A belief or attitude that opposes the ideals and values of romanticism, which often emphasizes emotion, nature, and individualism.
The artist's work reflects a strong sense of antiromanticism, focusing instead on realism and social critique.
Antiromanticism is formed from "anti-" (meaning against) and "romanticism" (from French *romantisme*, meaning a movement emphasizing emotion and individualism). The word refers to a stance or belief that opposes the ideals and values associated with romanticism.
Think of 'against' ('anti-') the emotional and individualistic ideals of 'romanticism' — that's what antiromanticism means.
