Announcing an exciting new vocabulary acquisition: evert. I have needed this word many times, but had to resort to flipping, reversing, inverting, turning… inside-out.

Evert – verb [ with obj. ]
Turn (a structure or organ) outward or inside out: (as adj. everted) : the characteristic facial appearance of full, often everted lips.
DERIVATIVES
eversible – adjective.
eversion –  noun
ORIGIN mid 16th cent. (in the sense ‘upset, overthrow’): from Latin evertere, from e- (variant of ex-) ‘out’ + vertere ‘to turn.’

Now I can say things like:

• Everything in the world is the world everted.
• A comedy is an everted tragedy. A tragedy is an everted comedy.
• A pearl is an everted oyster shell. An oyster coats the ocean with mother-of-pearl. Outside the shell is ocean, inside the pearl is ocean. Between inner-shell and outer-pearl is slimy oyster-flesh, which ceaselessly coats everything it isn’t with mother-of-pearl. It is as if the flesh cannot stand anything that does not have a smooth, continuous and lustrous surface. We could call the flesh’s Other — that which requires coating — “father-of-pearl”.
• Imagine Pandora’s box as a pearl everting to an all-ensconcing shell as Pandora opened it, and Eden as an all-ensconcing shell everted to a pearl upon Adam’s eviction.
• An object is an everted subject.
