Expert writing Tips
Best practice
When using "a certain increase", ensure the context provides some indication of the nature or scope of the increase, even if the exact amount is unspecified. This helps avoid vagueness and provides clarity to the reader.
Common error
Avoid using "a certain increase" as a generic filler. If possible, quantify the increase or specify its nature to provide more meaningful information. For example, instead of saying "there was a certain increase in sales", specify "there was a 15% increase in sales" or "there was a noticeable increase in online sales".
