{Eruvin 23b continues}
And if he had only let it be heard that the halacha was like Rabbi Akiva, I would have believed that if it is long and narrow, no. Therefore he informs us that the halacha is like Rabbi Yossi, such that it is the case even if it is long and narrow.

{Eruvin 24a}
Rav Nachman cited Shmuel: A {wood-}shed greater than a bet satayim {the space needed to grow 2 seah of grain} which was not fenced in for the purpose of habitation, how should he conduct himself {to allow carrying therein}? He should breach in it a breach wider than 10 cubits, and then fence it in such that the breach is 10 cubits {or less} for the purposes of habitation, and it is sufficient, for it is reckoned as if it was entirely fenced in for habitation, and it is permitted to carry therein, for it is like a courtyard.

{Eruvin 23a}
Mishna:
Rabbi Illai said: I heard from Rabbi Eliezer that even if it is a bet kor {a larger area, the amount needed to grow a kor}.
And I also heard from him: If one of the residents of a courtyard forgot to make an {= join in the joint} eruv {chatzerot}, his house is forbidden to him to carry in and out of it, but to them {the other residents of the courtyard}, it is permitted.
And I also heard from him: People may fulfill their obligation {of eating maror} on Pesach by eating harts-tongue {or palm ivy}.
However, a went around to all his students finding a fellow {who said the same in his name} and I found none.

{Eruvin 25b}
Gemara:
{The Mishna had said:} "And I also heard from him: If one of the residents of a courtyard...":
But we learnt {vehatania - our gemara vehatnan - a reference to the Mishna on Eruvin 69b}: His house is forbidden to carry in and out, both for him and for them!
Rav Huna bar Chinena said {our gemara: Rav Huna the son of Rav Yehoshua cited Rav Sheshet}: This is no difficulty. This {our Mishna} is Rabbi Eliezer and this {the later Mishna} in the Sages.

{Eruvin 26a}
Rav Sheshet said: On consideration you will find that based on the statement of Rabbi Eliezer, if he {the tenant of the courtyard who forgot} nullifies his rights in the courtyard, his rights in his house is also nullifed. And according to the words of the Sages, if he nullifies his rights in the courtyard, his rights in his house is not nullified.
And five people who live in one courtyard, and one of them forgot and did not make an {= join in the} eruv, according to Rabbi Eliezer, when he nullifies his rights, he need not nullify his rights to every single one. According to the Sages, when he nullifies his rights, he needs to nullify his rights to each and every one. And if he reveals his intent and states: I nullify my rights to my courtyard and my rights to my house, even according to the Sages, since he revealed his intent, it is revealed, and in fact nullified.

With all {kinds of food} we may make an eruv {of courtyards} and a shittuf {of alleyways}, except with water and salt.
