Write to Explain
When your purpose is to explain, you are giving your reader a tour. A good guide never skips a stop, and when the stops are causes and effects, never breaks the chain.
Every explanation is a trip you take your reader on. When you explain why something happens, the trip runs along a chain: each stop is caused by the one before it. Here is what a good one carries, and what each part does for the reader.
- A clear destinationYour topic, in one sentence the reader cannot misunderstand. They should know exactly where this tour is going before it starts, and that a chain of cause and effect is how it gets there.
- Stops in the right orderYour causes and effects, at least three, in the order that helps the reader most. In a cause-and-effect explanation the order is not a matter of taste: each effect becomes the cause of the next, so a good guide never doubles back.
- What to notice at each stopFor each stop, one more line: name the cause, name the effect it produces, and make the link between them plain. The noticing is what makes it a chain and not a bare list.
- An ending that leaves them knowing the wayWrap it up and remind the reader of the whole chain, from the first cause to the last effect. They should walk away able to trace it themselves.
