Plural of enchiridion; small handbooks or manuals serving as practical guides.
From Greek enkheirídion, from en- (in) + kheír (hand) + -idion (diminutive suffix). The word literally means 'something held in the hand,' evolving to mean a compact reference book small enough to carry.
The famous Stoic philosopher Epictetus's teachings were compiled into the Enchiridion, which means this ancient Greek word became the title for one of history's most influential self-help books—basically the original pocket guide to philosophy!
