The letter ת that is added to the beginning of a word to indicate that it is a noun usually teaches about the quantity or the quality. When the noun that has in it a sign that it is a noun and the extra letter נ is added (like תופיני), it sometimes comes to diminish the theme. And the sages of blessed memory observe in the word תופיני (broken pieces)¹⁵ two meanings.

footnotes: ¹⁵ Leviticus 6:14.

And we find that the letter נ when it is added to the noun expands the theme – שבתון (sabbatical), עצבון (sorrow), according to the sages of blessed memory.

When the second and third radicals repeat, it teaches that the matter is strengthened, like ירקרק (greenish) and אדמדם (reddish).

Rabbi Yehuda interprets תופיני to mean they shall be baked when they are still beautiful, while Rabbi Yossi interprets תופיני to mean they should be baked extensively, i.e., more than once¹⁶.
