Expert writing Tips

Best practice

When using "is of class", ensure the context clearly defines the specific classification system or category being referenced. For instance, specify "is of class C1" rather than just "is of class" to avoid ambiguity.

Common error

Avoid using "is of class" when a simpler, more direct phrasing would suffice. Instead of "the function is of class C1", consider "the function is C1" for conciseness.
