rightness
This term describes a state of alignment, whether with a moral code or a factual standard. When used in an ethical sense, it carries a weight of virtue and integrity, often appearing in philosophical discussions regarding the inherent goodness of an action. It suggests a qualitative state of being just rather than a simple adherence to rules.
In a practical or technical sense, the word denotes precision and suitability. It describes the feeling that a choice or a calculation is exactly correct for the specific circumstances. Because it is an abstract quality, it is an uncountable noun and cannot be pluralized or counted with numbers; instead, it requires partitive constructions like a sense of rightness if one wishes to quantify the feeling.
