Expert writing Tips
Best practice
Always use the grammatically correct form "it was designed by" or "it is designed by" when attributing the design of something. For example, instead of saying "the app it designed by a student", say "the app was designed by a student."
Common error
Ensure the phrase includes the auxiliary verb "was" or "is" to form a grammatically correct passive sentence. Omitting the auxiliary verb results in an ungrammatical construction.

Ludwig's WRAP-UP
In summary, the phrase "it designed by" is grammatically incorrect and should be avoided. As highlighted by Ludwig AI, the proper phrasing is either "it was designed by" or "it is designed by". While examples exist in various sources like The New York Times and The Guardian, their presence doesn't validate the incorrect grammar. The intended purpose of attributing design is clear, but the flawed grammar hinders effective communication, making it unsuitable for professional or academic contexts. Always ensure the inclusion of the auxiliary verb for grammatical correctness. Consider using alternative phrasing like "it is the creation of" or "the design is attributed to" for better clarity and accuracy.
