Commentary
The vowels in Hungarian, Khanty and Mansi point to Proto-Ugric/Proto-Uralic *i, and the word-initial consonants can be regularly derived from *č. The etymology is thus phonologically regular, and a Proto-Ugric word can be assumed.
UEW reconstructs a verbal stem to Proto-Ugric; the verbs in Khanty (DN čĕtimə-) and Mansi (KU šǟtəp- etc.) reflect different derivatives, and the Hungarian adjective sötét is a derivative too. However, it is formally difficult to determine what would have been the word class of the Proto-Ugric word. MSzFE and UEW consider Hu -ét a deverbal nominalizer. Mansi LU also has the form šät- in the noun šät-khur 'Dämmerung': it is unclear what is the precise origin of this form.
Conclusion
A convincing Proto-Ugric etymology
