The House passed a bill striking the word ‘lunatic’ from federal laws. The Senate had previously passed a similar bill.

According to the New York Times, the word derives from the Latin word for moon and stems from the “ancient beliefs that people could become ‘moonstruck’ by lunar movements.” Mental health groups supported the bill, according to The Times report.  

In 2010, President Obama signed ‘Rosa’s Law,’ which replaced the term “mental retardation” with “intellectual disability” in federal laws.
