Enallage (e-nal’-la-ge): The substitution of grammatically different but semantically equivalent constructions.
This is crazy. That is insane. Between this and that is nothing–nothing without a name–not crazy, not insane. Rather, it makes the silence of juxtaposed equivalencies. Why might there be a third beat? 1. Crazy. 2. Insane. 3. Crackers.
There. There we have it and many more. With a little effort we could probably eke out ten beats more–with each beat shedding a subtly different glow, and casting a slightly different shadow on the silence between this and that.
Bonkers? Around the bend? Playing with half a deck? Nuts? Unhinged? Non compos mentis? A screw loose?
Educate yourself on madness’s nuances as they are reflected in its endless names. Like some god or goddess it has a protean character: endlessly named it morphs and remains the same.
Touched? Batshit? Whacky? Bananas?
