Conservatism
Etymology
From Latin conservare, “to keep, preserve,” from con- (intensive) + servare, “to guard.” The political noun took hold in the 1830s, borrowed into English partly from French conservateur; it drew on Edmund Burke’s earlier defense of tradition against revolutionary upheaval. What counts as the order worth conserving has shifted with each era, so the word’s content varies by time and place.
noun · /kun-SUR-vuh-tiz-um/
A political disposition that favors established institutions, gradual change, and inherited social order over rapid or sweeping reform.
What it names
The instinct to treat long-standing arrangements as accumulated wisdom worth preserving until change is clearly warranted — a stance about the pace of change as much as its direction.
Example
His conservatism was less about any single policy than a general wariness of reforms whose consequences no one could fully predict.
Related idea
Reactionary politics seeks to reverse change and restore an earlier order; conservatism, by contrast, characteristically aims to slow and temper change rather than undo it.
