Expert writing Tips

Best practice

When using "once", ensure it's part of a grammatically complete clause such as "once it has" to avoid ambiguity and ensure clarity in your writing.

Common error

Avoid using "once has" as a standalone phrase. Always ensure it's followed by a subject or complete clause to make the sentence grammatically correct. For example, use "once it has been determined" instead of just "once has" by itself.

Ludwig's WRAP-UP

In summary, while the phrase "once has" appears frequently, especially in News & Media and Scientific contexts, it's often flagged by Ludwig AI as grammatically incorrect or incomplete.
