Lists of three: when the rule of three turns into a formula
“Vibrant, diverse, and full of life.” Triplets sound finished, which is exactly why they multiply.
A writing guide from Plainhand
The rule of three is real. Three items feel complete in a way two don't and four drag. It's why “veni, vidi, vici” has lasted two thousand years. But a device that always sounds polished is easy to reach for without thinking, and when every description comes in threes, the rhythm becomes a formula readers can hear.
The weak third item
Automatic triplets usually contain at least one filler item: a word added because the sentence wanted a third beat, not because it had a third thing to say.
Before
The city was vibrant, full of life, and full of energy.
After
By five in the morning, the fruit sellers were already arguing over the best corner.
“Vibrant,” “full of life,” and “full of energy” are one idea said three times. A single concrete detail shows more than all three.
Stacked adjectives
Before
The report is clear, concise, and comprehensive.
After
The report fits on two pages and answers every question the board asked.
Three abstract adjectives describe how a thing should be judged without giving any evidence. A specific fact does the judging for the reader.
The test: delete one
Take out the weakest item. If the sentence loses nothing, the item wasn't earning its place. Then ask whether two items, or one precise one, says it better.
When a triplet is right
- When all three items are concrete and necessary. “She packed a flashlight, two days of water, and her father's compass” is a list of real things, each doing work.
- When it's an actual list. Ingredients, steps, and requirements come in whatever number they come in.
- For a deliberate climax. One triplet, placed at the peak of a paragraph, can land hard, as long as it's the only one nearby.
A note for students
The five-paragraph essay trains writers to state three reasons in the thesis. That structure is fine for organizing an argument, but it tends to leak into every sentence. Keep the three-part structure at the level of the essay, and let individual sentences take whatever shape fits.
Finding them in your draft
Look for commas followed by “and” or “or.” If a single paragraph has more than one three-part list, rework all but the strongest.
