Freeze: a transitional state, the moment between being animated by energy, embodying it in a free state, to being motionless, embodying it only in potential; to turn  from flame to charcoal, water to ice, body to corpse, lizard to rock. In many of these cases, potential energy can be translated again into free energy by will; in others, an outside impulse is needed, such as the sun. Confusing the two has been the source of much error.
