Similar to idolatry and iconodulism, epeolatry literally means the worship of words. It derives from epos, which unlike logos more specifically means word in Greek, and was apparently coined in 1860 by Oliver Wendell Holmes, Sr.Figuratively speaking, the word can be playfully applied to philologists, linguists, or lexicographers.
The term is of significant satirical value and may be used in the denigration of popular religions or belief systems. For example, one could call Christianity an epeolatric religion because the majority of its teachings hinge on the words of the Hebrew Bible. However, you are unlikely to encounter the word in any form because it remains obscure.
"I read my dictionary for a few more minutes, until tiredness eventually brought my epeolatry to an end for the day."
