Is the Qur'an a book?

This may seem like a strange question at first, since well, we can literally see that the Qur'an is a book: And we often refer to it as a book. And the Qur'an refers to itself as a book (Qur'an 5:15 : "...There has come to you from Allah a light and a clear Book."). However, it doesn't seem that straightforward: - القرآن‎‎ al-Qurʾān means "the recitation" (Wikipedia ), which suggests the sequence of words in the Qur'an is what makes it the Qur'an, not the medium on which it's written, - the Qur'an was transmitted through "oral memorization and recitation" (see: https://islam.stackexchange.com/q/28370/17163) , i.e., the Qur'an existed before it was in book format, and - I have the Qur'an on my computer in pdf format; we don't likewise call the Qur'an e.g. the "holy pdf" of Islam. **Question**: Is it technically correct to refer to the Qur'an as a book? This is a bit of a philosophical question: identifying the essence of the Qur'an, that which if we took it away, we would no longer have a Qur'an. ---- *Update* (or: what I've learned since I first posted this question): - Another question highlights that the word *kitab* (کتاب‎), which means "book ", is used in Qur'an 2:2 to refer to itself https://islam.stackexchange.com/q/14927/17163 - III-AK-III writes the *Qur'an did not, does not, and will not rely on manuscripts* in an answer to https://islam.stackexchange.com/q/46748/17163 This answer quotes the ayah: > Rather, the Qur'an is distinct verses [preserved] within the breasts of those who have been given knowledge. And none reject Our verses except the wrongdoers. > Qur'an 29:49 - Wikipedia writes: When referring to the physical bound volume, some use the term *mus'haf* (مصحف‎).
