English grammar worksheet focusing on the correct use of indefinite articles 'a' and 'an' in various contexts.

Let's solve the exercises step by step, explaining the rules for using indefinite articles (*a* and *an*) and some in English.

---

✔ Rule Summary:

- Use "a" before consonant sounds.
- Use "an" before vowel sounds (a, e, i, o, u).
- Use "some" for plural nouns or uncountable nouns when referring to an unspecified amount.
- "A" and "an" are used with singular countable nouns.

Note: The sound at the beginning of the word matters, not just the letter.

Examples:
- a university → starts with a /juː/ sound (vowel sound), so "a" is used.
- an hour → starts with a silent 'h', so it’s pronounced /ˈaʊər/, which begins with a vowel sound → "an".

## ✔ Exercise 1: Fill in the correct indefinite article 'a' or 'an'.

> There is a cat on top of your car.
✔ Correct — “cat” starts with a consonant sound (/k/).

Now let’s go through each sentence:

1. Would you like ______ cup of tea?
→ "cup" starts with /k/ (consonant) → a
✔ a

2. I'll have ______ orange, ______ pear and ______ apple, please.
- "orange" starts with /ɒ/ (vowel sound) → an
- "pear" starts with /p/ (consonant) → a
- "apple" starts with /æ/ (vowel sound) → an
✔ an, a, an

3. This is ______ great car.
→ "great" starts with /ɡ/ (consonant) → a
✔ a

4. This is ______ awful car.
→ "awful" starts with /ˈɔːf/ (vowel sound) → an
✔ an

5. We're going to buy ______ yacht.
→ "yacht" starts with /j/ (pronounced like "y") → consonant sound → a
✔ a

6. We're going to buy ______ other yacht.
→ "other" starts with /ʌ/ (vowel sound) → another → but we only need one article → another = an + other, so an
✔ an

7. Is there ______ university in London?
→ "university" starts with /juː/ (vowel sound) → a
✔ a

8. You'll have to go to the hospital for ______ X-ray.

9. She's ______ MP.
→ "MP" is pronounced /em piː/ → starts with /em/ → consonant sound → a
✔ a

10. She's ______ hard-working MP.
→ "hard-working" starts with /h/ → /hɑːrd/ → consonant sound → a
✔ a

11. She's ______ hones MP.
Wait — likely typo. Probably meant "Hones" as in "Honeys" or perhaps "Hones" isn't a real word. But assuming it's "Hones" meaning "Honours MP"? Or maybe it's a name?

But looking at context: probably meant "Hones" → if it's a proper noun, like "Hones", then it starts with /h/ → consonant → a

But more likely: it's a typo for "Honest"? Or "Hones" as in "Hone's"?

Wait — actually, this might be "Hones" as in "Hones MP" = "Hones" is a person’s name.

So: "She's Hones MP" → "Hones" starts with /h/ → consonant → a

But if it's "Hones" as in "Hones" (like "Hones" = "honourable"?), still starts with /h/.

So: a Hones MP → a

✔ a
