Various 41edo 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.

A comma (the actual punctuation mark ",") is spoken as "add", thus Cv,7 is "C-down 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 41edo. 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 Kite guitar by bending the upminor 3rd up slightly more than half a fret.

P1-vm3-P5-M7 is named vm,M7 = downminor add major 7. One might think that the "add" could be omitted, and it could be named vmM7. But there's a rule that in a 7th chord, an initial arrow affects both the 3rd and the 7th. So vmM7 is a minor-major chord with both the 3rd and 7th downed, i.e. P1-vm3-P5-vM7.
