5594. psucho (psoo'-kho)

a primary verb; to breathe (voluntarily but gently, thus differing on the one hand from pneo, which denotes properly a forcible respiration; and on the other from the base of aer, which refers properly to an inanimate breeze), i.e. (by implication, of reduction of temperature by evaporation) to chill (figuratively)

wax cold.
