means Full of energy, courage, and lively determination — animated in a way that draws attention and refuses to fade quietly.

from From "spirit," which comes through Old French from Latin "spiritus" — literally "breath, breathing," tied to "spirare," to breathe (the same root that gives us inspire and respire). The ancient idea was that the breath was the living animating force in a body; to be "spirited," then, is to be full of that breath of life — and the past-participle "-ed" turns it into a state of being charged with it.
