Amen to that

Robert Beard, PhD Linguistics, taught language and linguistics at Bucknell University for 35 years. He calls himself "Dr. Goodword" and presides over his alphaDictionary site. He is a great source for all things about words. 

Here he explains hermeneutic.

hermeneutic / hêr-mê-nyu-tik / adjective, noun

Explanatory, clarifying, exegetical. Exegesis is usually reserved for explanations of the mundane world while hermeneutics is applied mostly in religion and philosophy.

Hermeneutic, Dr. Goodword writes, began as a term in the Church, referring to activities (or art) that explained the scriptures—even though it is based on the name of a pagan god, Hermes. The practice of interpreting the scriptures is known by the adjective used as a noun, hermeneutic (or hermeneutics), and someone involved in it is a hermeneutist. If we remember that this word is derived from the name of the Greek god Hermes, we will be less likely to replace the middle E with an A as many of us, unfortunately do.

Using the word: Since today's word originated in the Church, let's touch base there first: "I just came from another hermeneutic sermon on the epistle of St. John that missed the whole point of the chapter." Remember that, although today's Good Word has long since kicked the habit of the Church and waded into the general vocabulary, it still generally refers to a higher level of interpretation than its lay counterpart, exegesis: "Political science gives us a political hermeneutic of the world while history provides more of a philosophical one."

History: Hermeneutic is the English interpretation of Greek hermeneutikos "interpreting", the occupation of a hermeneutes "interpreter". This word was derived from hermeneuein "to interpret", a verb derived from the name of Hermes, the eloquent wing-footed messenger and interpreter of the ancient Greek gods. Exactly how his name turned up in hermetic, as in hermetically sealed, remains a mystery. This word was adopted in the Middle Ages by alchemists from the Latin word hermeticus, which at the time simply meant "related to Hermes".
