Rule 9.1: Use a different sentence construction when a word-for-word replacement is not enough
When a non-approved word cannot simply be swapped for an approved word with the same part of speech and the same meaning, do not force a literal word-for-word replacement. Instead, restructure the whole sentence using approved words so it preserves the original meaning clearly and grammatically.
What a checker looks for
Usually a deviation, and context can excuse it.
- Flag a sentence where a non-approved word's dictionary alternative has a different part of speech or would create a grammatically awkward or leftover structure if substituted in place (e.g. an adjective's approved verb replacement left inside an unchanged 'must be ...' construction).
- Flag a sentence where a word-for-word substitution would produce a meaningless or nonsensical result (e.g. replacing a verb with its only listed dictionary alternative when that alternative has an unrelated sense in this context).
- Flag a sentence where the chosen approved substitute changes the intended meaning of the original word (e.g. substituting 'immediately' for 'just' in a restrictive sense).
- Flag a sentence containing a word that is not in the STE dictionary at all and that has not been reworded around an approved synonym or paraphrase.
What this rule does not cover
- A straightforward word-for-word substitution is compliant, not a violation of this rule, when the replacement has the same part of speech and preserves the exact meaning — this rule applies only when that simple substitution is not sufficient.
How to fix it
Determine the precise intended meaning of the non-approved word in context, then rebuild the sentence with approved words and whatever grammatical structure conveys that exact meaning naturally — this may mean changing the verb, adding a phrase such as 'make sure that,' or splitting the sentence.
Constraints on the fix
- Never choose a substitute word solely because it is approved if it does not preserve the original meaning.
- Verify the reconstructed sentence is grammatically correct standard English, not just an approved-word patchwork of the original.

Where this fits in AI governance
A rule a checker can test is a rule a model can be held to. The same discipline, on the governance side of this site.
- Prompt engineering
Writing practices are the closest thing the standard has to prompt guidance, and they were written for humans first. - LLM governance, operationally
The prompt is a governed artefact. This is what governing it looks like day to day. - Output validation guardrails
A controlled language is a checkable output constraint. This is the control that treats model output as something to be checked rather than trusted.
