Mister

Mister, often abbreviated as "Mr.," is a title used to address or refer to adult men. It is placed before a man's surname or full name as a sign of respect or formality. The term is derived from the Middle English "maister," which meant "master." While traditionally used for married or unmarried men alike, it does not specify marital status. In various contexts, such as business, education, and social interactions, using "Mr." followed by a last name is a common practice to maintain professionalism and politeness.
