Word of the Day : Alienist

Did You Know?
Alienist looks and sounds like it should mean "someone who studies aliens," and in fact alienist and alien are related—both are ultimately derived from the Latin word alius, meaning "other." In the case of alienist, the etymological trail leads from Latin to the French noun aliéniste, which refers to a doctor who treats the mentally ill. Alienist first appeared in print in English about mid-19th century. It was preceded by the other alius descendants, alien (14th century) and alienate (used as a verb since the 15th century). Alienist is much rarer than psychiatrist these days, but at one time it was a common term.

Although currently not often used in common parlance, the term "alienist" is still employed in psychiatric hospitals to describe those mental health professionals
