kielivälistä

Kielivälistä is a Finnish term that translates to "interlanguage" in English. It refers to the linguistic system that a learner of a second language develops. This system is not identical to either the learner's native language (first language) or the target language they are learning. Instead, it is a unique, dynamic, and evolving linguistic system that is influenced by various factors.

The formation of kielivälistä is a complex process. It is shaped by the learner's prior linguistic knowledge, their cognitive abilities, and the input they receive from the target language environment. Learners may draw upon their first language, a process known as transfer, which can lead to both correct usages and errors. Additionally, learners create their own hypotheses about the target language's rules, which may or may not be accurate. This can result in systematic errors, often called interlanguage errors, that are distinct from random mistakes.

The study of kielivälistä is a significant area within second language acquisition research. By examining learners' interlanguage, researchers aim to understand how language learning occurs, identify common learning patterns, and develop more effective teaching methodologies. The concept acknowledges that learners are not simply passive recipients of new linguistic information but active constructors of their own linguistic systems as they progress towards proficiency in a second language.
