The quality or state of being rude, impolite, and discourteous; rudeness or incivility as a persistent character trait.
Formed from 'churlish' by adding the abstract noun suffix '-ness' (from Old English 'nes'). The '-ness' suffix transforms adjectives into abstract nouns representing qualities or states.
The '-ness' suffix is English's most productive way to create abstract nouns from adjectives—it's been working for over 1,000 years and speakers still spontaneously create new ones (like 'relatableness'), making it one of our most 'alive' grammatical patterns.
