The term 'not domesticated' refers to animals that have not been tamed or trained by humans. This can be further broken down into three words: 'UNTAMED' (7 letters), 'FERAL' (5 letters) and 'WILD' (4 letters). 'UNTAMED' means not having been subjected to human control, while 'FERAL' implies an animal that has returned to the WILD after being domesticated. Finally, 'WILD' is used to describe animals that have never been domesticated. All three terms refer to animals that have not been domesticated by humans.
