Expert writing Tips

Best practice

When describing events in time, use clearer and more precise phrases like "before or after" or "earlier or later" to avoid ambiguity.

Common error

Avoid using the phrase "ago or later" as it does not logically connect a past event with a future possibility. Instead, specify the intended temporal relationship with phrases like "before and after" or "at any point in the past or future".
