FAQs

Why is "a sector" correct, but "an sector" incorrect?

The choice between "a" and "an" depends on the sound of the word that follows. "Sector" begins with a consonant sound, so the correct article is "a", as in "a sector".

What are some alternatives to the phrase "an sector"?

Since "an sector" is grammatically incorrect, use "a sector". Other alternatives include "a segment" or "a division".

How do I know whether to use "a" or "an" before a noun?

Use "a" before words that begin with a consonant sound, and "an" before words that start with a vowel sound. For example, "a sector" is correct because "sector" begins with the consonant 's', while "an apple" is correct because "apple" starts with the vowel 'a'.

Is it ever correct to use "an" before a word starting with 's'?

Yes, but only when the 's' is silent, which is rare in modern English. For example, in some dialects, "an heir" is used, where the 'h' is silent. However, with "sector", the 's' is always pronounced, so it's always "a sector".
