**niukilō n.w.n.(n) nickel. [Pgmc nekwe- +ilō]
Some further research since publishing the lesson of Gothic for Goths in which this word appears suggests that a better derivation might be niqilō if traced back to ProtoGermanic origins (from nekwe-), but as a borrowed word from english "nickel," nikilō might be more appropriate. Personally, i like it the way it is.
