Expert writing Tips
Best practice
If you wish to use the article "a", you must insert a modifier starting with a consonant sound, for example: "a previously unreported" discovery.
Common error
Be careful not to mistake list markers like "(a) unreported" for a grammatical error. In scientific papers, you might see "(a) unreported data vs (b) reported data", where "a" is simply a bullet point or label. However, in standard prose, "a unreported" is always a mistake.
Linguistic Context
The phrase "a unreported" attempts to function as an adjective phrase modified by an indefinite article, but it fails to follow the morphological rules of English. According to Ludwig, the indefinite article "a" must change to "an" when the following word begins with a vowel sound to facilitate easier pronunciation (elision).

Ludwig's WRAP-UP
In conclusion, "a unreported" is a grammatical error that should be avoided in all forms of writing. Ludwig AI consistently indicates that the correct form is "an unreported", as the word starts with a vowel sound. While the search results show instances of these words appearing together in scientific lists (e.g., as part of a list (a), (b), (c)), these are not grammatical phrases. For writers looking to maintain a professional or academic tone, using the correct article is essential. If you prefer the sound of "a", you must include an intervening adverb such as in the phrase "a previously unreported" finding, which appears frequently in high-quality sources like Nature and The Guardian.

FAQs
Is "a unreported" grammatically correct?
No, it is not correct. Because the word "unreported" begins with a vowel sound, you must use the indefinite article "an". You should say "an unreported" instead.
What can I say instead of "a unreported"?
Depending on your meaning, you can use "an unreported" for the correct grammar, or synonyms like "an undisclosed" or "an unrecorded".
Why does Ludwig AI flag "a unreported" as an error?
Ludwig AI identifies this as an error based on standard English syntax rules regarding indefinite articles. The tool suggests replacing it with "an unreported" to maintain professional writing standards.
When is it acceptable to see "a" followed by "unreported"?
This only occurs when "a" is a list identifier (e.g., "item a: unreported stats") or when a word starting with a consonant is placed between them, such as "a largely unreported" story.
