undergird
Brace from below
Undergird means to provide underlying support or foundation for something.
The literal sense—securing from beneath with a girdle or band—is rare; the figurative dominates: A commitment to fairness undergirds the legal system.
Policies, beliefs, or principles undergird institutions, arguments, or movements.
The word implies structural support that may not be visible but is essential.
