Kahekeelne

Kahekeelne is a term used in linguistics to describe a proposed mode of language production in multilingual settings in which two language systems converge to form a shared grammatical framework, rather than simply alternating between separate codes. The word is sometimes traced to roots meaning “two languages” (from the Estonian kahe- ‘two’ and keel ‘language’) with the suffix -ne forming an attributive adjective. In scholarly discussions, kahekeelne is treated as a potential intermediate or emergent state in language contact, distinct from straightforward code-switching or from fully formed bilingual grammars.

Key features attributed to kahekeelne include the coexistence of two linguistic repertoires within a single utterance or discourse segment, partial convergence of morphosyntactic patterns across the two languages, and the emergence of shared grammatical conventions that operate across both codes. Speakers may retain core vocabularies from each language while adopting a unified set of inflectional or syntactic rules in particular domains, such as tense, agreement, or word order. Contexts of social meaning, identity, and community norms are considered important influences on how and when kahekeelne patterns become stable.

The status of kahekeelne in current theory is debated. Some researchers view it as a theoretical construct for describing certain emergent bilingual practices, while others see it as overlapping with or transitional to creole formation or advanced code-mixing. Empirical validation relies on longitudinal sociolinguistic data and careful cross-language analysis.

Example: a bilingual speaker might produce, in a single clause, a predominantly Estonian structure with insertions of English vocabulary and a shared, simplified inflectional pattern across both languages.
