Morphology

cornerstone = corner + stone (semi-transparent) = corner + stone

The metaphorical sense 'foundational or essential element' is derived from the literal compound but involves an abstract figurative extension that may not be fully predictable for all learners.

Etymology

Cornerstone comes from the image of a corner stone that holds a building's base, so people began to use it for any main idea that supports something. That's why calling honesty a cornerstone means it is an essential 'support' that everything else depends on.
