G5594
ψύχω
psuchō
psoo‘-kho
A primary verb; to breathe (voluntarily but gently; thus differing on the one hand from 4154 which denotes properly a forcible respiration; and on the other from the base of 109 which refers properly to an inanimate breeze), that is, (by implication of reduction of temperature by evaporation) to chill (figuratively): - wax cold.
