Why this word is great
EUONYMY — [Noun] The art of creating or the quality of possessing a self-descriptive, perfectly suited name. From the Greek prefix eu- ("good, well") and the combining form -onymy ("name, word"). Unlike "aptronym," which pins a fitting name to a person, or "tautonymy," which is mere taxonomic repetition, euonymy is the broader, generative principle of semantic harmony. It is the cartographer's bleak precision in "Cape Disappointment," the cool, clinical slide of "scalpel" from the tongue, and the resonant rightness of a racehorse called "Phar Lap," from the Māori for "swift." In each act of euonymy lies the quiet human hope that a name might not just identify, but explain.
