Expert writing Tips

Best practice

When aiming for clarity and grammatical accuracy, replace "corroborated with him" with "corroborated by him" or rephrase the sentence to use a more standard construction like "his account was corroborated".

Common error

Avoid using "with" to indicate the agent performing the corroboration. "With" typically denotes accompaniment or means, not the source of confirmation. Use "by" to clearly show who or what is providing the corroboration.
