Have you ever been asked to explain something you know really well, only to find yourself stumbling through the explanation?
You understand the subject. You've worked with it, studied it or spent enough time thinking about it that it makes perfect sense in your head.
But the moment somebody asks you to explain it, everything becomes more complicated.
You start in the middle. Then realise you should have explained something earlier. You add another example, go back to your original point and eventually notice that the other person looks more confused than when you started.
It's frustrating, particularly when you know you understand what you're talking about.
If this sounds familiar, there are some excellent books to explain things clearly that can help you organise your knowledge, simplify complicated ideas and communicate in a way other people can follow.
Here are five worth exploring.
Why Knowing Something Doesn't Always Mean You Can Explain It
Understanding a subject and explaining it are two different skills.
When you're familiar with something, your brain has already made connections between the ideas involved. You understand the background, the terminology and the details that make everything fit together.
But somebody hearing your explanation for the first time doesn't have those connections.
They need a starting point.
They need to understand why the subject matters before being introduced to everything that makes it complicated.
And they need information presented in an order that makes sense to them.
That's where clear communication becomes so valuable.
The following books approach this challenge from different directions.
1. The Art of Explanation — Lee LeFever
Best for making complicated subjects easier to understand.
The Art of Explanation focuses on helping people communicate ideas to audiences who may not share their knowledge or experience.
One of its most useful themes is recognising the gap between what you know and what your listener knows.
Imagine explaining a new computer system to somebody who has never used it.
You could begin by describing the features, technical requirements and different functions.
Or you could start with something much simpler:
"This system helps us keep all our customer information in one place."
Now the person understands the purpose.
The details can come afterwards.
That's an important distinction. A good explanation doesn't necessarily begin with the most impressive information.
It begins with the information the listener needs.
Something to try: Before explaining a complicated subject, ask yourself, "What does this person need to understand first?"
Start there rather than jumping straight into the details.
2. Made to Stick — Chip Heath and Dan Heath
Best for making your ideas easier to remember.
Have you ever listened to an explanation that made sense at the time but disappeared from your memory almost immediately?
Sometimes the problem isn't understanding the words.
It's that the explanation doesn't give us anything memorable to hold on to.
Made to Stick explores why certain ideas stay with people while others are quickly forgotten.
The authors discuss principles including simplicity, concreteness and storytelling.
These can be particularly helpful when explaining something that feels abstract.
For example, imagine telling a colleague:
"We need to improve the efficiency of our communication processes."
Now compare that with:
"We're spending too much time searching through emails for information that should be easy to find."
The second explanation gives the listener a specific problem to picture.
It also makes the purpose of the conversation easier to understand.
Something to try: When explaining an abstract idea, look for a concrete example from everyday life.
Sometimes one familiar example communicates more effectively than several minutes of general explanation.
3. The Pyramid Principle — Barbara Minto
Best for organising your thoughts before you speak.
One reason explanations become confusing is that we often describe things in the order they occurred to us.
But the order in which we think about something isn't always the best order for explaining it.
The Pyramid Principle introduces a structured approach to organising information, with the main message supported by logically grouped ideas.
This is especially useful in workplace communication.
Imagine your manager asks why a project is running behind schedule.
You could spend five minutes explaining everything that happened during the previous month.
Or you could begin with:
"The project is delayed because two important approvals are still outstanding."
Then explain the supporting details.
The second approach gives the listener a clear understanding of the situation before introducing the background.
Something to try: Before explaining something important, identify your main conclusion.
Then organise your explanation around three simple questions:
What's the main point?
Why does it matter?
What information supports it?
You don't need to make every conversation formal. You're simply giving your thoughts a clearer direction.
4. Simply Said — Jay Sullivan
Best for communicating effectively in everyday professional situations.
Sometimes an explanation is technically correct but still doesn't connect with the person listening.
Perhaps you're providing too much detail.
Perhaps you're using language that feels natural to you but unfamiliar to somebody else.
Or perhaps you're concentrating so much on delivering your explanation that you forget to notice whether it's being understood.
Simply Said explores practical communication skills for professional situations, including conversations, presentations and written communication.
A valuable lesson is that communication should be shaped around the audience.
That means considering what the other person needs from the conversation.
Someone asking for a quick update probably doesn't need the same level of detail as somebody learning an entire process.
Something to try: When somebody asks you to explain something, consider how much detail they actually need.
You might begin with a short explanation and then ask:
"Would you like me to go into more detail?"
This gives the listener some control over the conversation and helps prevent unnecessary information from getting in the way.
5. Articulate — Julian Merren
Best for turning clear thoughts into clear spoken explanations.
There's another difficulty that can arise even when you understand your subject and know what the listener needs.
You simply struggle to get the words out in the right order.
Your thoughts arrive faster than you can organise them.
You begin explaining one point, remember something else halfway through and suddenly find yourself heading in a different direction.
Articulate: How to Express Yourself Clearly and Confidently by Julian Merren focuses on practical ways to close that gap between thinking and speaking.
The book explores organising your thoughts, finding the right words, reducing rambling and communicating with greater clarity and confidence.
One useful approach is:
Pause. Point. Explain.
Pause briefly before answering.
Identify the main point you want to make.
Then explain it using the details that genuinely help the listener understand.
Imagine somebody asks why you think a proposed change won't work.
Instead of immediately listing every concern, you might begin with:
"I think the idea has potential, but the current deadline is unrealistic."
Now the listener understands your position.
You can explain the reasons afterwards.
The aim isn't to make every sentence perfect.
It's to give your explanation a clear starting point.
If you often know exactly what you mean but struggle to express it aloud, you can discover Articulate by Julian Merren.
A Simple Exercise to Help You Explain Almost Anything
Here's something you can practise without needing an audience.
Choose a subject you know reasonably well.
It might be something connected to your job, a hobby or even a process you use every day.
Now try explaining it in three different ways.
First: Explain it in one sentence
Focus entirely on the main idea.
Don't worry about background information or supporting details.
Next: Explain it in thirty seconds
Add a little context.
Explain why it matters and include one example if it helps.
Finally: Explain it in two minutes
Now expand your explanation with relevant details.
The important part is noticing what changes between the three versions.
You're practising how to adjust the amount of information you provide without losing the central meaning.
And that's a skill that becomes useful in all sorts of conversations.
Remember That More Detail Doesn't Always Mean More Clarity
When somebody doesn't understand our explanation, our first instinct is often to say more.
We repeat ourselves.
We introduce another example.
We explain the background again.
But sometimes the problem isn't a lack of information.
It's that the main idea has become buried underneath everything else.
The next time somebody looks confused, resist the urge to immediately repeat your entire explanation.
Instead, ask which part needs clarification.
You might discover that they understood almost everything and were uncertain about just one detail.
Good communication isn't simply about delivering information.
It's about helping somebody else make sense of it.
Final Thoughts
If you know your subject but struggle to explain it, don't assume you need more knowledge.
You may simply need a better way to organise and communicate what you already understand.
These books to explain things clearly offer different approaches, from simplifying complicated subjects and making ideas memorable to organising information and speaking with greater confidence.
Choose the one that addresses your biggest difficulty.
And remember, you don't need to explain everything you know in order to explain something well.
Start with what matters. Make your point clear. Then add the details that help.
If expressing your thoughts aloud is the part you find most difficult, Articulate by Julian Merren is a useful place to continue exploring.
Because the goal isn't to sound more complicated.
It's to be understood.
