Sentence & word composition
What is it? Who is it? Simple sentences with a/an
The indefinite article “a/an” means one thing or one person. It can't be used with the plural. We normally use it to speak about categories and characteristics. We put “an” before the vowels, but not before a silent "h" or when "u" sounds like [yu]. The exercises on this page are designed for beginners. They will enable you to practise when to use “a” or “an” and how to use the indefinite article in simple sentences.
