Kyakhta Russian–Chinese Pidgin was a contact language used by Russian and Chinese traders to communicate during the 18th-early 20th century. The pidgin owes its name to the town of Kyakhta, a Russian town on the border with the Qing Empire's Outer Mongolia, which was the most important border trading point between the two regions for more than a century after its foundation in 1728. In Russian it is known as Кяхтинский язык and in Chinese it is known as 中俄混合語.
Phonology
Due to the absence of consonant clusters in Chinese and their quite frequent occurrence in Russian, the need for epenthesis - adding additional sounds to words - arises to make pronunciation easier. Thus, the following transformations are typical:
Most of the words in the Kyakhta pidgin come from Russian. Many of them, in particular those that do not have consonants clusters, undergo no change; for example, , , , , , , , . As a rule, pidgins have limited grammar and vocabulary. To compensate for this, words are often borrowed with additional meanings. In Kyakhta pidgin, for instance, the adverb, along with the meaning of "little" that it has in Russian, also means "not only"; means not only "to seat", but also "to converse". An example of significant difference between the Russian translation and the meaning in Kyakhta pidgin is the wordмесяца - it means "months" in Russian, while it means "forever" in the pidgin. The predominantly colloquial origin of words is very noticeable. Many words are present in exclusively diminutive form: женушеки comes from Russian женушка, the diminutive form of ; рюмашека comes from Russian рюмашка, the diminutive form of ; беленеки comes from Russian беленький, the diminutive form of. While Russian is clearly the main source of vocabulary, some words are borrowed from Mongolian which was spoken in the same region, such as адали, and бичиху. Still, the influence of Mongolian is minimal. The only significant contribution of Chinese to the vocabulary is the word фуза meaning "store, shop". Aside from that, Kyakhta pidgin contains several new compounds that could have been inspired by Chinese:
ума-конейчайло can be loosely translated to Russian as end-of-mind, it was used instead of Russian сумашествие
середеце-шило instead of Russian жестокосердие
языка-меда instead of Russian .
Morphology
Like most pidgins Kyakhta pidgin lacks many morphological categories - there are no cases, numbers or gender of nouns. Russian pidgins in general tend to have clear verb indications. In Kyakhta Pidgin, similarly to other Siberian pidgins, most verbs have ending -j/-i: болей, выгони, захорони, гоняй, незнай, ругай, сади. This ending makes verbs similar to the imperative form of Russian verbs: for example, болей is the Russian verb , but in the imperative mood. We can speculate that such forms prevailed when Russians addressed their interlocutors. During the late stages of the pidgin, the indicators of verb tenses appear: было indicates the past tense, буду indicates the future tense, еса indicates the present tense; for example, погули было means "to have walked", погули еса means "to be walking", погули буду means "will walk". An object is identified with за - a preposition from the Russian language that has many semantic properties. It is the only preposition present in the Kyakhta pidgin and it is used in the following way: за наша походи means "come to us", за наша фуза means "in our store". Russian pronouns came into the pidgin in an exclusively possessive form: моя means "mine" in Russian, твоя means "yours" in Russian, and ево comes from Russian его, which means "his" in Russian. This feature is shared with the Norwegian-Russian pidgin Russenorsk. All declensions of pronouns are formed with the already mentioned за: за-моя, за-твоя, за-ево.
