The word "别人" is formed through the direct and logical combination of two individual characters: "别", which carries the core meaning of "other" or "separate", and "人", which means "person". When placed together, they construct a compound idea where the quality of "otherness" is applied directly to the concept of a person, conceptually creating the distinct category of "other people" or "another person", separate from the self or a defined in-group. It is a straightforward semantic fusion where the first character modifies the second to produce a new, unified meaning.
