'少年' (shàonián) literally combines '少' (shào), meaning 'young' or 'few', and '年' (nián), meaning 'year' or 'age'. Together, it refers to a male youth or teenager—typically someone between roughly 13 and 19 years old. While historically gendered (often implying 'young man'), modern usage is increasingly neutral, especially in formal or literary contexts, though context may still suggest gender.

The term carries a positive, energetic connotation—evoking vitality, idealism, and potential. It appears frequently in literature, education, media, and official discourse (e.g., '少年中国' — 'Young China'). Unlike colloquial terms like '小孩' (xiǎohái, 'child') or '青少年' (qīngshàonián, 'adolescent'), '少年' is slightly more refined and often used in set phrases, slogans, or written language rather than casual speech.
