Command Words Glossary

What are Command Words?

Command words are specific terms used in exam questions that tell you what the examiner expects from your answer. These words guide you on how to approach the question, whether it's to describe something, explain a concept, or evaluate a situation.

Why are Command Words Important for Exams?

• Clarify What's Being Asked: Command words tell you exactly what to do. For example, "Describe" asks for details, while "Evaluate" asks you to judge or assess something.
• Structure Your Answer: They help you decide the structure of your response. For example, "Compare" means you'll need to discuss both similarities and differences.
• Get Full Marks: Understanding and responding to command words correctly ensures you answer in the way the examiners expect, increasing your chances of gaining full marks.
• Save Time: Knowing what the command words mean helps you focus directly on what's needed, saving time in the exam.
