the.com/mixed economy

means An economic system that blends free-market enterprise with government intervention, letting private businesses operate while the state regulates, taxes, and provides certain services.

from The phrase is a straightforward 20th-century political-economy coinage, not a word with ancient roots. 'Mixed' (from Latin miscere, to mix) was paired with 'economy' (from Greek oikonomia, 'household management') once thinkers in the early-to-mid 1900s needed a term for systems that were neither pure laissez-faire capitalism nor full state socialism — especially as Western nations built welfare states and regulated markets after the upheavals of the Great Depression and world wars. It's less a story of etymology than of vocabulary catching up to policy.
