The pessoalisma (monzo: [31 -6 -2 -6⟩, ratio: 2147483648/2144153025) is an unnoticeable 7-limit comma with a value of approximately 2.69 cents. Tempering it out leads to a form of pessoal temperament. Named by Aura in early 2023, this comma 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".
