In rhetoric, eunoia (Ancient Greek: εὔνοιᾰ, romanized: eúnoia, lit. 'well mind; beautiful thinking')[1] is the good will that speakers cultivate between themselves and their audiences, a condition of receptivity.[2] In Book VIII of the Nicomachean Ethics, Aristotle uses the term to refer to the kind and benevolent feelings of good will a spouse has which form the basis for the ethical foundation of human life.[3] Cicero translates εὔνοιᾰ with the Latin word benevolentia.[4]
It is also a rarely used medical term referring to a state of normal mental health.[5] Eunoia is the shortest English word containing all five main vowel graphemes.[1]
