The term 'fail to care for' can be summarized as NEGLECT, which is defined as the act of failing to take proper care of something or someone. NEGLECT is often seen in cases of child abuse, where a parent or guardian fails to provide the necessary care and attention to a child. NEGLECT can also refer to the failure to maintain a property or to provide adequate medical care. In all cases, NEGLECT is an act of omission that can have serious consequences.
