I want to write a scientific paper and I am looking for a nice word that can describe a theory can be a basic component or a main tool for another theory. What is the best word that I can use?

  • Generally theories are based on assumptions! What do you mean by basic component/main tool? Sort of 'established evidence'?

  • @Josh61 One theory can not be an evidence for another in my opinion but can be like a pillar for another one.

    Fundament:an underlying theoretical basis or principle. Foundation/base : the basis on which a thing stands, is founded, or is supported.

Maybe one or more of the following words/compound words will suffice:

essential component

fundamental part

stepping stone


Perhaps 'subtheory' 'praxis' 'scaffolding' ...

  • Single word request answers need to be more than just a list of words. The most helpful of this type of answer gives a rationale and examples for the choices. Oct 16, 2014 at 8:14
