Reconstruction:Proto-Finnic/kiukasa

Etymology
, with the first part being shortened. Most descendants shorten the second part as well, turning the word into an *-as-stem (either with or without consonant gradation of *-k-), in eastern varieties further generalized into an unalternating aa-stem.

Many sources assert instead as the original second element, but Ylikoski (2016) argues that this does not match almost any of the descendants, and shows that no detailed argument for this reconstruction has ever been given. Pahomov (2017) on the contrary insists that some eastern Finnic words, such as and, do descend from this via regular metathesis, through the development *kiukuδa > *kivikota.

Noun

 * 1) stove in a sauna
