Did you know?

Latin anima means “breath” or “soul,” and animalis, the adjective that comes from it, means “having breath or soul.” An animal such as a cat or dog can be seen to breathe. Plants breathe too, by taking in certain gases from the atmosphere and releasing others. However, this process cannot be observed by the naked eye. So the noun animal, which comes from animalis, was borrowed from Latin for that group of living beings that breathe visibly.

Etymology

Noun

from Latin animal "living being that can move," derived from animalis "animate," from anima "soul, breath" — related to animate see Word History at animate

Word Origin

Latin anima means "breath" or "soul," and animalis, the adjective that comes from it, means "having breath or soul." An animal such as a cat or dog can be seen to breathe. Plants breathe too, by taking in certain gases from the atmosphere and releasing others. However, this process cannot be observed by the naked eye. So the noun animal, which comes from animalis, was borrowed from Latin for that group of living beings that breathe visibly.
