Use Of The A And An Questions Medium
Yes, you can use "a" or "an" before words starting with a consonant cluster. The choice between "a" and "an" depends on the sound that follows the article, not the consonant cluster itself.
If the sound that follows the article is a vowel sound, you should use "an." For example, "an hour" (pronounced as "an ow-er") or "an honest person" (pronounced as "an on-est person").
If the sound that follows the article is a consonant sound, you should use "a." For example, "a strong wind" (pronounced as "a str-ong wind") or "a great book" (pronounced as "a gr-ate book").
So, it is not the consonant cluster that determines the use of "a" or "an," but rather the sound that follows the article.
