Expert writing Tips

Best practice

When using "which needs to", ensure the relative clause is clearly linked to the noun it modifies to avoid ambiguity. For example, "The report, which needs to be completed by Friday, is essential for the meeting."

Common error

Avoid placing the "which needs to" clause in a way that it modifies the wrong noun. For instance, instead of "The car, which needs to be repaired, was parked in the garage", be precise: "The car that needs to be repaired was parked in the garage."
