A thorough Quranic study on the word "quran" gives us the actual meaning of this word in the Quranic text: it does not mean "Islamic Quran", or "Quran of Islam", as Muslims think, but it refers to another book, an Arabic lectionary. This Arabic lectionary was a selection of verses and texts from the "sacred scriptures" (i.e. the Torah, the gospels, and other texts) that had been translated from Aramaic and Hebrew for the first time into an Arabic book. Hence the insistence of the Qur'anic text on the "Arabicness" of the "quran" that it mentions so much.
We can then understand what is the Quran: it is mostly a collection of proclamations, exhortations, discourses that were uttered to an Arab audience in order to present them this Arabic Lectionary. Because this lectionary was made from verses of the "sacred scriptures", it was then presented as the word of the God, which led most readers of the Quran to confusions: confuse the "sacred scriptures" (i.e. the word of God) with the Arabic lectionary, confuse the Arabic lectionary with the Quran of Islam, and then, confuse the Quran of Islam with the word of God.
Which leads then to major issues: who was the preacher who "speaks" in the Quran? How did he get the Arabic lectionary? Who taught him? Who made the Arabic lectionary?
