The word 'supervisory' is built upon the Latin verb supervidēre, meaning "to oversee". This verb itself is a compound of the prefix super- ("over, above") and vidēre ("to see"), creating the literal sense of "to see over". The English verb 'supervise' was adopted from the Medieval Latin supervisus, the past participle of supervidēre. The adjective 'supervisory' then formed by adding the adjectival suffix '-ory' to the agent noun 'supervisor', which itself comes from the Latin supervisor ("overseer"). Thus, the modern meaning retains the core logic of its ancient components: an action or role that involves watching over or having a higher perspective on a situation.
