Expert writing Tips
Best practice
When describing duration, ensure the verb tense and article usage are grammatically correct. Usually, "persisted until" (without the article "a") is preferred.
Common error
Avoid adding an indefinite article ("a") before "persisted until" unless you're referring to a specific instance or item that persisted. For example, it is correct to say "a problem persisted until..." but incorrect to say "a feeling persisted until..."

When describing duration, using "persisted until" or alternatives like "lasted until" and "continued until" is recommended to ensure clarity and grammatical correctness. While authoritative sources like The New York Times and Britannica are present in the results, the grammatical structure is the primary concern.
