If you practice verbolatry, you'll probably be able to figure out what the word itself means: a love of words and grammar.
For word worshipers, the noun verbolatry is nearly perfect. It's an uncommon word for an uncommon condition, the adoration of language and the words and rules that comprise it. The roots of verbolatry combine the Latin word verbum, which means "word," and the suffix -latry, which means "worship of" and comes from the Greek latreia, "service paid to the gods." If you worship at the church of grammar, you've got a full-fledged case of verbolatry.
