Expert writing Tips

Best practice

Although commonly used, consider using the grammatically correct alternative "on several occasions" for improved clarity and professionalism in formal writing.

Common error

Many writers incorrectly use "instances" when they mean "occasions". Remember that "occasion" refers to a specific time something happens, while "instance" refers to a particular example or case. Choose "on several occasions" for referring to multiple times.
