DAF HASHAVUA 'עירובין ב  WORDS ALONE CAN CHANGE A סוכה פסולה INTO A סוכה כשירה (2 examples) A 2 walled סוכה built in a מבוי one may consider the לחי  of the מבוי as a Mechitza  (3d wall) for theסוכה  on Shabbos Sukkos only. The reason is because of מיגו . Since it is considered a Mechitza for Shabbos it is also considered  a Mechitza for the סוכה. This 2 walled סוכה is kosher only on Shabbos and not in the weekdays. Someone being מקבל שבת early and doing so by saying מזמור שיר ליום השבת changes a non-kosher סוכה into a kosher one. O.Ch. 630 : 7   A סוכה, higher than 20 אמות is פסול. If you place straw etc. on the floor of the סוכה and thereby reducing the height, it is kosher, only if you are מבטל בפה the straw to the floor. You must verbalize & say, that you plan to keep the straw there O. Ch. 633 – 4
