/ˈfɔːs mæˈʒɜː, -ˈdʒʊə/
unexpected circumstances, such as war, that can be used as an excuse when they prevent sb from doing sth that is written in a contract 不可抗力（如战争，常指未能履行合约的原因）
The noun force majeure is a French term that literally means “greater force” or “superior strength.” It’s no ordinary occurrence, but something that is overwhelming and unexpected, like a war, a hurricane, or an asteroid landing on your roof. It’s also a legally valid excuse for not fulfilling an obligation or contract — everyone involved will agree that it was unavoidable.
