When we think about exam preparation, we often focus on revising content, whether that’s spending time learning facts, memorising formulas, or practising questions. While all of this is important, there’s another skill that can have a huge impact on exam performance and is sometimes overlooked: understanding command words.
Most students will recognise command words when they see them. Words such as define, explain, analyse, and evaluate appear regularly in written exams across a wide range of subjects. The challenge is that recognising these words isn’t the same as fully understanding what they’re asking you to do.
Many students lose marks not because they don’t know the answer, but because they answer a different question from the one the examiner has asked. You might write a detailed explanation when only a brief definition is needed, wasting valuable time in an exam, or you might describe something when the question is asking for analysis. In both cases, important marks can be missed.
Learning how to respond to command words is one of the simplest ways to improve exam technique. Once you understand exactly what each command word is asking for, you can approach questions more confidently as you’ll know the structure to follow and the content to include. This blog explores some of the most common command words and explains what examiners are looking for when they use them.
Why command words matter
Examiners use command words to tell you precisely what kind of answer they want. They act as instructions that guide you towards the skills that are being assessed, whether that’s recalling knowledge, explaining a process, analysing evidence, or making a judgement.
Imagine being given directions to a destination. If you misunderstand the instructions, you may still travel a long distance, but you could end up in the wrong place. The same thing can happen in an exam. You might write a long answer filled with accurate information, but if it doesn’t match the command word, you’re unlikely to receive all the marks available.
The good news is that command words reappear across different subjects, so once you become familiar with them, you can apply the same skills across multiple areas of study. A useful way to think about command words is to group them according to the type of thinking they require.
Command words that test recall
Command words that test recall usually appear in questions that assess your ability to recall and communicate information accurately.
1. Define
When a question asks you to define something, the examiner wants the precise meaning of a word, concept, or term. A common mistake is to write far more than is necessary. Definitions are usually short and to the point. The focus is on accuracy rather than detail.
What the examiner is looking for:
Clear and precise meaning
Correct subject terminology
A concise answer
Example question (GCSE chemistry)
Define the term ionic bond. [1 mark]
Example answer
An ionic bond is the electrostatic force of attraction between a positively charged metal ion and a negatively charged non-metal ion.
2. Identify, state, or name
Questions that use the command words identify, state, or name usually require a very short response, not an explanation or description. Often they can be answered with a single word or phrase. Students sometimes overcomplicate these questions by writing more than is required, but you should trust the command word. If the examiner only asks you to identify a term, a single word may be enough.
What the examiner is looking for:
Selection of the correct information
A brief response
Example question (GCSE biology)
Identify the cell organelle where aerobic respiration takes place. [1 mark]
Example answer
Mitochondria.
3. Describe
The command word describe appears frequently across many subjects, but students often confuse it with explain. When you describe something, your job is to tell the examiner what happens, what something looks like, or what its main features are. You’re also being asked to present information clearly and logically.
Describe questions focus on giving an in-depth account of a fact, event, or process. You’re being asked to provide the ‘what, where, and when’, but not the ‘why’, which is necessary for explain questions. A good description paints a picture for the examiner. It focuses on what’s happening without moving into detailed reasoning.
What the examiner is looking for:
Clear factual details
Logical sequencing where appropriate
Relevant and accurate information linked to the question
No justification needed
Example question (GCSE geography)
Describe how global atmospheric circulation creates areas of high pressure. [3 marks]
Example answer
Air warms at the equator, becomes less dense, and rises. As it moves towards 30° north and south, it cools and becomes denser. The cooler air sinks towards the earth's surface, creating areas of high pressure.
4. Explain
The command word explain is one of the most common in exams. When explaining, you need to show understanding. The examiner wants more than a statement of facts. They want to know the reasons behind something happening. Words such as ‘because’, ‘therefore’, ‘as a result’ and ‘due to’ often help build strong explanations.
What the examiner is looking for:
Reasons and causes
Logical links
Evidence of understanding
Example question (GCSE geography)
Explain how a waterfall is formed. [4 marks]
Example answer
A waterfall forms when a river flows over layers of hard and soft rock. The softer rock erodes more quickly through hydraulic action and abrasion, creating a step in the river. Continued erosion forms a plunge pool beneath the waterfall. Over time, the hard rock above becomes unsupported and collapses, causing the waterfall to retreat upstream.
5. Analyse
Many students find analysis challenging because it requires deeper thinking than description. When you analyse something, you break it down into its component parts and explore how those parts work together. In English, analysis often focuses on how writers use language, structure, and literary techniques to create meaning. In other subjects, it may involve examining data, trends, or causes. Analysis explores different factors and considers how they influence the outcome.
What the examiner is looking for:
Connections between ideas
Patterns and relationships
Conclusions supported by evidence
Example question (GCSE geography)
Analyse how urbanisation can affect quality of life in a city. [3 marks]
Example answer
Urbanisation can improve quality of life by creating more jobs and increasing access to services such as healthcare and education. However, rapid urban growth can lead to overcrowding and increased pollution, which can negatively affect people's living conditions. This means the impact of urbanisation depends on how well the city manages its growth.
