Expert writing Tips
Best practice
When using "delivery prolonged", ensure the context clearly indicates what is being delivered and the reason for the prolongation. This helps avoid ambiguity and ensures clarity in your communication.
Common error
Avoid using "delivery prolonged" when you actually mean sustained release. "Delivery prolonged" describes a delay or extension in the delivery process itself. Sustained release, especially in drug delivery, refers to a controlled release of a substance over a period of time, which is a planned feature, not necessarily a delay.
