1570s, "pertaining to household management;" from economic + -al (1). Sense of "pertaining to political economy" is from 1781, but that sense more commonly goes with economic, and the main modern sense of this spelling is "thrifty" (1780). Related: Economically.

1530s, "household management," from Latin oeconomia (source of French économie, Spanish economia, German Ökonomie, etc.), from Greek oikonomia "household management, thrift," from oikonomos "manager, steward," from oikos "house, abode, dwelling" (cognate with Latin vicus "district," vicinus "near;" Old English wic "dwelling, village," from PIE root *weik- (1) "clan") + nomos "managing," from nemein "manage" (from PIE root *nem- "assign, allot; take").

The meaning "frugality, judicious use of resources" is from 1660s. The sense of "wealth and resources of a country" (short for political economy) is attested from 1650s, but even in the 1780s the American Founders in laying out the new republic generally used economy only as "frugality." So also in that sense in the Federalist, except in one place where full political economy is used.

Col Mason — He had moved without success for a power to make sumptuary regulations. He had not yet lost sight of his object.

[Madison, Sept. 13, 1787, in Farrand, "Records of the Federal Convention;" the motion was agreed to without opposition]
