Expert writing Tips

Best practice

When aiming for conciseness, consider if "could have" alone sufficiently conveys your intended meaning, as "possibly" can sometimes be redundant.

Common error

Avoid stacking adverbs of possibility. While "could have possibly" is acceptable, adding further adverbs like "maybe" or "perhaps" weakens the sentence and sounds redundant. Choose one adverb to maintain clarity.
