Expert writing Tips

Best practice

When referring to two individuals or entities that share a characteristic, prefer using "both of whom" or "both individuals who" for clearer and grammatically correct sentences. For example, instead of "The founders, both who have experience…", write "The founders, both of whom have experience…".

Common error

Avoid using "both who" directly as it often leads to grammatically incorrect sentences. This construction typically arises when trying to combine "both" with a relative clause. Use "both of whom" or rephrase the sentence to ensure clarity and grammatical accuracy. For example, instead of "They selected two candidates, both who were highly qualified," revise it to "They selected two candidates, both of whom were highly qualified."
