köken: Borrowed from Low German Köter, from Middle Low German kȫter. Standard use since the 18th century. Further origin uncertain. Perhaps imitative of panting.
köken: murtaa (“to break (into pieces)”) + -e. First attested in 1644 in the sense “break, breakage, breaking point”. In 1819, Jaakko Juteini used the word to refer to a nonstandard usage of language; one year later, in 1820, Finnish linguist and author Reinhold von Becker became the first to use it to mean “dialect”.
