Chaplino Eskimo (ISO 639-3: ess) is a code name for one of Eskimo languages of the Yupik group (Eskimo-Aleut family of languages). Other language names include: Asian Eskimo language, Eskimo, Asian Eskimo, Yupik, Yuit; American researchers talk about (Central) Siberian Yupik.
The name of Chaplino language can be misleading, since its former and current speakers inhabit not only Novoe Chaplino, but also other settlements, including the ones on St. Lawrence Island (USA). Asian Eskimo Language (AEL) is also not a good fit, since it includes not only Chaplino, but also other Asian Eskimo languages, and excludes the language of. St Lawrence Island.
The number of Chaplino speakers is rapidly decreasing. While in the mid-1960s, about 200 out of approximately 1 200 Chaplino Eskimos were fluent in their native language (Vakhtin 2001), by 2020, there remained only a few speakers. Based on the data provided by Daria Morgunova (2020), Novoe Chaplino is one of two places in Chukotka where one might still hear people speaking Eskimo (the second one is Sireniki). There are only few fluent Chaplino speakers left in the village, and they are all from the older generation. There are also several women aged between 40 and 50 that are capable of speaking and understanding the language. Nonetheless, local population still uses Chaplino in some communicative situations: certain words and even expressions are regularly used in everyday conversations. That includes jokes, short tales, lullabies, standard expressions that sometimes slip even in conversations of younger people, although they are convinced that they speak only Russian. Switching from Russian to Chaplin and back and code-mixing is a standard practice for many of them.
