# 19A Making the Important Point Clear

Precise communication sometimes requires more than stating a fact; I may need to correct an assumption or show which condition made a result possible.
For example, a successful build does not by itself establish that an updated page is visible in the production environment used by ordinary visitors.
I can express this limitation with an ordinary sentence and then choose a stronger structure when the distinction deserves particular attention.
Only after we checked the production page did we confirm that the update was actually available to the intended audience.
The opening phrase limits the condition for confirmation, and the following auxiliary moves before the subject to create partial inversion.
This structure sounds more formal than a normal progress report, so it is useful when the emphasis has a clear communicative purpose.
I can also highlight the cause with a cleft sentence, saying that it was the configuration value that caused the failed request.
The emphasis identifies the relevant cause without requiring me to claim that every other part of the system has been examined or proved correct.
When I correct an earlier interpretation, I state the intended meaning clearly and explain which part of the previous statement was too broad.
The purpose of emphasis is to make a meaningful distinction easier to understand, not to make an ordinary message sound unnecessarily complicated or impressive.
