An Etymological Dictionary of the German Language/Wieche
Wieche, m., ‘wick,’ from MidHG. wieche, m. and f., ‘twisted yarn as wick or lint,’ OHG. wiohha (wioh?), ‘wick’; also MidHG. and ModHG. (dial.) wicke, with the same signification. The latter is connected with Wickel, from which MidHG. wieche was orig. at all events quite distinct; comp. Du. wiek, ‘lamp wick,’ AS. weoca (but also wecca, equiv. to E. wick). There are apparently no other cognates, unless we include Wocken.
