What does expansionary mean?
Expansionary is an adjective describing something that promotes or drives expansion, most commonly in economics. An expansionary policy is one deliberately designed to enlarge economic activity: governments pursue expansionary fiscal policy by cutting taxes or raising public spending, while central banks adopt expansionary monetary policy by lowering interest rates or increasing the money supply. The word also appears more broadly to describe periods of growth in businesses, markets, or organizations, as when a company enters an expansionary phase by opening new offices abroad. Its natural opposite is contractionary, which describes policies that restrain rather than stimulate demand. Largely confined to formal contexts — financial journalism, academic writing, and policy debate — expansionary carries connotations of stimulus, optimism, and deliberate growth. It derives from Latin expandere, meaning to spread out or unfold, via English expand and expansion, making it part of a family of words all rooted in the idea of spreading outward.
Tending to promote or cause expansion, especially of economic activity, output, or public spending.
"Critics warned that such an expansionary fiscal stance could reignite inflation."
Almost always used of policies, budgets, interest-rate settings, or phases of growth; rarely applied to physical objects.
Characterized by expansion or growth in scale, scope, or territorial reach, as of a company, market, or organization.
"During its most expansionary decade, the firm acquired fourteen smaller competitors."
When economists say "expansionary," they usually mean one thing: spend more, print more, grow faster — the word is practically a synonym for economic optimism.

Etymology of expansionary
Expansionary derives from Latin expandere, meaning "to spread out" or "unfold," formed from ex- ("out") plus pandere ("to spread"). The word entered English through the noun expansion, borrowed from Latin expansio, with the adjective suffix -ary added to form expansionary, first attested around the early nineteenth century alongside the rise of modern economic thought. It shares this root with cognates such as expansive, expatiate, and even pace-related words like pace itself, since pandere also underlies the notion of spreading or stepping out.
