גפנים מותרין. גפנים בקטנה ⁠— מותר לזרוע את הגדולה.

The vines, however, are permitted, as the small courtyard does not extend into and impact upon the large one. The converse is also true: If there are vines in the small courtyard, it is permitted to sow other crops in the large one ab initio, even if they are not planted 4 cubits away from the vines, because the vines are not considered to be located in the larger courtyard, and therefore there is no prohibition whatsoever.

אשה בגדולה וגט בקטנה ⁠— מתגרשת. אשה בקטנה וגט בגדולה ⁠— אינה מתגרשת.

Likewise, if there were two adjacent courtyards, and a wife, who owned both courtyards, was standing in the large courtyard, and her husband threw her a bill of divorce into the small courtyard, she is divorced. Her presence in the larger courtyard extends to the smaller one, and she is therefore considered to be standing in the small courtyard. If, however, the wife was in the small courtyard and the bill of divorce was thrown into the large one, she is not divorced.

צבור בגדולה ושליח צבור בקטנה ⁠— יוצאין ידי חובתן. ציבור בקטנה ושליח צבור בגדולה ⁠— אין יוצאין ידי חובתן.

Likewise, with regard to communal prayer, if the congregation was in the large courtyard, and the prayer leader was in the small one, they fulfill their obligation through his prayer, as the congregation is considered to be in the small one as well. However, if the congregation was in the small courtyard, and the prayer leader was in the large one, they do not fulfill their obligation.

תשעה בגדולה ויחיד בקטנה ⁠— מצטרפין. תשעה בקטנה ואחד בגדולה ⁠— אין מצטרפין.

The same principle applies to a prayer quorum: If there were 9 men in the large courtyard and one man in the small one, they join together to form the necessary quorum of 10, as the small courtyard is subsumed within the large one, and the individual is considered to be in the large courtyard. However, if there were 9 men in the small courtyard and one in the large one, they do not join together.
