Masticator → It is formed from "masticare" (meaning to chew) and "-or" (meaning one who). The word "masticator" refers to one who chews, particularly in the context of the mouth's function in breaking down food.
Think of someone who is 'chewing' ('masticare') — that's why a masticator is someone who chews.
