Argument's foundation (5)

Ross

I believe the answer is:

basis

(Other definitions for basis that I've seen before include "Underlying support for a theory" , "Foundation, fundament" , "Principle on which a theory is founded" , "grounds" , "Principal element" .)

I've seen this clue in the Universal.
