Expert writing Tips
Best practice
When using "sometime before", ensure the context makes the temporal relationship clear. Avoid ambiguity by providing a specific reference point. For example, instead of "The package will arrive sometime before", specify "The package will arrive sometime before Friday".
Common error
Avoid using "sometime before" without any contextual clues, as it can lead to confusion. Instead of saying "I'll call you sometime before", provide a more precise timeframe, such as "I'll call you sometime before noon".
