Expert writing Tips

Best practice

Consider the specific decade or era you're referencing. If precision is important, specify "in the 1980s" instead of simply saying "decades ago".

Common error

Avoid using "decades ago" when the exact number of years is crucial. If you mean 20 years, specifying "two decades ago" is more accurate than a generalized timeframe.
