The Mishnah is supposedly THE codex of the Jewish Law. I'm trying to understand the purpose of the questions in the Mishnah. It appears to be gratuitous as it adds no information.
Compare the original Mishnah (Berachot 1:1):
"מֵאֵימָתַי קוֹרִין אֶת שְׁמַע בְּעַרְבִית? מִשָּׁעָה שֶׁהַכֹּהֲנִים נִכְנָסִים לֶאֱכֹל בִּתְרוּמָתָן, ..."
"From when may one recite Shema in the evening? From the time when the Kohanim go in to eat their Terumah ..."
Vs a "normalized" version:
"קוֹרִין אֶת שְׁמַע בְּעַרְבִית מִשָּׁעָה שֶׁהַכֹּהֲנִים נִכְנָסִים לֶאֱכֹל בִּתְרוּמָתָן..."
"One may recite Shema in the evening from the time when the Kohanim go in to eat their Terumah..."
The use of questions throughout the Mishnah seems inconsistent, e.g. not every Mishnah starts with a question.
I've heard a couple of speculations, like: "so it can be remembered better", or "they wrote exactly what the Rabbi said" but for a legal document that defines the principles of Judaism it sounds "unprofessional" (to me at least).
Is there a [non circumstantial] reason for this phenomenon?
