Protectionism
Etymology
From Latin protegere, “to cover in front,” from pro- (“before”) + tegere (“to cover”). The economic -ism emerged in the nineteenth century, largely in opposition to free-trade doctrine, to name policies that “protect” home producers. It remains a neutral technical term even though it is often used as praise or reproach depending on the speaker’s economics.
noun · /pruh-TEK-shuh-niz-um/
An economic policy of shielding domestic industries from foreign competition through tariffs, quotas, or subsidies.
What it names
The recurring trade-off at the heart of trade politics — protecting home producers and jobs now against higher prices and lost efficiency later.
Example
The tariff was defended as protectionism to save local factories and attacked as a hidden tax on every shopper.
Related idea
Autarky is the extreme goal of total national self-sufficiency; protectionism usually aims only to shelter select industries, not to seal off trade entirely.
