Eruvin (Hebrew: עֵרוּבִין, lit. "Mixtures") is the second tractate in the Order of Moed in the Talmud, dealing with the various types of eruv. In this sense this tractate is a natural extension of Shabbat; at one point these tractates were likely joined but then split due to length.
The Ra'ya Mehemna (14th century) introduced ענ״י as an acronym for "Eruvin, Niddah, and Yevamot". According to Jacob Emden, עני destitute is a pun which references the reputed difficulty of these tractates, and the acronym serves to warn off students. Eliezer Sofer uses it for "Eruvin, Nazir, Yevamot", arguing that Nazir is more difficult, and some also use "Eruvin, Nedarim, Yevamot".
