Expert writing Tips
Best practice
In formal writing, consider stronger verbs like 'founded', 'instituted', or 'initiated' instead of 'established' to add precision and impact.
Common error
A common mistake is using "that" instead of "which" for nonrestrictive clauses. Use "which" when the information is extra and can be removed without changing the core meaning of the sentence. For example: 'The company, which was established in 1995, is now a market leader'.
