anima
Anima (noun) means the soul or life force of a living being, as opposed to the animus.
Etymology
Borrowed from Latin anima (“a current of air, wind, air, breath, the vital principle, life, soul”), at times equivalent to animus (“mind”); both trace back to Proto-Indo-European *h₂enh₁- (“to breathe, blow”) — see animus. It is cognate with Ancient Greek ἄνεμος (ánemos, “wind”) and Old English anda (“anger, envy, zeal”). More at onde.
