The word 'supervisor' is a direct borrowing from Latin supervisor, meaning "overseer, inspector". It is composed of the prefix super- ("over, above") and the verb vidēre ("to see"), with the agent suffix -or. The literal sense is "one who oversees" or "one who looks over from above". This perfectly captures the modern managerial meaning: a person in a position of authority who watches over, directs, and inspects the work of others. The semantic journey from the physical act of "looking over" to the abstract concept of managerial oversight is straightforward and logical.
