soundness

This term describes a state of integrity and reliability, whether applied to an abstract argument, a physical structure, or a financial entity. It conveys a sense of robustness and the absence of critical flaws, suggesting that the subject can withstand pressure or scrutiny without collapsing. As an uncountable noun, it does not have a plural form and cannot be counted with numbers. To refer to specific instances of this quality, one must use partitive constructions such as a degree of soundness or a measure of soundness.
