There are two different types of gzeirah shava specific words were part of the mesorah but the pesukim used and / or the actual item that was derived from the gzeirah shava may not have been part of the mesorah. The content of the limud was part of the mesorah but not the words used in the gzeirah shava. Halichos Olam Shaar 4. See also Ramban sefer ...
I once asked a rebbi of mine this very question, in a different context. The Gemara in Kiddushin 14b discusses a Gezerah Shavah using the word שכיר, a word that is found a number of times in the sections of the Torah that deal with slaves/servants. Tosofos there, s. v. מוכר, takes the liberty of applying this Gezerah Shavah to other instances of the word in ...
As the other answers stated, the main difference between נבילה וטריפה is the טומאה. However, there are also other differences, such as אותו ואת בנו (see שמלה חדשה טו); in שלחן ערוך פב where ביצת טריפה is אסור but ביצת נבילה is not; and (lamely) someone who makes a vow נדר not to benefit from one but left the other alone. These are found all over שמלה חדשה ...
Nice question. Tosfos there deal with a similar question that I believe would answer yours, too: מה אחות אשה מיוחדת כו'. וא''ת מה לאחות אשה שכן בידו לרבות כדפריך בפ' הבא על יבמתו (לקמן דף נד. ושם) וי''ל דאהיקש דר' יונה דסוף שמעתין (דף ח.) סמיך According to Tosfos, this Gemara is working in tandem with the hekesh of R' Yona which specifically ...
As suggested in one of the comments, the Gemara is describing an exegetical rule, rather than a principle of erring to the side of stringency when in doubt. This understanding is supported by the gemara's alternative answer there: איבעית אימא הכא תרי איסורי והכא תרי איסורי ותרי מתרי ילפינן אבל הכא חדא איסורא ותרי מחדא לא ילפינן If you prefer, however, I ...
See the Minchas Chinuch mitzvah 32 after he lists all 39 melachos, right after Hotzaah, page 177 in the new editions, he goes into pikuach nephesh he says the Rambam and most poskim (according to the Kessef Mishna) hold it is dechuyah while Rabbeinu Meir brought in the Rosh say it Hutrah.
The Rambam never permitted cooking Nevelah meat with milk. He only permitted deriving benefit from the mixture. Cooking Nevelah meat with milk is still prohibited (Maachalot Asurot 9:6).
Tosfos agrees that boneh is assur min hatorah when it is not for yom tov. As such, there is a maris ayin to carry a ladder since an observer may very well suspect the ladder carrier of fixing a roof for a non yom tov need.
