Expert writing Tips
Best practice
When using "are not identified", ensure the context clearly indicates what is doing the identifying and what criteria are used for identification. This adds precision and avoids ambiguity.
Common error
While "are not identified" is grammatically correct, overuse of the passive voice can make writing seem vague or less direct. Consider if using an active voice construction would be more effective and engaging. For example, instead of "the errors are not identified", try "the system fails to identify the errors".

Ludwig's WRAP-UP
The phrase "are not identified" is a grammatically sound and frequently used passive construction, as confirmed by Ludwig. It serves to indicate a lack of recognition or specification, commonly found in scientific and news contexts. While versatile, it's important to consider the potential overuse of the passive voice and ensure clear context. Alternatives like "remain unrecognised" or "cannot be identified" may offer more nuanced expressions. Usage should be carefully considered to maintain clarity and avoid vagueness.
