Protozoologist → It is formed from "proto-" (from Greek "protos", meaning first) and "zoologist" (from Greek "zōion", meaning animal, and "logia", meaning study). The word refers to a scientist who studies the first or simplest forms of animal life, specifically protozoa.
Think of 'first' ('proto-') and 'study of animals' ('zoologist') to remember that a protozoologist studies the simplest forms of animal life.
