature like interlanguage.

Examples in Context:

1. Linguistic Research:
   • “Her interlanguage revealed a consistent overuse of the present progressive, which aligned with common patterns seen in Spanish-speaking learners of English.”
2. Everyday Learning:
   • “During the early stages of language learning, many students develop an interlanguage that includes phrases like ‘She no go yesterday.’”
3. Language Teaching:
   • “Teachers should understand interlanguage to provide feedback that guides students toward accurate L2 usage without discouraging their progress.”

Importance in Linguistics and Education:

• Understanding Learning Processes:
  • Studying interlanguage helps educators and linguists identify patterns and common challenges in second language acquisition.
• Error Correction:
  • Recognizing the interlanguage stage can guide instructors in offering constructive feedback.
• Personalization:
  • Tailoring instruction to the learner’s interlanguage fosters more efficient and empathetic language teaching.

Takeaway:

Interlanguage is a crucial concept in second language acquisition, reflecting the learner’s ongoing journey toward fluency. It is a dynamic, rule-governed system that bridges the gap between native and target languages, highlighting the complexity and individuality of the learning process.
