Interlanguage

language culture Maturity 11-13 Next article →

An interlanguage is a unique linguistic system. It is developed by people learning a second language (L2). This system is an idiolect, which means it is a way of speaking unique to one person. It is not exactly the learner's first language (L1). It is also not exactly the target second language. Instead, it exists in the space between them. This system preserves some features of the L1. It also uses rules from the L2 in new ways. Sometimes, learners overgeneralize rules. This means they apply a rule to places where it does not belong. This creates a distinct linguistic organization.

Several factors shape how an interlanguage works. One major factor is L1 transfer. This happens when a learner uses rules from their native language. Other factors include previous learning strategies and L2 acquisition strategies. Communication strategies also play a role. A learner might use specific methods to get a point across. The way a learner uses the L2 can also change based on context. For example, they might be more accurate in a classroom. They might be less fluent in a fast conversation. This shows that interlanguage is highly variable.

Interlanguage can show different types of variation. One type is free variation. This occurs when a learner has not fully mastered a rule. They are still deciding which forms to use. Another type is systematic variation. This is caused by changes in social or linguistic contexts. For instance, a learner might change their speech based on who they are talking to. This is known as communication accommodation theory. A learner might change their style to match or differ from another person. They might even use a non-target form to show their identity. Linguistic factors also cause systematic variation. A learner might be more accurate if a word follows a vowel. They might be less accurate if it follows a consonant.

History shows how our understanding of language has changed. Before the 1970s, researchers used contrastive analysis. This method assumed all errors came from L1 and L2 differences. It focused on deficits and treated errors as random mistakes. In 1957, Robert Lado suggested this needed more systematic data. Later, research shifted toward error analysis. Researchers found that L1 transfer could not explain everything. Several scholars worked on these ideas independently. William Nemser called it an "approximative system." Pit Corder called it "transitional competence." In 1972, Larry Selinker introduced the term "interlanguage." He also coined the term "fossilization." His work was based on research by Uriel Weinreich.

Learners often go through specific developmental stages. One method involves using "prefabricated patterns" or "chunks." These are groups of words treated as a single unit. For example, a learner might hear "do you" as one sound. They might say "What do you doing?" instead of "What are you doing?" Eventually, they learn to break these chunks apart. Learners also sometimes show a U-shaped learning pattern. This looks like a regression in skill. A group of learners might use a rule correctly at first. Then, they start using it incorrectly. Finally, they return to using it correctly. This happens because they are learning deeper grammar rules. Their new knowledge disrupts their old habits.

Sometimes, an interlanguage stops growing. This process is called fossilization. It is the final stage of interlanguage development. It can happen at any stage of learning. Even motivated learners can experience fossilization. It can happen due to complacency or specific obstacles. Many adult learners experience this. It often occurs when a learner can communicate well enough. If they can share their meaning, they may stop correcting their form. This means the transition between L1 and L2 freezes.

Interlanguage is connected to larger linguistic ideas. It relates to the concept of Universal Grammar (UG). This is a theory about how the human brain handles language. Research suggests interlanguage conforms to these universal norms. However, interlanguage UG is different from native UG. It varies based on a learner's L1 and specific constraints. One example is an island constraint. This is a rule about where certain words can go in a question. Interlanguage is also related to pidgins and creoles. These are also unique languages. However, interlanguage is personal and changes as the learner improves. Pidgins and creoles are often more stable and belong to groups.
