Worksheet on compound subjects with examples and practice exercises.

Let’s go through each sentence and combine the subjects using “and” to make a compound subject. Remember: when you have two or more subjects doing the same thing, you can join them with “and” — that’s called a compound subject.

We’ll take each pair of sentences and turn them into one sentence with a compound subject.

1. Rain and snow are forms of precipitation.
→ Already has a compound subject! No change needed.
✔ Final: Rain and snow are forms of precipitation.

2. Wet weather can also include sleet or hail.
→ This is talking about wet weather including other things — not two subjects doing the same action. But we’re supposed to describe the *subject* in each sentence as a compound subject. Wait — actually, looking again, this sentence doesn’t have two separate subjects being combined. Let’s read the instruction: “Write compound or not compound to describe the subject in each sentence.” Oh! Maybe we just need to say whether the subject is already compound or not? But then part B says “Combine the subjects...” so maybe for part A, we’re just identifying if the subject is compound or not?

Wait — let me re-read the worksheet.

Actually, looking at the top box: it says “A compound subject has two or more nouns or pronouns with the same predicate.” Then there’s an example: “Bicyclists and bicyclists cause damage.” So they want us to identify if the subject is compound (two+ nouns) or not.

But then part A says: “Write compound or not compound to describe the subject in each sentence.”

So for each sentence in part A, we look at the subject and decide: is it made of two or more nouns/pronouns joined by “and”? If yes → compound. If no → not compound.

Let’s do that:

---

1. Rain and snow are forms of precipitation.
Subject: “Rain and snow” → two nouns joined by “and” → ✔ compound

2. Wet weather can also include sleet or hail.
Subject: “Wet weather” → one noun phrase → ✘ not compound

3. A blustery wind is noisy and stormy.
Subject: “A blustery wind” → one noun → ✘ not compound

4. Cirrus clouds and cumulus clouds usually mean fair weather.
Subject: “Cirrus clouds and cumulus clouds” → two nouns joined by “and” → ✔ compound

5. Squalls and gales are two kinds of wind storms.
Subject: “Squalls and gales” → two nouns → ✔ compound

6. Another name for a cyclone is a typhoon.
Subject: “Another name for a cyclone” → one noun phrase → ✘ not compound

7. Sudden days can bring heat and humidity.
Subject: “Sudden days” → one noun → ✘ not compound

Now part B: Combine the subjects in these sentences to make one new sentence with a compound subject.

That means: take the two separate subjects from the two sentences and join them with “and”, then use the verb that fits both.

Let’s do each one:

8. Fog covered the land. Mist covered the land.
Both have same verb: “covered the land”
Subjects: “Fog” and “Mist”
→ Combine: Fog and mist covered the land.

9. Santa Ana winds are hot. Sirocco winds are hot.
Same predicate: “are hot”
Subjects: “Santa Ana winds” and “Sirocco winds”
→ Combine: Santa Ana winds and Sirocco winds are hot.

10. Umbrellas keep people dry. Raincoats keep people dry.
Same predicate: “keep people dry”
Subjects: “Umbrellas” and “Raincoats”
→ Combine: Umbrellas and raincoats keep people dry.
