köken: Of unknown origin. Note resemblance to (and more discussion at) White Hmong te (“frost”), though the vast time depth required for a relation (i.e. when the pre-Uralic tribes were still in China), relative simplicity of the word structure, and absence in other Uralic languages (assuming the word existed in Proto-Uralic) makes a connection highly speculative.
