The מלאכה of כותב (writing) on שבת: what counts as liable writing, which materials and surfaces qualify, and which cases are exempt

Overview

The משנה sets the basic rule for the מלאכה of כותב on שבת: writing two letters in one הֶעְלֵם makes a person חייב. It lists inks and surfaces that count, rules on writing on or scratching into the skin, and gives a long list of exempt cases. These include writing that does not last, writing in an unusual way, writing that is not a new two-letter text, and letters that are not read together. The גמרא defines the five inks and explains that 'anything that makes a mark' covers every lasting material valid for a גט. It brings רבי אליעזר's proof about scratching on skin from בן סטדא, which the חכמים reject, followed by a short side discussion about that name. It then shows that two exempt cases in the משנה go against רבי אליעזר and רבי יהודה. It also discusses a single letter that completes a ספר, and רבי אמי's ruling that letters written in two cities make one חייב. The amud ends with a ברייתא about correcting one letter, explained by רב ששת and רבא, and opens a new ברייתא that continues on the next amud.
