The maleficent witch cast a dark spell over the village.
Maleficent → It is formed from "male-" (from Latin *malus*, meaning bad or evil) and "ficent" (from Latin *facere*, meaning to make or do). The word "maleficent" describes someone who does evil or bad things, thus meaning 'doing harm' or 'evil-doing'.
Think of 'male-' meaning bad and 'ficent' meaning to make — this helps you remember that maleficent refers to someone who does bad things.
