A feral 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. Others are alleged to have been brought up by animals; some are said to have lived in the wild on their own. Just over one hundred incidents have been reported in English.
