Borrowed from a North Germanic language, compare Old Norse þykkr (thick, bulky), from Proto-Germanic *þekuz. Karelian tykky has the same origin. The noun sense was originally found only in the dialects of Kainuu and its surroundings, and has been adopted from there into the written standard language. Dialectal variant forms include tykkä, tyhkä, tyhkeä, tykevä.[1]

  • In Finnish-origin texts this term is often translated as "crown snow-load" into English, but that term does not seem to be used by native English writers.
