Expert writing Tips

Best practice

For clarity, specify the context when using "a third of the time". For instance, instead of just saying "It rains a third of the time", specify "It rains a third of the time during the monsoon season".

Common error

Don't assume "a third of the time" implies predictability. Just because something occurs a third of the time doesn't mean it will happen predictably every third instance. Probability doesn't guarantee regularity.
