Synonym discussion

Sense: noun/1

These four words all name living non-human beings, but they pull in different directions. 'Animal' is the everyday word, neutral and used widely from children's books to news reports about wildlife. 'Creature' is softer and more imaginative — a children's book might describe 'small woodland creatures' or 'creatures from another planet' — and it covers anything that lives, including imagined ones. 'Beast' is older and stronger, suggesting a large, powerful, or frightening animal, and it appears mainly in stories, poems, or set phrases like 'beasts of burden'. 'Pet' is narrower again: it names an animal a person keeps at home for companionship, like a cat or hamster. So a tiger is an animal and a beast, a dragon is a creature, and a goldfish is a pet.

Etymology

LatinOld FrenchMiddle EnglishModern English

The word 'animal' came into English in the early 1300s from Latin 'animalis', meaning 'having breath' or 'living'. That Latin word was built from 'anima', which meant 'breath' or 'soul' — the same root that gives us 'animate' and 'animation'. The idea was simple: a thing with breath inside it is alive. English first borrowed it from Old French 'animal' before settling on the Latin spelling we still use today. The newer adjective senses (such as 'animal fat' or 'animal instinct') grew naturally out of the noun, while the insulting use for a cruel person dates back to the 1500s.
