1)[line 2]של זה...SHEL ZEH...- of Bunyas (and he is therefore worthy of more honor than the second person who arrived)
2)[line 5]אל תשגרהוAL TESHAGREHU- do not send him
3)[line 7]"ישב עולם... חסד ואמת מן ינצרוהו""YESHEV OLAM... CHESED V'EMES MAN YINTZERUHU"- "May he be enthroned before HaSh-m forever; appoint lovingkindness and truth to preserve him" (Tehilim 61:8) - The Gemara interprets this verse homiletically to mean, "The world will be settled (i.e. will prosper) and will be protected when there are rich people who provide food and other necessities for the poor."
4)[line 10]יתד של מחרישהYASED SHEL MACHAREISHAH- (O.F. cheville) (even) the spike of a plow (used for making furrows). (Rabah bar bar Chanah is answering the question of the Gemara earlier of "Heichi Dami Tefisas Yad?")
5)[line 12]דבר הניטל בשבת אוסרDAVAR HA'NITEL B'SHABBOS OSER- [if a landlord has] an object which may be taken on Shabbos (i.e. it is not Muktzah) [in the house of his renter who did not join in the Eruv,] it forbids [the inhabitants of that Chatzer to carry]. Since the current inhabitant has the ability to remove it at any time, the presence of the object does not constitute Tefisas Yad.
6)[line14]עששיתASHASHIS- a lump of metal
7)[line 22]שכבר הסיע מלבוSHE'KEVAR HISI'A MI'LIBO- for he has already removed any thought [of dwelling in his house for that Shabbos]

9)[line 25]שבין שתי חצירותSHE'BEIN SHTEI CHATZEROS- which is half in one Chatzer and half in another
10)[line 27]מתוך אוגנוMI'TOCH OGNO- within its embankment (i.e. the ten-Tefach Mechitzah is completely within the well. This does not necessarily mean that it is touching the water.)
11)[line 30]לא תהא מחיצה גדולה מן הכותל שביניהםLO TEHEI MECHITZAH GEDOLAH MIN HA'KOSEL SHE'BEINEIHEM- a Mechitzah [above the well] should be no worse than the wall dividing the Chatzeros (which passes over the well and divides it according to Rebbi Yehudah)
12)[line 31]למטה ממשL'MATAH MAMASH- at the bottom of the airspace of the well, i.e. just above the water in the well
13)[line 32]למעלה ממשL'MA'ALAH MAMASH- at the top of the airspace of the well, i.e. just under the upper edge of the well

16)[line 36]דעריבי מיאD'ARIVEI MAYA- the water from the two halves of the well mingle below the Mechitzah
17)[line 37]נמי הא עריבי מיאNAMI HA ARIVEI MAYA- when the entire ten-Tefach Mechitzah is grounded on the very bottom of the well, the water from the two halves of the well may mingle above the Mechitzah as well
18)[line 40]ראשן של קניםROSHAN SHEL KANIM- the ends of the reeds (of which the Mechitzah is woven)
19a)[line 46]קורה ארבע מתרת בחורבהKORAH ARBA'AH MATERES B'CHURVAH- if a four-Tefach wide Korah is lying above a Churvah, it is permitted to carry under it as if the area below it were a Reshus ha'Yachid (due to Pi Tikrah Yored v'Sosem - see next entry)
b)[line 46]קורה ארבע מתרת בחורבהKORAH ARBA'AH MATERES B'CHURVAH (PI TIKRAH YORED V'SOSEM)
(a)The Torah requires Mechitzos (partitions) for various Halachos (e.g. defining a Reshus ha'Yachid for the purposes of carrying on Shabbos and creating a Kosher Sukah). A Mechitzah must be ten Tefachim high and enclose an area of four by four Tefachim. (See Insights Eruvin 86a.)
(b)When an area is covered by a roof, a Halachah l'Moshe mi'Sinai states that the edge of the beams of the roof "descends and encloses" (Pi Tikrah Yored v'Sosem), even though that side is completely open and has no physical partition. We may consider the area enclosed for Halachic purposes (see Insights to Eruvin 25:2). Amora'im argue as to whether Pi Tikrah can be used to enclose all four sides or only to enclose three sides when one Mechitzah already exists (according to RASHI; see Insights ibid.).
(c)In certain instances, Pi Tikrah cannot be applied:
1.Pi Tikrah is not applied to a roof that is sloped.
2.According to TOSFOS (Eruvin 86b DH Gezuztera), citing RASHI (Sukah 18b), it is not applied unless the roof beam is at least one Tefach thick.
3.According to TOSFOS (Eruvin 86b ibid.), it does not apply when the height of the roof beam is corrugated rather than smooth.

20)[line 2]ומייתיU'MAISI- and brings up water from the other side (past the partition)
21)[line 4]אלא משום דקל הוא שהקילו חכמים במיםELEH MI'SHUM D'KAL HU SHE'HIKILU CHACHAMIM B'MAYIM- and since the Chachamim allowed a hanging Mechitzah to divide water, we understand the Machlokes between Beis Hillel and Beis Shamai in the Mishnah to be as Rav Huna (and not Rebbi Yehudah) described it earlier
22)[line 12]המשלשל דפנות מלמעלה למטהHA'MESHALSHEL DEFANOS: MIL'MA'ALAH L'MATAH- [(O.F. trecier) to weave, to plait] one who weaves curtains to be the walls of his Sukah, from the top on down
23)[line 23]דאיסור סקילהISUR SEKILAH- although carrying from one Reshus ha'Yachid to another is only Asur mid'Rabanan (and therefore not an Isur Sekilah), whenever the Chachamim enact a decree they pattern it after the Torah law (Kol d'Sakun Rabanan k'Ein d'Oraisa Takun)
24)[line 24]אותו מעשה שנעשה בציפוריOSO MA'ASEH SHE'NA'ASEH B'TZIPORI- The happening which occurred in the town of Tzipori, where Rebbi Yosi was the ruling authority. After the death of Rebbi Yosi, his son Rebbi Yishmael took over his father's position. The story soon follows, on line 30.
25)[line 28]פרסו סדין על העמודים והביאו ספר תורהPARSU SADIN AL HA'AMUDIM V'HEVI'U SEFER TORAH- The Sefer Torah was in a Chatzer in which no Eruv had been made. Sheets were spread between poles - constituting hanging Mechitzos - between the house where the Sefer was and the synagogue. This created a private Mavoy which had only one house open to it, and therefore no Eruv was required in order to carry within it.
26)[line 30]שאין עושין אהל עראי בשבתEIN OSIN OHEL ARA'I B'SHABBOS
(a)It is prohibited mid'Oraisa to build on Shabbos (Mishnah, Shabbos 73a). The Melachah of Boneh (building) includes the construction of new structures on the ground as well as building permanent additions to pre-existing such structures.
(b)The Tana'im argue as to whether it is permitted on Shabbos to attach a temporary addition to a structure. Building a temporary structure in the first place, however, is prohibited according to all opinions.
(c)The Rishonim disagree as to whether this prohibition applies only to horizontal additions, such as placing a cover over a skylight, or also to vertical additions, such as placing a shutter in a window (see Insights).
27)[line 35]גזוזטראGEZUZTRA- A platform [jutting out from a wall over a body of water]
