early 14c., "any sentient living creature" (including humans), from Latin animale "living being, being which breathes," noun use of neuter of animalis (adj.) "animate, living; of the air," from anima "breath, soul; a current of air" (from PIE root *ane- "to breathe;" for sense development, compare deer).
A rare word in English before c. 1600, and not in KJV (1611). Commonly only of non-human creatures. It drove out the older beast in common usage. Used derisively of brutish humans (in which the "animal," or non-rational, non-spiritual nature is ascendant) from 1580s.
