Various 24edo triads, 6th and 7th chords, named via ups and downs. Not meant to be exhaustive, but this list does demonstrate the basic rules for naming. ^M6 and vm7 are the same interval, and chords that use that interval can be named as either a 6th chord or a 7th chord.

A comma (the actual punctuation mark ",") is spoken as "add", thus C^,7 is "C-up add-seven". The only exception is when a comma separates two numbers, as in C4,7 which is "C four-seven". A comma is written, and "add" is spoken, whenever not doing so would cause confusion with another chord. C^,~6 is clear without a comma if limiting oneself to 24edo. However, 53-edo and other edos have an upmid 3rd and 7th, and C^~6 would be P1 ^~3 P5 ^~6. In addition, "upmid" is a general term for slightly sharp neutral. One could play an upmid chord on a 24edo guitar by bending the mid 3rd up slightly.
