A feral child (also, colloquially, wild child) is a human child who has lived isolated from human contact from a very young age, and has no (or little) experience of human care, loving or social behavior, and crucially, of human language. Some feral children have been confined by people (usually their own parents); in some cases this child abandonment was due to the parents’ rejection of a child’s severe intellectual or physical impairment. Feral children may have experienced severe child abuse or trauma before being abandoned or running away. Feral children are sometimes the subjects of folklore and legends, typically portrayed as having been brought up by animals.
