tursk-

Da. turse <- ON þurs -> PGerm. *þurasa-, *þur(i)sa- "troll, giant"
->(loan) Fi. tursas "sea monster"
->
Da. tosse "foolish person"

PGerm.*þursk-
Da.dial. tyske "troublesome person, supernatural being"
+ reinforcing u-
Da. utyske "repulsive monster, unruly person"

So, PGerm. both *þurs- and *þursk-, which means either *-k- was a
suffix (most likely NWBlock) or both *turs- and *tursk- were picked up
from a pre-Germanic substrate.
