lunacy etymology

Etymology

• Old French lunacie
• Medieval Latin lunaticus
• Latin luna ("moon") + -aticus (adjective suffix)

Meaning and Origin

Meaning:

Lunacy refers to a state of extreme mental disturbance, often characterized by bizarre behavior, delusions, and hallucinations.

Origin:

• The term "lunatic" originates from the ancient belief that the moon's phases could influence human behavior and mental health.
• The Romans believed that the full moon could cause mental instability, and they referred to individuals who exhibited extreme behavior during this time as "lunatici" (moon-struck).
• This belief persisted throughout the Middle Ages and into the Renaissance, leading to the term "lunacy" being used to describe mental illness.
• It was not until the 19th century that scientific advancements in psychiatry challenged this belief and recognized mental disorders as independent from lunar influence.
