In both American and Brazilian English, 'linchpin' has evolved from a purely mechanical term to a widely used metaphor in business, politics, and academic contexts. In Brazil, 'peça-chave' is the most commonly used idiomatic equivalent, while Portuguese speakers tend to preserve more mechanical terminology. The word carries weight in corporate presentations and strategic discussions in both cultures, often used to identify critical success factors or key personnel.
