Cornerstone

Building's first stone

A cornerstone is a stone forming part of a corner in a wall, especially one laid ceremonially at the foundation of a building.

The term extends to anything fundamental or essential: Free speech is a cornerstone of democracy.

A cornerstone supports and anchors what's built upon it—whether masonry or ideology.
