Etymology: "Rhinencephala" is the plural of "rhinencephalon," the name for the part of the brain involved in processing smell. The singular was formed from two Greek elements: "rhin-," from "rhis," meaning "nose," and "encephalon," meaning "brain," literally "within the head." Put together, the name describes a brain region tied to the nose. Because the word is a technical coinage built from classical roots, the plural simply follows the Greek pattern, with "-a" marking the neuter plural ending that Greek nouns in "-on" take. Anatomists use it to refer to more than one such structure, or to the set of olfactory-related regions as a whole.
