Expert writing Tips
Best practice
Always use the correct grammatical form: "has not yet been". For example, instead of writing "The research is not yet been published", write "The research "has not yet been" published."
Common error
The incorrect use of "is" instead of "has" creates a grammatically flawed structure. "Is" typically indicates a present state, while "has" is used to form the present perfect tense, which is needed to express that something hasn't happened up to the present.

FAQs
What is the correct way to say something hasn't happened yet?
The correct way to express that something hasn't happened yet is to use ""has not yet been"" or "has yet to be". For example, "The results "has not yet been" announced".
What are some alternatives to "is not yet been"?
Alternatives include "is still not", "remains un", or restructuring the sentence to use the correct tense. For example, instead of "The issue is not yet been resolved", use "The issue is still not resolved".
Why is "is not yet been" considered grammatically incorrect?
The phrase combines the present tense auxiliary verb "is" with the past participle "been" incorrectly. The present perfect tense, requiring "has" or "have", is needed to accurately convey that an action has not yet occurred.
How can I avoid using "is not yet been" in my writing?
Always double-check the tense of your sentence. If you're trying to say something hasn't happened, use "has not been" or "has yet to be". For instance, "The problem "has not been" solved" is correct.
