δίςdís · G1364twice
ψυχήpsychḗ · G5590breath, i.e. (by implication) spirit, abstractly or concretely (the animal sentient principle only; thus distinguished on the one hand from G4151 (πνεῦμα), which is the rational and immortal soul; and on the other from G2222 (ζωή), which is mere vitality, even of plants: these terms thus exactly correspond respectively to the Hebrew H05315, H07307 and H02416)
