My Flashcards

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'.

FAQ

Frequently Asked Questions

No, it is an obsolete historical unit. Its descendants are the modern 'ounce' (weight) and 'inch' (length).

It is pronounced /ˈʌnsɪə/, with the stress on the first syllable, similar to 'punter' but with an 's' sound.

You would encounter it in academic texts about ancient Roman history, archaeology, numismatics (the study of coins), or the history of science and measurement.

The plural is 'unciae', following the Latin first-declension pattern.
