Minor tractate in the context of "Pirkei Avot"

Pirkei Avot (Hebrew: פִּרְקֵי אָבוֹת, romanized: pirqē aḇoṯ, lit. 'Chapters of the [Fore]fathers'; also transliterated as Pirqei Avoth or Pirkei Avos or Pirke Aboth, also Abhoth), is a compilation of the Jewish theological and ethical teachings and maxims from Rabbinic Jewish tradition. It is part of didactic Jewish ethical literature. Because of its contents, the name is sometimes given as Ethics of the Fathers. Pirkei Avot consists of the Mishnaic minor tractate of Avot, the second-to-last tractate in the order of Nezikin in the Mishnah, plus one additional chapter. Avot is unique in that it is the only tractate of the Mishnah dealing solely with ethical and moral principles; there is relatively little Halakha (Jewish law) in Pirkei Avot.
