Notes on Meaning
- The term "vô ước" is a compound of "vô" (without) and "ước" (divisor, measure, or to estimate). It strictly denotes the mathematical property of having no common measure. It is not used in everyday language to mean "unexpected" or "unestimated," which might be a potential false interpretation of its components.
