告捷 (gào jié) is a formal, literary verb meaning 'to announce victory' or 'to report success'. It combines 告 (gào), meaning 'to declare' or 'to announce', and 捷 (jié), meaning 'victory' or 'triumph' — often used in classical and modern written Chinese to denote decisive, commendable success. Though it literally means 'to announce victory', it functions more like 'to achieve and declare victory', emphasizing both the accomplishment and its formal announcement.

This term appears frequently in news reports, official statements, historical narratives, and celebratory contexts — especially when describing military triumphs, competitive wins (e.g., sports or exams), or major project milestones. It carries a positive, proud, and somewhat solemn tone, and is rarely used in casual daily speech. Because of its elevated register, it’s common in headlines, press releases, and ceremonial language, where concision and gravitas are valued.
