What does mister mean?
Mister is a respectful term for addressing a man, especially one whose name follows it, as in “Mister Morgan.” In less formal contexts, it can also mean a man generally, often with the implication that he is being addressed directly or treated as a stranger. The word is less formal than titles such as “doctor” or “professor,” and it is usually replaced by the shortened form “Mr.” in ordinary written correspondence. Historically, “mister” developed from “master,” a word for a person with authority or an accomplished practitioner. Over time, it became established as a polite form of address independent of the social rank originally suggested by “master.” Today, it can sound friendly, old-fashioned, or slightly teasing depending on context and tone.

Where does mister come from?
“Mister” is a historically altered form of “master,” which came through Old French from Latin magister, meaning “teacher,” “supervisor,” or “one who is authoritative.” The shortened form became established as a respectful address in the early modern period. It is closely related in origin to words such as “masterpiece,” “masterful,” and “mastery,” while the standard abbreviation “Mr.” reflects the same title in a more compact written form.
How mister is actually used
As a form of address, 'mister' is often shortened to 'Mr.' when used before a name, and the abbreviation conventionally includes a period. In informal American English, 'mister' can refer to any man, but the expression 'mister nice guy' is usually dismissive or ironic.
