Worksheet for diagramming subjects and predicates with example and exercises.

Let's solve this sentence diagramming worksheet step by step. The goal is to diagram each sentence, showing the subject(s) and predicate(s) using the correct format.

---

🔹 Rules for Diagramming Subjects and Predicates:

- The subject goes on the left of a horizontal line.
- The predicate goes on the right.
- For compound subjects or predicates, use a vertical line (|) to separate them, and connect with a small diagonal line if needed.
- Use "and" or "but" as connecting words in compound sentences; they go on a small diagonal line between the two parts.

---

We'll go through each sentence:

---

1. Grass grows.

- Subject: *Grass*
- Predicate: *grows*

✔ Diagram:
```
Grass | grows
```

---

2. Dogs play.

- Subject: *Dogs*
- Predicate: *play*

✔ Diagram:
```
Dogs | play
```

---

3. Cats and kittens purr.

- Compound subject: *Cats* and *kittens*
- Predicate: *purr*

✔ Diagram:
```
Cats | kittens | purr
\___________/
and
```

> The "and" connects the two subjects. Draw a vertical line between them, then a diagonal line from the middle down to "and".

---

4. John and I raced.

- Compound subject: *John* and *I*
- Predicate: *raced*

✔ Diagram:
```
John | I | raced
\_________/
and
```

> Same structure as #3 — compound subject.

---

5. Jeff laughed and chuckled. *(Example given)*

This one is already done correctly:
```
Jeff | laughed
| and
| chuckled
```

> Compound predicate: *laughed* and *chuckled*. "And" connects the verbs.

---

6. Caroline wrote and drew.

- Subject: *Caroline*
- Compound predicate: *wrote* and *drew*

✔ Diagram:
```
Caroline | wrote
| and
| drew
```

> Similar to #5 — compound predicate.

---

7. Jeff and Marie sing and dance.

- Compound subject: *Jeff* and *Marie*
- Compound predicate: *sing* and *dance*

✔ Diagram:
```
Jeff | Marie | sing
\__________/ | and
| dance
```

> You need two vertical lines:
- One to separate the subjects (Jeff and Marie)
- One to separate the verbs (sing and dance)

But since both are compound, you can do it like this:

```
Jeff | Marie | sing
\__________/ | and
| dance
```

Or more clearly:

```
Jeff | Marie | sing
\__________/ | and
| dance
```

> This shows that both subjects perform both actions.

---

8. Connor and Kelsey tried but lost.

- Compound subject: *Connor* and *Kelsey*
- Compound predicate: *tried* and *lost*, joined by "but"

✔ Diagram:
```
Connor | Kelsey | tried
\__________/ | but
| lost
```

> "But" is a conjunction showing contrast between the two actions.

---

✔ Final Answer Summary:

Here’s how each should be diagrammed:

---

1. Grass grows.
```
Grass | grows
```

2. Dogs play.
```
Dogs | play
```

3. Cats and kittens purr.
```
Cats | kittens | purr
\___________/
and
```

4. John and I raced.
```
John | I | raced
\_________/
and
```

5. Jeff laughed and chuckled.
*(Already provided)*
```
Jeff | laughed
| and
| chuckled
```

6. Caroline wrote and drew.
```
Caroline | wrote
| and
| drew
```

7. Jeff and Marie sing and dance.
```
Jeff | Marie | sing
\__________/ | and
| dance
```

8. Connor and Kelsey tried but lost.
```
Connor | Kelsey | tried
\__________/ | but
| lost
```

📝 Tips:

- Always identify who/what (subject) and what they do (predicate).
- Use vertical lines to separate compound parts.
- Place conjunctions (*and, but*) on a small diagonal line between the parts.
- Keep the subject on the left, predicate on the right.
