INVERSION, in Grammar, is where the words of a phrase are ranged in a manner not so natural as they might be. For instance, "Of all vices, the most abominable, and that which least becomes a man, is impurity." Here is an inversion, the natural order being, "Impurity is the most abominable of all vices, and that which least becomes a man." An inversion is not always disagreeable, but sometimes has a good effect.
