psuche (Greek #5590)
breath, i.e. (by implication) spirit, abstractly or concretely (the animal sentient principle only; thus distinguished on the one hand from 4151, which is the rational and immortal soul; and on the other from 2222, which is mere vitality, even of plants: these terms thus exactly correspond respectively to the Hebrew 05315, 07307 and 02416)
KJV usage: heart (+ -ily), life, mind, soul, + us, + you.
Pronounce: psoo-khay'
