Hebrew: "Sayings of the Fathers"
The only tractate in the Mishna that is devoted entirely to transmitting non-legal opinions. Aboth catalogs the wisdom sayings of rabbinic sages, including several of the 2nd temple period, without providing any connecting narrative frame. It was probably composed before & originally published independently of the Mishna, since it does not fit well in its current location in Neziqin, the order of tractates concerned with civil & criminal law. It is the only Mishna tractate that has no later commentary in the Talmud.
