Definition

Linguistics
Semantic Notes
Primary modern usage is as a noun referring to an ignorant person. As a historical term (capitalized: 'Know-Nothing'), it is neutral. It can be used as a compound adjective (e.g., 'know-nothing attitude').
Dialectal Variation
British vs American Usage
Differences
The historical political party reference is specific to US history, making that sense almost exclusively American. The derogatory term for an ignorant person is understood in both varieties but may be less common in modern British English, where terms like 'ignoramus' or 'philistine' might be preferred.
Connotations
Strongly pejorative when referring to a person's ignorance. The historical term carries connotations of nativism, prejudice, and secrecy.
Frequency
More frequent in American English due to the historical term and its continued metaphorical use in political/cultural commentary.
