wiktionary
Borrowed from Latin oeconomia, from Ancient Greek οἰκονομία(oikonomía, “management of a household, administration”), from οἶκος(oîkos, “house”) + νέμω(némō, “distribute, allocate”) (surface analysis eco- + -nomy). The first recorded sense of the word economy, found in a work possibly composed in 1440, is “the management of economic affairs”, in this case, of a monastery.
