Overview

An interval names itself from its number and its quality rather than from a fixed vocabulary, so its translation has to be looked up by the name it computed rather than registered against it ahead of time. Anything missing along the way – no locale asked for, no translations loaded, no entry under either heading – leaves the computed name standing.
