     Surrounded by names like those, it was little wonder that he'd found himself suited to a career in euonymy. If only there had turned out to be more naming and less strenuous diplomacy involved in the job, it would have been perfect.

This term is similar to the term aptonymy, but whereas aptonymy refers to the coincidence of a name and the person who was given it, euonymy is used when the name is deliberately chosen to match the person or thing it is given to.
