Mednyj Aleut language
Mednyj Aleut (also called Copper Island Creole or Copper Island Aleut) is an extinct mixed language spoken on Bering Island. Mednyj Aleut is characterized by a blending of Russian and Aleut (primarily Attu) elements in most components of the grammar, but most profoundly in the verbal morphology. The Aleut component comprises the majority of the vocabulary, all the derivational morphology, part of the simple sentence syntax, nominal inflection and certain other grammatical means. The Russian components comprise verbal inflection, negation, infinitive forms, part of the simple sentence syntax and all of the compound sentence syntax. History. Originally , the language was spoken by Alaskan Creoles on Copper Island, from where it takes its name. The Alaskan Creoles are the descendants of "promyshlenniki" men employed by the Russian-American Company (RAC) and Aleut and Alutiiq women, and formed a small but influential population in Russian Alaska. They were bilingual in Russian and Aleut, and were defined as a high-status special social group by the RAC. Due to increased contact with the Russian language in the 1940s, the majority of the population switched to using Russian instead of Mednyj Aleut. In 1970, the entire population of Medny Island was  moved to Bering Island. In 1994, it was noted that only 15 native speakers were left: in 2021, the last native speaker, Vera Timoshenko, died at the age of 93. Phonology. Consonants. Mednyj Aleut's consonant inventory mostly consists of phonemes shared between Aleut and Russian. The aspirated sonorants /m/, /n/, /l/ and /j/, and the uvulars /χ/ and /ʁ/, come from Aleut and do not exist in Russian, while the labials, stops /p/ and /b/, and fricatives /f/ and /v/ come from Russian and do not exist in Aleut. Labials are mostly used in words of Russian origin, while  aspirated sonorants are used only in native Aleut words. Vowels. The vowel inventory of Mednyj Aleut contains three pairs of vowels from Aleut (/i/, /u/, /a/) and two pairs, /o/ and /e/, from Russian. Vowel length is preserved in Aleut loanwords, and vowels are also lengthened in the verbal inflectional endings borrowed from Russian. Syntax. Mednyj Aleut has a heavily Russian-influenced syntax. In particular, it has a relatively free word order in comparison to Aleut, which is strictly SOV. However, when the direct object in a sentence is a personal pronoun or when an adjunct in a sentence is  an Aleut word, SOV word order is used. For example: Russian complementizers, conjunctions and many wh-words are also used: Additionally, negation is similar to Russian: the Russian prefix "ni-" is used as the negative suffix and the phrase "netu"/"nitu(ka)" ('there is no') is used as a special negative existential construction. Like Russian, Mednyj Aleut does not use copulas in the present tense. The verb 'to be' is the Aleut word 'u-', but Russian verbal inflections are used for it. For example, 'uu-it' means 'is' and 'uu-l-i' means 'were'. The copula is only used in past tense  when the predicate is nominal. When the predicate is adjectival, the predicate is inflected for the past tense like a verb is. Morphology. Nouns. The derivational and inflectional morphology of nouns in Mednyj Aleut comes from Aleut. Notably, Mednyj Aleut contains morphological categories that do not exist in Russian, such as duality. 61.5% of nouns in Mednyj Aleut are of Aleut origin, with the rest coming from Russian. Verbs. The finite, infinitive and the majority of the nonfinite forms of verbs is of Russian origin while the nominal inflectional morphology is of Aleut origin. For example, this table compares selected  finite verb forms for the verb 'to work' between the Bering Island dialect of Aleut, Mednyj Aleut and Russian. The Russian-origin influences are added to the verb stem, which is of Aleut origin. 94% of verbs in the Mednyj Aleut lexicon are of Aleut origin, with a minority coming from Russian. Mednyj Aleut is characterized as considerably more agglutinative than Russian, which is generally considered fusional.
