‘男孩’ (nánhái) literally combines two characters: ‘男’ (nán), meaning ‘male’ or ‘man’, and ‘孩’ (hái), meaning ‘child’. Together, they form a common noun meaning ‘boy’ — specifically a male child, typically under the age of 18. Unlike the more formal or literary term ‘男子’ (zǐnán), ‘男孩’ is neutral, widely used in everyday speech, writing, and education, and carries no strong connotations of age, status, or attitude.

The word appears frequently in contexts involving family, school, childhood development, and social descriptions — for example, when referring to students, siblings, or children in stories or news reports. It’s often paired with measure words like ‘一个’ (yī gè) or classifiers such as ‘这’ (zhè) or ‘那’ (nà). While ‘男孩’ emphasizes gender and youth, it does not imply immaturity or lack of capability — context determines nuance. It’s distinct from ‘儿子’ (érzi, ‘son’), which specifies a familial relationship.
