Expert writing Tips
Best practice
Use "a" as the indefinite article because the sound following it is a consonant sound (n).
Common error
Do not use the indefinite article "an" with "non-responsive". While you would use "an unresponsive" because it begins with a vowel sound, "non-responsive" starts with a consonant sound and requires "a".

Ludwig's WRAP-UP
The phrase "a non-responsive" is a versatile and grammatically correct adjective phrase used to describe entities that fail to provide a reaction. According to Ludwig AI, it is particularly prominent in the fields of medicine, biology, and technology, where precise classification of behavior is required. Unlike its synonym "an unresponsive", the hyphenated form "non-responsive" is favored in formal scientific reporting for its objective tone. Writers should be careful to use the article "a" rather than "an" and ensure the hyphen is present when modifying a noun. Overall, it is a robust, professional choice for technical and journalistic writing.
