The Etymology of Economic
Economic carries a household inside it. The Greek noun oikonomía (οἰκονομία) was simply household management — how a head of household allocated grain, livestock, money, and labour. Aristotle wrote a short treatise called Oikonomikós on the subject in the 4th century BCE. The compound is fully transparent: oîkos (house) plus nómos (law, management, rule, custom). Latin borrowed the word as oeconomia, and English picked up the adjective economic in the 16th century, originally meaning of household management. As Adam Smith, the Physiocrats, and the 18th-century political economists began to treat the production and exchange of an entire nation as analogous to a great household, the sense expanded outward — first to political economic, then to economic in its modern macro sense referring to whole markets, sectors, and policy. The Greek oîkos is also the source of ecology, ecosystem, and ecumenical — three further sciences of the household.
