adieu
UK[əˈdjuː]US[əˈduː]
interj
A word used to express farewell.
n
A farewell.
Etymology
The word 'adieu' entered English from Middle French in the 14th century, where it served as a conventional expression of farewell. Its French form is a contraction of the phrase "à Dieu," which translates literally as "to God." This phrase originated from the Old French "a Deu," itself derived from the Vulgar Latin "ad Deum," meaning "to God" or "I commend you to God." Thus, the modern abstract meaning of a formal or final goodbye retains the original sense of entrusting someone to divine protection upon parting.
Analysis
The word is a direct loan from French and functions as a single, unsegmentable unit in English.
