Comma Worksheet for Coordinate Adjectives – Practice rewriting sentences with proper comma usage.

Let’s go through each sentence one by one. The rule is: if two adjectives describe the same noun and you can put “and” between them (or swap their order), then they are coordinate adjectives — and you need a comma between them.

We’ll check each sentence, decide if the adjectives are coordinate, and add a comma if needed.

1. The weather man warned of hot windy conditions.

- Adjectives: “hot” and “windy”
- Can we say “hot and windy”? Yes.
- Can we say “windy and hot”? Also yes.
→ So they are coordinate → Add comma.

✔ Rewritten: The weather man warned of hot, windy conditions.

2. The man gave a tough long-winded speech.

- Adjectives: “tough” and “long-winded”
- “Tough and long-winded”? Sounds okay.
- “Long-winded and tough”? Also works.
→ Coordinate → Add comma.

✔ Rewritten: The man gave a tough, long-winded speech.

*(Note: “long-winded” is hyphenated because it’s a compound adjective — but that doesn’t affect the comma rule here.)*

3. My mom showed me a new fun-filled way of cooking.

- Adjectives: “new” and “fun-filled”
- “New and fun-filled”? Okay.
- “Fun-filled and new”? Also fine.
→ Coordinate → Add comma.

✔ Rewritten: My mom showed me a new, fun-filled way of cooking.

4. I visited Florida and it had hot humid weather.

- Adjectives: “hot” and “humid”
- “Hot and humid”? Very common phrase.
- “Humid and hot”? Also natural.
→ Coordinate → Add comma.

✔ Rewritten: I visited Florida and it had hot, humid weather.

5. I had a scary frightening experience at the movie theatre.

- Adjectives: “scary” and “frightening”
- These mean almost the same thing!
- “Scary and frightening”? Redundant but grammatically okay.
- “Frightening and scary”? Also fine.
→ Coordinate → Add comma.

✔ Rewritten: I had a scary, frightening experience at the movie theatre.

6. The actor had breathtakingly cruel and callous actions.

Wait — look closely: “breathtakingly” is an adverb modifying “cruel”, not an adjective describing “actions”. Then we have “cruel and callous” — which are joined by “and”, so no comma needed between them.

But the instruction says to separate *coordinate adjectives*. Here, “breathtakingly” isn’t an adjective — it’s an adverb. So only “cruel” and “callous” are adjectives — and they’re already connected with “and”, so no comma needed.

Actually — let’s double-check: Is “breathtakingly cruel” acting as one unit? Yes. And “callous” is another adjective. But since “cruel and callous” are linked by “and”, we don’t use a comma there.

So this sentence does NOT need any commas added for coordinate adjectives.

✔ Rewritten: The actor had breathtakingly cruel and callous actions. *(No change needed)*

7. The man gave a high pitched enjoyable announcement at the wedding.

First — “high pitched” should be hyphenated: “high-pitched” (compound adjective).

Adjectives: “high-pitched” and “enjoyable”

- “High-pitched and enjoyable”? Makes sense.
- “Enjoyable and high-pitched”? Also fine.
→ Coordinate → Add comma.

✔ Rewritten: The man gave a high-pitched, enjoyable announcement at the wedding.

---

8. My dad warned me of a difficult hard-nosed basketball game.

“Hard-nosed” is a compound adjective (hyphenated).

Adjectives: “difficult” and “hard-nosed”

- “Difficult and hard-nosed”? Okay.
- “Hard-nosed and difficult”? Also fine.
→ Coordinate → Add comma.

✔ Rewritten: My dad warned me of a difficult, hard-nosed basketball game.
