Pirkei Avot
Pirkei Avot (Hebrew: פרקי אבות) (also Pirkei Avoth or Pirkei Avos or Pirke Aboth), which translates to English as Chapters of the Fathers, is a compilation of the ethical teachings and maxims of the Rabbis of the Mishnaic period. It is part of didactic Jewish ethical Musar literature. Because of its contents, it is also called Ethics of the Fathers. Pirkei Avot consists of the Mishnaic tractate of Avot, the second-to-last tractate in the order of Nezikin in the Mishnah, plus one additional chapter. Pirkei Avot is unique in that it is the only tractate of the Mishnah dealing solely with ethical and moral principles; there is little or no halacha (laws) found in Pirkei Avot.
Translation of the title
In the Mishnaic sense, the word avot, meaning "fathers", refers to fundamentals, or principal categories. Thus, the principal categories of creative work forbidden on Shabbat are called avot melacha, and the principal categories of ritual impurity are referred to as avot tum'ah. Perakim, or in the construct form pirkei, means "chapters". Thus Pirkei Avot means "Chapters of Fundamental Principles".
