Etymology: Entozoans are named for their habitat: the word is built from "entozoa", the plural of a Greek-derived coinage meaning "animals within", and the suffix "-an", which marks a member of a group. "Entozoa" itself combines the Greek "entos", meaning "within", with "zoa", the plural of "zoon", meaning "animal". So the word's core literally describes animals living inside other animals. The English form is an inherited scientific label rather than an everyday word, and it belongs to the same family as "entozoon", the singular. Because "-an" is attached to the plural stem "entozoa", the word is a plural noun in its own right, used to group these internal organisms together as a category.
