Well, it's getting cooler again. The wind starts to remove the leaves from the trees and you desire your warm and comfortable sweaters. But don't be too quick to act. Perhaps you should undress the way our arboreal friends do.
The first syllable is a little rough, it's true, but be gentle with it and it shall return the favour. Then the D follows sweetly into the Y's short I, as in dizzy. And if we're lucky, removing our outer layer is dizzying. So that I is a long E that moves nicely to the schwa of the A. Then, as always, we love the ending. That L leaves our tongue on the backs of our teeth, pushing softly and seductively.
I've given you a few hints about the meaning. Have you been paying attention?
adj. -- related to the shedding or casting off of an outer coat or integument by snakes, crustaceans, etc.
There is a related term that provokes thoughts of eroticism coined by H.L. Mencken: Ecdysiast. It means An erotic dancer who removes their clothes as a form of entertainment; a stripper. So everyone can be ecdysial and an ecdysiast if they wish. And I'm sure that everyone has someone in their lives that wishes they would.
