A more thorough explanation: In legal terms, a “lunatic” refers to a person who is considered mentally ill or insane, and as a result, lacks the capacity to manage their own affairs or make rational decisions. This term is often used in the context of legal proceedings related to guardianship, mental health, or competency.
Example: The defendant was found not guilty by reason of insanity due to being deemed a lunatic at the time of the crime.
