The word was coined by William Kirby and William Spence in their Introduction to Entomology in the early 1800s: "In the terminology, or what, to avoid the barbarism of a word compounded of Latin and Greek, [Kirby and Spence] would beg to call orismology of the science, they have endeavoured to introduce throughout a greater degree of precision and concinnity" in the terms used to talk about insects.
The term was first proposed by William Kirby and William Spence in their work on entomology in the early 1800s, with the goal of creating a more organized and precise vocabulary for insect study.
