Expert writing Tips

Best practice

When instructing someone, use "must use" to clearly communicate a non-negotiable requirement. For example: "To access the secure network, you "must use" a VPN."

Common error

Avoid using "must use" when implying a suggestion rather than a strict requirement. Overusing it can make instructions seem overly demanding. Instead, consider alternatives like "should use" or "it is recommended to use" for softer suggestions.
