köken: From Proto-Finnic *huima (compare Estonian uim, Ingrian huima), probably borrowed from Proto-Germanic [Term?] (compare Old Norse svíma (“to faint, to swoon”)) or Proto-Norse [Term?] (compare Old Norse hvima (“to be confused”)); for sense, compare huimata. Alternatively, possibly akin to huikea (compare tuikea ~ tuima, julkea ~ julma), but in any case influenced by it in terms of meaning.
