5594.  Strong's Dictionary Study



5594. psucho {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), i.e. (by implication of reduction of 
temperature by  evaporation) to chill (figuratively): --wax cold.
