Definition
Meaning
A historical unit of measurement, specifically one twelfth of a Roman pound (approximately 27.3 grams) or one twelfth of a Roman foot (uncia).
It is the etymological origin of the modern words "ounce" and "inch" and is sometimes used in historical, numismatic, or metrological contexts to refer to these ancient fractions.
Linguistics
Semantic Notes
The meaning is strictly tied to its Roman origin as a fraction (1/12). It is not used in modern measurements but is referenced for historical accuracy. In numismatics, it can refer to a Roman bronze coin worth one twelfth of an 'as'.
