Expert writing Tips

Best practice

Always use "a number of" instead of "an number of". The article 'a' is correct before the noun 'number'.

Common error

Avoid using "an" before words starting with a consonant sound. Remember that 'number' begins with a consonant sound, so the correct article is 'a'.
