erev yom kipur 5759,
shalom uberacha, gmar hatima tova.
bamishna neemar ... aval lo kevuchin velo shelukim... rashi omer shelukim:
mevushalim harbe meod... mevushalim : kederech bichul.
lama hamishna tsericha lelamed oti shelukim?
im mevushalim assurim kal vachomer shelukim. ( mevushalim harbe)
[Translation: The Mishnah says that one does not fulfill his obligation to eat Maror by eating vegetables which are "Kevushin," "Shelukin," or "Mevushalin." Rashi says that "Shelukin" are vegetables that have been "cooked a lot" -- "Mevushalin Harbeh." Why, then, does the Mishnah say "Shelukin" if it already mentioned "Mevushalin?" If one is not Yotzei with cooked vegetables, then certainly one is not Yotzei with very cooked vegetables!]
She'eila Tovah. Ha'teshuvah ha'peshutah hi sheha'Mishnah "Lo Zu Af Zu Ketani": Zot omeret, lo rak she'ein adam Yotzei im Shelukin, she'hem mevushalin harbeh, ela afilu im Mevushalim k'darko ein adam Yotzei Yedei Chovaso -- v'Chen kasvu ha'Tosfos (39b, DH Lo)
[Translation: Good question. The simple approach is that the Mishnah means "Lo Zu Af Zu Ketani" -- "not only this (Shelukin), but even this (Mevushalin) is invalid" This is the way TOSFOS (39b, DH Lo) understands the Mishnah.]
