Expert writing Tips

Best practice

When offering choices, use "either or both" to clearly indicate that selecting one, the other, or a combination of both is acceptable. This avoids ambiguity and ensures your audience understands all available options.

Common error

Don't use "either or both" when the context already implies that both options are permissible. Overuse can make your writing sound repetitive and less concise. For instance, instead of saying "You can use either or both methods if they are effective", simply state "You can use the methods if they are effective" when it's obvious that using both together is an option.
