Malformation → It is formed from "mal-" (meaning bad or ill) and "formatio" (from Latin, meaning formation or shaping). The word "malformation" refers to a bad or abnormal formation of something, often used in a medical context to describe physical deformities.
Think of 'mal-' meaning bad and 'formatio' meaning shaping — this helps you remember that malformation refers to a bad or abnormal shaping.
