Expert writing Tips
Best practice
For clarity, use "one-day deadline" or "deadline in one day" instead of "deadline one day". These alternatives are grammatically correct and easier to understand.
Common error
Avoid placing "one day" directly after "deadline" without a hyphen, as it sounds awkward. Remember that descriptive adjectives should precede the noun they modify. Use "one-day deadline" to clarify the duration.
