Root Explanation

Parasitological → It is formed from "parasite" (from Greek "parasitos", meaning one who eats at another's table) and "-logy" (from Greek "logia", meaning study of). The word "parasitological" refers to the study of parasites and their relationships with their hosts.

Memory Tip

Think of studying the "parasite" (someone who lives off others) and how that connects to the "-logy" (study) of these organisms.
