The central idea ____ the observed structure

If central idea didn't exist or was taken out of the equation, the observed structure would no longer be observed.

I would like to use cornerstones, mainstays, etc. as verbs, but preferably an established word that has the same meaning: the subject is foundational to the object.

"support" doesn't work well enough because I also want to connote the idea that as soon as you remove the subject, the object totally falls apart, Jenga tower or house-of-cards style. Remove a table leg and watch the table fall over. Support doesn't imply absolute necessity.

I would prefer a single word to a compound word like props-up, and something with more gravitas: cornerstone, mainstay, keystone, foundation, sound so powerful, huge, and significant. But "props-up" sounds like a ramshackle job.

  • @YosefBaskin no, it's just one of the table legs, or one of the cards, or one of the jenga bricks. Not the glue.

    For a verb that can be used as a noun, try anchor. Oct 27, 2021 at 21:57
  • Try Variety.com, the online version of Variety. Hollywood has so many kingpins (and kingpin wannabes paying for ad space) that Variety writers had to get quite creative with their wording. It’s tamer than it used to be, but still a rich source of words and expressions.

The word underpin is primarily used to mean supporting a building from underneath, but can also apply to organisational structures. Lexico has

underpin
VERB

1 Support (a building or other structure) from below by laying a solid foundation below ground level or by substituting stronger for weaker materials.
At present, it is not thought that underpinning the foundations would be enough to save the building

2 Support, justify, or form the basis for.
The idea of fairness that underpins the democratic process is grounded in different ways in different theories.

So the sentence could be

The central idea underpinned the observed structure.

This conveys that the 'central idea' is essential for the 'observed structure' to exist, and the association with buildings and foundations gives it solidity.
