Simple explanation
What are articles in English? Articles are small words that come before nouns. They help us understand whether we are talking about something general, something new, or something specific. The main English articles at A1 level are a, an and the. Using a and an A and an usually mean one. We use them before singular countable nouns when we talk about something for the first time or when the listener does not know exactly which thing we mean. The difference between a and an The choice between a and an depends on the first sound of the next word. Use a before a consonant sound and an before a vowel sound. Using the We use the when the listener knows what we are talking about, when something was mentioned before, or when there is only one of something.
