Tricolon padding
Reflexively listing three near-synonyms where one word would do. Form imitating substance.
What it is
The triple-adjective tic: 'robust, scalable, and maintainable', 'clear, concise, and compelling', 'innovative, cutting-edge, and forward-thinking'. The three terms overlap heavily; the second and third add little.
Why models do it (first principles)
The rhetorical pattern of three (tricolon) is rewarded as 'rhythmic' and 'persuasive' in the training data — speeches, marketing copy, mission statements. The model has internalized 'lists of three feel complete'. It will reach for two more synonyms even when the first word said everything.
How to think about it
Form imitating substance. The tricolon evolved in rhetoric to balance three genuinely distinct ideas. Reduced to a habit, it becomes filler that performs precision while delivering redundancy. The model selects the second and third words because the slot demands a word, not because the word adds meaning.
Examples

Fix prompt
A list earns its length by carrying distinct ideas, not by completing a rhythm. Stacking near-synonyms performs precision while delivering redundancy. The second and third item add cadence but no information, and the reader pays attention to them only to discover there was nothing there. Prefer one specific word that names the actual quality you mean.
Watch for
Concrete phrasings this pattern usually shows up as. These are not part of the copyable prompt. The prompt teaches the principle so the model can recognize the move even when the exact phrasing differs. Use this list to self-audit your own writing or to test a model.