6. Compare
Questions that ask you to compare require you to examine more than one thing and discuss the relationship between them. One of the most common mistakes is focusing only on similarities or differences. Strong comparison answers usually include both.
What the examiner is looking for:
Similarities
Differences
Clear links between the things being compared
Example question (GCSE biology)
Compare aerobic and anaerobic respiration. [4 marks]
Example answer
Aerobic respiration uses oxygen and releases a large amount of energy, producing carbon dioxide and water. By comparison, anaerobic respiration takes place without oxygen and releases less energy, producing lactic acid in animals. Both processes release energy from glucose, although aerobic respiration is more efficient.
Command words that require judgement
At the highest levels, examiners often want students to think critically and form balanced conclusions.
7. Evaluate
Evaluation involves making a supported, reasoned judgement about something's effectiveness, value, or success. To do this well, you need to consider different aspects of an issue before reaching a conclusion corroborated by evidence. Many students make the mistake of presenting only positive or only negative points. Evaluation is strongest when it carefully weighs the strengths and weaknesses of a topic and demonstrates balance.
What the examiner is looking for:
Consideration of different factors or perspectives
Evidence supporting points
A justified conclusion
Example question (GCSE chemistry)
Evaluate the use of electrolysis to produce hydrogen. [3 marks]
Example answer
Electrolysis can produce very pure hydrogen, making it useful for certain industrial processes. However, it requires significant amounts of electricity, which can make it expensive. Therefore, electrolysis is a good method when high-purity hydrogen is needed, but it may not be the best option when keeping costs low is important.
8. Discuss
The command word discuss asks students to explore an issue from more than one perspective and offer a considered, balanced view that’s backed by evidence. Discussion questions often appear in subjects where there may be different opinions or competing arguments. The aim is to demonstrate understanding of the wider issues rather than simply presenting a single viewpoint.
What the examiner is looking for:
Exploration of multiple perspectives
Weighing up different arguments
Backing your points with evidence and examples
A thoughtful conclusion where appropriate
Example question
Discuss the use of hydrogen as a fuel. [4 marks]
Example answer
Hydrogen is often viewed as an environmentally friendly fuel because it only produces water when used. It could also help reduce reliance on fossil fuels. However, hydrogen can be expensive to produce, and storing it safely can be difficult. Although hydrogen offers environmental benefits, these practical challenges may limit its widespread use in the short term.
Common mistakes students make
Even students who know the content well can lose marks when they misinterpret command words. One common issue is writing too much for simple recall questions that are only worth one mark. Another issue is confusing description with explanation. A student may describe a process accurately but fail to explain why it happens. In that situation, valuable marks may be lost.
In comparison questions, a common mistake is for students to write separate descriptions of each item without making direct links between them. Examiners are looking for clear similarities and differences, so it’s important to compare the two throughout your answer rather than discussing them independently.
Students can also lose marks in evaluation questions by presenting only one side of an argument or failing to reach a clear judgement. Evaluation requires you to consider different factors and make a reasoned conclusion based on the evidence you’ve discussed. In analysis questions, students sometimes identify information without exploring its significance. Analysis requires you to look beyond what’s happening and consider why it matters or what impact it has.
Another mistake is giving answers that are too general. Many command words require subject-specific knowledge and terminology, so vague responses often miss opportunities to gain marks. Some students also avoid making a judgement in evaluation questions because they worry about being wrong.
In reality, examiners often want to see a coherent conclusion. As long as it’s supported by evidence, a well-justified judgement is usually rewarded. The more exposure you have to exam questions, the easier it becomes to recognise exactly what each command word requires.
How to practise command words effectively
The best way to improve your understanding of command words is through regular exam practice. As you work through past papers, take a moment before answering each question. Look carefully at the command word and ask yourself what skill is being assessed. You could even create a revision sheet containing common command words and a brief explanation of what each one means. In time, these instructions will become second nature.
When reviewing marked work, pay close attention to your teacher or tutor’s comments. If marks were lost, consider whether the issue was a lack of knowledge or a misunderstanding of the command word. Often, recognising this difference can help you make immediate improvements.
Understanding the question is half the battle
It’s easy to underestimate the importance of command words. They’re a small part of a question, but they have a huge influence on the quality of your answer, and understanding them is a crucial part of improving your exam technique. Command words signpost you to exactly what the examiner expects you to focus on in your answer. They allow you to structure your response more effectively and make better use of your time in an exam.
The more familiar you become with command words, the more confident you’ll feel when facing exam questions. Strong subject knowledge will always matter, but knowing how to communicate that knowledge is just as important. By learning to recognise and respond to command words, you give yourself the best possible chance to show examiners what you know and achieve the grade you’re capable of achieving.
