Expert writing Tips

Best practice

When using "be sure not to", consider the tone you want to convey. It can range from a gentle reminder to a firm instruction. Choose alternatives if the tone doesn't quite fit your needs.

Common error

While "be sure not to" is useful, excessive use of negative constraints can make your writing sound overly critical or negative. Try phrasing some instructions positively instead. For example, instead of "Be sure not to overcook the cookies", try "Bake the cookies until they are golden brown".
