We adopted a mother-daughter pair of cats and named them
Nyx and
Nemesis.
I guess I'd use
Nyx if I really had to use one of these.
*****
And last of all an Admiral came,
A terrible man with a terrible name,—
A name which you all know by sight very well;
But which no one can speak, and no one can spell.
Robert Southey, "The March to Moscow"
