Expert writing Tips

Best practice

When describing the duration of a state or condition, use grammatically correct alternatives like "which lasted for" or "which was maintained for" to ensure clarity and accuracy.

Common error

Avoid using incomplete relative clauses like "which maintained for". Always ensure the clause has a complete verb phrase to accurately convey the intended meaning. Add the auxiliary verb to create a grammatically correct structure, such as "which was maintained for".
