A person who shows great admiration or devotion to books, especially the Bible, often to an excessive degree.
As a bibliolater, she spent hours reading and discussing the Bible with others.
Bibliolater is formed from "biblion" (from Greek "biblion", meaning book) and "-later" (from Latin "latreia", meaning worship or service). The word describes someone who worships or has an excessive reverence for books, particularly the Bible.
Think of 'biblion' meaning book and 'latreia' meaning worship — this helps you remember that a bibliolater is someone who worships books.
