“Feral” refers to something that is wild, untamed, or having returned to a natural, undomesticated state. It is often used to describe animals that were once domesticated but have reverted to a wild way of living, such as feral cats or feral horses.
Metaphorically, “feral” can also describe a person or behavior that is raw, instinctive, or unrestrained, often associated with wildness or a lack of control.
