Best practice

When describing the duration of a process or experiment, specify the units of time (e.g., days, months, years) to provide clarity and context. For example, instead of saying "The study was conducted "over a long duration", say "The study was conducted "over a long duration" of three years.".

Common error

Don't use "over a long duration" without providing some context or specific timeframe. Saying something lasted "over a long duration" is vague and doesn't give the reader a clear sense of the actual timescale involved. Instead, be specific by saying "over several months" or "over many years".
