défi

Défi is a French noun meaning a challenge or test of one’s abilities or resolve. It can denote an invitation to prove oneself, an obstacle to overcome, or a bold proposition to test someone’s capabilities. The term comes from the verb défier, to defy or challenge, which derives from Latin diffidare ('to distrust').

Usage spans personal, social, and institutional contexts. A personal défi might be to complete a marathon; in organizations, a défi can be a project or goal set to stimulate performance. In sports, games, and competitions, a défi is a call to prove skill, speed, or endurance. In contemporary culture, people often issue défis on social networks—fitness, creativity, or skill challenges—framed as 'lancer un défi' and 'relever le défi'. The phrases 'faire face à un défi' and 'surmonter un défi' are common for describing how people respond to difficulties.

Synonyms and nuance: épreuve is a close synonym. In many contexts, défi is neutral or positive, but it can suggest risk or audacity when describing ambitious undertakings. The term is widely used in journalism, education, and everyday speech to denote a task that tests abilities, courage, or resolve.
