prude
UK: pruːd | US: pruːd
n. a person who is excessively concerned with propriety or modesty, especially in a self-righteous or censorious manner.
The word "prude" originates from the Old French "prude" (feminine form of "prud"), meaning "wise" or "virtuous," derived from the Latin "prōdesse" (to be of value). Over time, its meaning shifted negatively in English to describe someone overly concerned with modesty or propriety, often with a judgmental tone. The silent "e" at the end is a remnant of its French feminine form.
