My user name is Old English for "even(ing) gloaming," i.e., twilight, dusk. If I were being hyper-correct, I'd spell it with an ash, as æfenglommung.
I'm not sure if this word is recorded in the OE corpus, or whether I put it together in typical OE aglommerative fashion in junior high, but the word stuck with me from my first interest in matters Anglo-Saxon.
