The Chinese word **班长 (bānzhǎng)**, meaning "class monitor" or "squad leader," is a compound noun formed through semantic combination. The first character, **班 (bān)**, signifies a group, such as a class, squad, or team. The second character, **长 (zhǎng)**, means a chief, head, or leader. When combined, they create a straightforward descriptive structure meaning "the leader of the class/squad," where the relationship is essentially "[group] + [head]" to denote the person in charge of that specific unit. This is a common and logical pattern in Mandarin for forming titles.
