Mr
UK: ˈmɪstə(r) | US: ˈmɪstər
n. a title used before a man’s surname or full name as a courtesy, typically for adult males (equivalent to "Mister").
"Mr" is an abbreviation of "Mister," which originated from the Middle English term "maister" (master), derived from Old French "maistre" and Latin "magister" (chief, teacher). The truncation to "Mr" reflects English's tendency to shorten honorifics while preserving the initial consonant cluster ("M" + "r") for recognition. The dot (now often omitted) historically marked it as an abbreviation.
