What is a compound sentence?

A compound sentence has two independent clauses (each can stand alone as a complete sentence) joined by a coordinating conjunction:
and, but, or, so, yet, for

We use a comma before the conjunction when joining two independent clauses.

Now let’s go through each one:

---

1) Harry met me this morning. He didn’t mention the camp. (yet)

- Both clauses are independent.
- We're told to use "yet", which shows contrast or surprise.
- "Yet" often implies something unexpected or contrary to expectation.

✔ Combined sentence:
Harry met me this morning, but he didn’t mention the camp.

Wait — the instruction says to use "yet", not "but". But "yet" is usually used at the beginning or end of a sentence, and it's more common with "but" in mid-sentence contrast.

However, "yet" can be used as a coordinating conjunction meaning "but", though it's less common than "but".

So, we can write:
Harry met me this morning, yet he didn’t mention the camp.

✔️ This is correct and grammatically acceptable.

> ✔ Answer: *Harry met me this morning, yet he didn’t mention the camp.*

2) Mia has a golden furry kitten. She calls it Goldie. (and)

- Two independent clauses.
- Use "and" to join them.

✔ Mia has a golden furry kitten, and she calls it Goldie.

> ✔ Answer: *Mia has a golden furry kitten, and she calls it Goldie.*

3) We are dressed in blue and red. We are playing in the band. (for)

- "For" is a coordinating conjunction that shows reason or cause.
- The second clause explains why they are dressed in those colors.

So:
"We are dressed in blue and red for we are playing in the band."

But wait — "for" is rarely used this way in modern English. It's more formal and old-fashioned. However, it's still correct.

Alternatively, you could say:
"We are dressed in blue and red because we are playing in the band."

But since the exercise asks for "for", we must use it.

✔ We are dressed in blue and red, for we are playing in the band.

> ✔ Answer: *We are dressed in blue and red, for we are playing in the band.*

---

4) I will go swimming. I will help Mom make dinner. (or)

- "Or" indicates choice between two options.

So:
"I will go swimming or I will help Mom make dinner."

This means the speaker might do one or the other.

✔ I will go swimming, or I will help Mom make dinner.

> ✔ Answer: *I will go swimming, or I will help Mom make dinner.*

---

5) Lenny has invited me to the parade. I won't be able to make it. (but)

- Contradiction: invited, but can't attend.
- Use "but" to show contrast.

✔ Lenny has invited me to the parade, but I won't be able to make it.

> ✔ Answer: *Lenny has invited me to the parade, but I won't be able to make it.*

---

6) Aunt Grace hasn't been keeping well. Let's visit her today. (so)

- "So" shows result or consequence.
- Because she isn't well → we should visit her.

✔ Aunt Grace hasn't been keeping well, so let's visit her today.

> ✔ Answer: *Aunt Grace hasn't been keeping well, so let's visit her today.*

---

✔ Final Answers:

1) Harry met me this morning, yet he didn’t mention the camp.
2) Mia has a golden furry kitten, and she calls it Goldie.
3) We are dressed in blue and red, for we are playing in the band.
4) I will go swimming, or I will help Mom make dinner.
5) Lenny has invited me to the parade, but I won't be able to make it.
6) Aunt Grace hasn't been keeping well, so let's visit her today.

🔍 Explanation Summary:

- Always check if both clauses are independent.
- Use a comma before the coordinating conjunction.
- Choose the right conjunction based on meaning:
- and = addition
- but = contrast
- or = choice
- so = result
- yet = contrast (more formal)
- for = reason (formal)

These sentences now correctly form compound sentences using the given conjunctions.
