οἰκονόμος oikonomos

A masculine noun for the manager of a household or estate, usually a slave or freedman, and more widely an administrator or steward. With “of the city” (Rom 16:23) it names a civic manager; some English versions render that phrase “treasurer,” as in “the city treasurer” (BSB). The entry records those lexical uses. It does not identify a named person with an inscription or fix a later civic rank.
