The word "小伙" is formed by directly combining two core concepts: "小" meaning "young" or "small", and "伙" meaning "companion" or "fellow", often within a group. It merges the idea of youth with the idea of a person in a social or working context, creating a single term that refers not just to a young male, but implicitly to one with a certain energy, spirit, or role among his peers. The formation is a straightforward conceptual blend, where the first character modifies the essential nature of the person indicated by the second.
