Temperaments
Tempering out this comma leads to a form of pessoal temperament.
Etymology
This comma was named by Aura in early 2023, for it is one of the defining commas in temperaments such as abigail in the 7-limit, and Abigail itself is a person's name, leading to the use of the Portuguese word pessoal (meaning "staff" or "folks"[1]) for this comma's temperament name, and thus the comma's name of "pessoalisma".
