Expert writing Tips
Best practice
Use "not definitively" when you want to express uncertainty or indicate that a conclusion is not fully supported by evidence. It's suitable for academic writing, journalism, and general communication where precision is valued.
Common error
Avoid using "not definitively" when the evidence strongly suggests a conclusion, even if absolute certainty is unattainable. Overusing it can weaken your argument. Instead, consider using qualifiers like "probably" or "likely" if the evidence points in a certain direction.
