Is it correct to say or write an student or an store?

    How do you pronounce st? This doesn't feel natural.

    I've noticed that speakers of Tagalog, for instance, seem to have difficulty saying words beginning with an S consonant blend, preferring to say estore or estudent.

    moioci: I believe people around the world also do that. Since there is no word starting with s followed by consonant in Portuguese, people tend to think and speak like /ɪstɔːr/ instead of /stɔːr/ Nov 17, 2010 at 23:56

    Ditto with Hindi/Urdu speakers (i.e., they also tend to pronounce them istudent and iscore), but anyone with sufficient practice can cure themselves of this habit. Feb 8, 2011 at 9:06

Always use an for words which sound like they start with a vowel, and always use a for words which sound like they start with a consonant. The rules for h are more complex, and it can be ok to use either.

The usage of the indefinite article preceding h are discussed here. In particular, look at nohat's response.

As for student and store, they should always be preceded with a and never with an, because they both start with the consonant /s/ when spoken.


A student, a store


An student, an store

    So e.g. A united states citizen, a unique opportunity but an uncle?

    Many Spaniards speaking English say "an (e)student"

The quickest way to remember the rule for this: "an hour and a half". Thus, "a" for something with an initial consonant sound, and "an" otherwise.
