Expert writing Tips
Best practice
When describing the duration of use, prioritize clarity. Instead of "two years used", opt for phrases like "in use for two years" or "used for two years" to ensure grammatical correctness and avoid ambiguity.
Common error
Avoid using "used" directly after a time period without a connecting preposition. "Two years used" implies an incomplete thought. Instead, clarify the sentence to show what has been "used" during those two years, e.g., "The equipment was used for two years".
