How to use "a unreliable"

What Does "a unreliable" Mean?

• The phrase "a unreliable" is grammatically incorrect and doesn't have a standard meaning. It's a common error arising from misapplication of the rules for indefinite articles.
• The phrase is not compositional because the combination is ungrammatical.
• Register: N/A, as the phrase is incorrect.

How to Use It

• Grammatical pattern: Article + Adjective + Noun (where the adjective modifies the noun). The error arises in the article choice.
• The correct form is "an unreliable" followed by a noun (e.g., "an unreliable car," "an unreliable source").
• The components should not be separated (e.g., "a very unreliable" is acceptable, but the article must agree with the sound of the first word of the adjective phrase).
• What sounds unnatural: Using "a" before any word starting with a vowel sound is incorrect. Using "a unreliable" is the specific error addressed here.

FAQs

Can the parts of "a unreliable" be separated, or must they stay together?

The phrase itself is incorrect. You can insert adverbs between the article and the adjective (e.g., "an incredibly unreliable source"), but the article must still agree with the sound of the first word following it. So, the correct form would always be with "an" before "unreliable".
