武士 (wǔ shì) literally means 'martial scholar' — combining 武 (wǔ), meaning 'military,' 'martial,' or 'warlike,' and 士 (shì), an ancient term for a 'scholar,' 'gentleman,' or 'elite man of virtue and service.' Historically, it referred to professional warriors in feudal China, especially during the Warring States and Han periods, who upheld codes of honor, loyalty, and martial skill. Over time, the term was adopted in Japanese as 'bushi' and became closely associated with the samurai class.

In modern Chinese, 武士 is used primarily in historical, literary, or cultural contexts — for example, when discussing classical Chinese texts, martial arts history, or East Asian feudal societies. It’s not used for contemporary soldiers or fighters; for those, terms like 军人 (jūn rén) or 战士 (zhàn shì) are preferred. The word carries connotations of discipline, moral integrity, and elite status beyond mere combat ability.
