Expert writing Tips
Best practice
When describing a resource or asset that could be put to better use, consider using "an unused" to highlight the potential benefit of activating it. For example, "an unused conference room" could be repurposed as a collaborative workspace.
Common error
Avoid using "an unused" when you mean 'not needed'. While similar, "an unused" item implies potential use, while 'not needed' suggests it's superfluous. For example, instead of 'an unused function of the software' say 'an unneeded function of the software'.
