Götterdammerung

So while looking for words for my culinary alphabet, I found this word and thought that it was amazing!
It can be written both capitalized or in lower-case, and it is a noun.
The AHD defines it as:
A turbulent ending of a regime or institution.

The word comes from Götterdämmerung, an opera by Richard Wagner. It is of German origin and the word itself means "twilight of the gods" (quite impressive). Broken down, the root is the German götter-, the plural of Gott (god). The word passed through MHGer. as got from OHGerman.

I just really enjoy saying the word and think it should be used more often!
