EUPHONY, in Grammar, an easiness, smoothness, and elegance of pronunciation. The word is formed of eu, bene, "well;" and phōnē, vox, "voice." Quintilian calls euphonía, "vocalitas;" Scaliger, "facilis pronuntiatio."
Euphonía is properly a kind of figure whereby we suppress a too harsh letter, or convert it into a smoother, contrary to the ordinary rules. There are examples enough in all languages.
