- Reshima is a toldah of koseiv and refers of making symbols instead of letters.
- Writing on one’s skin is considered koseiv, as is engraving. However, scratching is not considered koseiv.
- Most electronic writing is not considered miskayeim and patur. However, certain e-readers keep the text even without electronic current, and would be considered miskayeim.
We are continuing in an introduction to Klal 37, the melacha of koseiv. In the previous shiur, we learned that combining letters to create words is not koseiv, because the melacha of koseiv is specifically creating the letters. However, there is a way to create letters which would mistakenly be excluded based on that definition. If a person has two half-letters (eg, letter “a” cut in the middle) it is koseiv to put those two halves together on Shabbos. A practical example would be if the page of a siddur is torn through the middle of the letters. Aligning the parts of the page in order to read it would be considered koseiv. Since it does not have permanence, it is not assur mideoraysa, but nevertheless it will be assur miderabanan.
This point was actually presented as a shaila to the Rema. If there is writing on the side of a sefer, when the sefer is opened, it breaks the letters (which would be mocheik), and when the sefer is closed, it creates the letters, which should be koseiv. The Rema responded that he feels it is not assur, similar to the reason why opening and closing a door is not considered boneh and soseir. Since part of the function of the door is for it to open and close, it is considered part of the function of the door rather than building or destroying the wall around it. Similarly, since the function of the sefer is to open and close it, it is muttar.
Other poskim disagree with the comparison. They understand that the use of a door is part of the nature of the building to which the door is connected. The writing on the side of the sefer is not part of the nature of the sefer, but happens to be there. The Mishnah Berurah concludes that it is preferable not to use such a sefer, but in a situation of need, one can rely on the opinion that it is not koseiv.
The Chayei Adam will address the use of pre-formed letters in siman 6.
A toldah of koseiv is making a picture. The same way that letters represent sounds and ideas, markings which are a representation are a toldah of koseiv. If so, assembling a jigsaw puzzle would fall under this toldah. We will discuss children’s puzzles in the upcoming shiur, be’ezras Hashem.
Summary
- The melacha of koseiv is specifically forming letters. This includes taking a printed or pre-formed letter which is currently in two pieces and putting the two pieces together, such as aligning the page of a torn siddur.
- There is a question whether it is muttar to use a sefer which has writing on its side that will separate every time it is opened. It is preferable not to use such a sefer but one may do so, if necessary.
- A toldah of koseiv is making a picture.
- The melacha of koseiv is the issur of writing and creating letters.
- The shiur deoraysa is writing two letters, even if not on the same page.
- The two letters can be written both through active writing and through erasure.
- The writing needs to have kiyum, some amount of permanence.
- Although the shiur is two letters, chatzi shiur is assur.
- Cutting pills. We learned that the reason mechateich does not apply to food is because the chashivus of cutting something is to use it for a future, significant action. Therefore, the concept does not apply to food, which is cut and then immediately eaten. Rav Shlomo Zalman extends this idea to cutting pills. A person who needs to take medication on Shabbos, but it is not life-threatening, can cut the pill, because it is immediately consumed (Shemiras Shabbos Kehilchasa).
- Toilet paper. If a person does not have precut toilet paper or tissues, they will encounter the issur of mechateich when they cut it to a specific size, and koreiah fire just cutting in general. It is important to understand that for kavod habriyos, the need for a person to cut themselves, Chazal lifted many of their issurim. For example, although amira l’achum in this case would be amira on an issur deoraysa, which is generally never permitted, Chazal permit it in this case. So one suggestion is that they can ask a non-Jew to cut the toilet paper.
- There is a discussion whether it is muttar to cut pills on Shabbos or not; one should ask their rav
- Regarding cutting toilet paper, one suggestion is to instruct a non-Jew to cut it. We will discuss toilet paper further in the upcoming shiur, be’ezras Hashem.
