  • Impossible to tell for sure without the context. What document? – deadrat Nov 7 '15 at 4:43
  • Yes, the use of the article "an" is correct. – Hot Licks Nov 7 '15 at 5:31

Yes it is.

If there is an adjective or an adverb-adjective combination before the noun, A(AN) should agree with the first sound in the adjective or the adverb-adjective combination.


  • He is an excellent teacher.

  • I saw a really beautiful eagle at the zoo.


  • $30,000 treated as singular? – AnArticle Nov 7 '15 at 4:55
  • Oh, I didn't get the specific issue. This question may be helpful. – user139454 Nov 7 '15 at 5:04
  • Yes, the amount is linguistically singular, because there's only one "additional" amount. (Would still be singular for "amazing" or "fantastic", etc.) – Hot Licks Nov 7 '15 at 5:34
