malo
/ˈmalo/ · A1 · adj
bad, evil, mean
👿 mal- = bad, as in malfunction, malice, malware; malo is that root as a word
From Latin malus (bad). English kept it as the prefix mal-: malfunction, malnutrition, malicious, dismal. Spanish kept it as a full adjective, and el malo is the villain of a story, which stretches to the devil.
