Expert writing Tips
Best practice
Use "on the deadline" to clearly specify that an action must be completed by the final, designated time. This avoids ambiguity compared to phrases like "near the deadline", which suggests approximation rather than precision.
Common error
Avoid using "on the deadline" when you mean "before the deadline". "On the deadline" specifies the exact final moment for completion, while "before the deadline" allows for completion any time leading up to that moment. Understand the difference to communicate accurately.
