Part of speech: adjective

Definitions

1. Characterized by having rearward-facing grooved fangs typically found in certain snakes that help in delivering venom while chewing prey
2. Denoting a type of dentition where enlarged, grooved teeth situated at the back of the mouth function in venom injection in some reptilian species
3. Describing a morphological feature involving posteriorly positioned fangs with a groove, used by specific snakes to subdue prey through venom delivery

Etymology: "Opisthoglyphous" is a technical term from herpetology, built from two Greek roots. "Opisthen" means "behind" or "at the back," and "glyphe" means "carving" or "groove." Put together, an "opisthoglyph" is a snake whose grooved fangs sit toward the rear of the mouth, rather than at the front as in vipers and cobras. The adjective is formed by adding the English suffix "-ous," which turns a noun into a descriptive word meaning "having the quality of" or "characterized by." The word is a modern scientific coinage, not an ancient one. Ancient Greeks had the separate roots but no reason to combine them into a term for snake anatomy. Its value lies in precision: the name tells you exactly where on the jaw the venom-conducting groove is located, which matters because rear-fanged snakes often need to chew on prey to get venom flowing.
