Definition & Meaning of "guv'nor"in English

What does "guv'nor" mean in British slang?

The structure is a colloquial pronunciation of "governor," dropping the middle syllable and altering the vowel sound. It is used in British English, especially in working class and Cockney speech, to address a man, often showing respect (to a boss, employer, or authority figure) or familiarity (to a stranger in a shop or pub). People typically say "Alright, guv'nor?" or "Thanks, guv." The term originated in 19th century British English, where "governor" was used for someone in charge, and the shortened "guv'nor" became a common London address term, remaining a classic Cockney marker.
