Bibliolater is a noun that refers to one who is excessively devoted to books.
You may recognize the word ‘bible’ in bibliolater. That’s because both words come from the Greek biblion (BEE bee yon) meaning ‘book.’ In addition to referring to a person highly devoted to books, our word of the day may also describe someone with an excessive reverence to the letter of the Bible.
My son is quite a bibliolater. I’ve seen him read as many as three books a week.
