Expert writing Tips
Best practice
Use "where required" to clearly indicate optional steps or elements in a process or instruction, enhancing clarity and avoiding unnecessary actions. For example: 'Complete section three of the form, where required, based on your specific circumstances.'
Common error
Avoid using "where required" when the necessity is already implied or obvious from the context. Redundancy can clutter your writing and reduce its impact. For example, instead of saying 'Add water, where required, to maintain consistency', simply state 'Add water to maintain consistency' if the need for water is self-evident.
