Malicious → It is formed from "mal-" (meaning bad or evil) and "-icious" (from Latin "-iciosus", meaning full of or characterized by). The word "malicious" describes someone or something that is characterized by a desire to cause harm or suffering, hence, bad or evil in intent.
Think of 'mal-' meaning bad, and '-icious' suggesting full of — so, someone malicious is full of bad intentions.
