People assume clear explanation requires a big vocabulary. The opposite is true — the clearest explanations use small words in a good order.
Start with the outcome
Say what it does before you say how it works. Most people explain in the order they learned it, which is rarely the order that helps a listener.
- Weak: "It uses a queue-based retry mechanism with exponential backoff…"
- Better: "It makes sure no order gets lost if the payment system is briefly down. The way it does that is…"
One idea per sentence
Long sentences with three clauses are where listeners fall off. Break them.
Use a comparison
An analogy from ordinary life carries a technical idea a long way.
- "Think of it like a waiting room — people are seen in order, and nobody is turned away."
- "It's the same idea as a spare tyre."
Signal the structure
Tell the listener where you are.
- "There are three parts to this."
- "That's the first bit. The second is…"
- "This is the part that matters most."
Check, but not with "do you understand?"
That question puts the burden on the listener to admit confusion, and most will say yes regardless. Ask differently:
- "Does that match what you were expecting?"
- "Which part should I go over again?"
- "How would you explain this to your team?"
"Which part should I go over again?" assumes something needs repeating, which makes it safe to say so.
Stop when you are done
Adding more detail after the listener has understood makes the explanation worse, not better.
