Expert writing Tips

Best practice

When using "guaranteed by", clearly state the entity providing the guarantee to avoid ambiguity. For example, "The loan is guaranteed by the government" is more precise than "The loan is guaranteed."

Common error

Avoid using "guaranteed by" when the entity offering the guarantee is unclear or lacks the authority to do so. Claims like "This diet is guaranteed by experts" are misleading without specifying which experts and their credentials.
