IPA: /ˌæntiˈfæʃɪzəm/
KK: /æntiˈfæʃɪzəm/
A belief or movement that opposes fascism, which is a political system that emphasizes strong, centralized control and often includes authoritarianism and nationalism.
Many activists joined the antifascism movement to stand against oppressive regimes.
Antifascism is formed from "anti-" (meaning against) and "fascism" (from Italian "fascismo", meaning a political ideology characterized by authoritarianism and nationalism). The term refers to a movement or ideology that opposes fascism.
Think of 'anti-' meaning against, and 'fascism' as a specific authoritarian political ideology. This helps you remember that antifascism is about opposing that ideology.
