animal: [14] Etymologically, an animal is a being which breathes (compare DEER). Its immediate source was the Latin adjective animālis ‘having a soul’, a derivative of the noun anima ‘breath, soul’ (which also gave English the verb and adjective animate [15]). Anima is a member of a set of related words in which the notions of ‘breath, wind’ and ‘spirit, life’ are intimately connected: for instance, Greek ánemos ‘wind’ (possible source of English anemone), Latin animus ‘spirit, mind, courage, anger’ (source of English animosity [15] and animus [19]), Sanskrit ániti ‘breathe’, Old English ōthian ‘breathe’, Swedish anda ‘breath, spirit’, and Gothic usanan ‘breathe out’.
The ‘breath’ sense is presumably primary, the ‘spirit, life’ sense a metaphorical extension of it. => anemone, animate, animosity, animus
early 14c. (but rare before c. 1600, and not in KJV, 1611), "any living creature" (including humans), from Latin animale "living being, being which breathes," neuter of animalis "animate, living; of the air," from anima "breath, soul; a current of air" (see animus, and compare deer). Drove out the older beast in common usage. Used of brutish humans from 1580s.
late 14c., from animal (n.). Animal rights is attested from 1879; animal liberation from 1973. Animal magnetism originally (1784) referred to mesmerism.
