This beginner grammar worksheet helps students practice using the articles a and an correctly before vowel and consonant sounds.

Let's solve the grammar exercise step by step. The task is to choose between "a" or "an" before each noun in the sentences.

🔹 Rule Reminder:

- Use "a" before words that start with a consonant sound.
- Use "an" before words that start with a vowel sound (a, e, i, o, u).

Note: It’s about the sound, not just the letter. For example, "university" starts with a 'u' but sounds like "yoo", so we say "a university" because it starts with a consonant *sound*.
