The word Bible comes from the Greek word "Biblos," which is translated "book." The original manuscripts of the Bible were kept in the synagogues. Those who had custody of the manuscripts first used the Greek word to describe the collection, which later became known as "the Book."

If by "Bible" you mean "a canonical collection of texts sacred in Judaism and Christianity" ---- this is the definition YOU quoted --- this is not the same word or meaning as "biblos."
The key word in the definition of "Bible" is "canonical." The Jews had a number of different accepted lists, some of which included only the Pentateuch, some of which were in LXX Greek and included such books as Tobit, Judith, Wisdom, Sirach, 1 and 2 Maccabees (this was the collection used by Jesus and quoted by the Apostolic-era writers of the New Testament); some of the Jewish collections even included 3 and 4 Maccabees, Enoch, Jubilees, and other now-excluded texts.
The Jewish Canon adopted by Protestants at the time of the Reformation, the Masoretic Text, is now considered the authoritative Hebrew text; however, it was not finalized until the 9th century A.D.
So, as for "canonical"? The word "biblos" in the Scriptures never refers exclusively to the collection of Jewish (or Christian) canonical texts. Its meaning is much wider and much vaguer: it means, simply, "the books."
The word "Bible" -- or ANY related word meaning a "collection of canonical texts" --- is not found in the Bible.
A person persistent about clarifying the accurate definitions, should not be accused of "twisting words."
