Comma-prefix names' are a systematic naming system for just intervals developed by CompactStar. Unmodified interval names correspond to Pythagorean intervals while prefixes can be added to indicate raising/lowering by a comma. The prefixes for lower primes are added first, for example 36/35 is an "oversuperunison" rather than a "superoverunison". In 2.3.p subgroups, most names in this system correspond to existing terms, such as 7/4 being a "subminor seventh", and 11/8 being an "ultrafourth", although when more than one non-Pythagorean prime is introduced, the names can sometimes become counter-intuitive.
