Sentence Types Worksheet for Grammar Practice

Let’s go through each sentence one by one. We’ll figure out what type of sentence it is based on the rules given:

- Simple Sentence: Only one clause (one subject + predicate).
- Compound Sentence: Two or more clauses joined by a coordinating conjunction (for, and, nor, but, or, yet, so).
- Complex Sentence: Two or more clauses joined by a subordinating conjunction (as, because, although, since, before, when, once, if, even if, whatever, whenever, during, until, unless, wherever, whether, while, as if, even if, that).
- Compound-Complex: Three or more clauses — must have at least one coordinating AND one subordinating conjunction.

We’ll also look for subjects and predicates, and separate clauses with a line where needed.

1. When I get home from school, I'm going to take a nap.

→ “When I get home from school” = dependent clause (starts with subordinating conjunction “when”)
→ “I’m going to take a nap” = independent clause
→ One subordinating conjunction → Complex Sentence

Sentence Type: Complex

2. I got in trouble so I can't go to the party, but it would have been fun.

Break it down:
- Clause 1: “I got in trouble” → independent
- Clause 2: “so I can’t go to the party” → “so” is coordinating → connects two independents? Wait — actually, “so” here is acting as a coordinating conjunction joining “I got in trouble” and “I can’t go to the party”. But then there’s “but” connecting another clause: “it would have been fun”.

So we have:
- “I got in trouble” (independent)
- “so I can’t go to the party” → this is still part of the first compound idea? Actually, let’s rephrase: The structure is:

“I got in trouble so I can’t go to the party” — this could be seen as one unit? No — better to split:

Actually, standard analysis:
- “I got in trouble” — independent
- “so I can’t go to the party” — “so” is coordinating → so this is second independent clause
- “but it would have been fun” — “but” is coordinating → third independent clause

Wait — that would make it three independent clauses joined by coordinating conjunctions → that’s Compound, not Compound-Complex, because no subordinating conjunction.

But wait — is “so” always coordinating? Yes, in this context. And “but” is coordinating.

So: Three independent clauses? Let’s check:

Clause A: I got in trouble
Clause B: I can’t go to the party (joined to A by “so”)
Clause C: it would have been fun (joined to B by “but”)

All are independent → so this is a Compound Sentence with three clauses? But definition says “two or more clauses joined by coordinating conjunction” — doesn’t say only two. So yes, still compound.

BUT — some might argue “so I can’t go to the party” is a result clause — but grammatically, “so” is listed as coordinating.

However, looking again: “I got in trouble so I can’t go to the party” — this is often treated as one compound sentence (two clauses), and then “but it would have been fun” adds a third clause.

So total: three independent clauses → still Compound Sentence? Or does having three make it something else?

Wait — the definition says:

> Compound Sentence: a sentence with two or more clauses joined by a coordinating conjunction.

It doesn’t limit to two. So even three is still compound.

BUT — hold on! Is there any subordinating conjunction? No. All conjunctions used are coordinating: “so”, “but”.

So this should be Compound.

Wait — but let me double-check common usage. Sometimes sentences like this are called compound-complex if they have multiple layers — but according to the worksheet’s own definition:

> Compound-Complex: three or more clauses joined by coordinating and subordinating conjunctions.

Here, NO subordinating conjunction → so cannot be compound-complex.

Therefore: Compound Sentence

Sentence Type: Compound

3. Being alone can be scary unless you keep yourself busy.

→ “Being alone can be scary” — independent clause
→ “unless you keep yourself busy” — dependent clause (“unless” is subordinating)
→ One subordinating conjunction → Complex Sentence

Sentence Type: Complex

4. Mr. Morton, the best reading teacher in the world, taught me sentence structure.

This has an appositive phrase: “the best reading teacher in the world” — which describes Mr. Morton. It’s not a separate clause — it’s just extra info within one clause.

Subject: Mr. Morton
Predicate: taught me sentence structure

Only one clause → Simple Sentence

Sentence Type: Simple

5. Keith, Carrie, and Kyle bought donuts and ate them down by the river.

Subject: Keith, Carrie, and Kyle (compound subject)
Predicates: bought donuts / ate them — connected by “and”

But note: This is ONE subject doing TWO actions — still considered ONE clause because there’s only one subject group and the verbs are coordinated.

No subordinate or additional independent clauses → Simple Sentence

Sentence Type: Simple

6. I left early so that I could get some work done, but I'll be back soon.

Breakdown:
- “I left early” — independent
- “so that I could get some work done” — “so that” is a subordinating conjunction → dependent clause
- “but I’ll be back soon” — “but” is coordinating → joins to previous independent clause?

Wait — structure:

Main clause: “I left early”
Dependent clause: “so that I could get some work done” → modifies why he left early
Then: “but I’ll be back soon” — this is another independent clause joined by “but”

So we have:
- Independent clause 1: I left early
- Dependent clause: so that I could get some work done
- Independent clause 2: I’ll be back soon

Joined by: subordinating (“so that”) and coordinating (“but”) → meets definition of Compound-Complex

Sentence Type: Compound-Complex

7. Crossing the street is dangerous if you don't look both ways before you cross.

“Crossing the street is dangerous” — independent
“if you don’t look both ways” — dependent (subordinating “if”)
“before you cross” — also dependent? Wait — “before” is subordinating too.

But note: “if you don’t look both ways before you cross” — this whole thing is one dependent clause modifying “dangerous”. Inside it, “before you cross” is embedded — but still, overall, only one main independent clause.

So: one independent + one or more dependent → still Complex Sentence

Sentence Type: Complex

8. If you don't want to study, you should stay home, but you may regret it.

Breakdown:
- “If you don’t want to study” — dependent (subordinating “if”)
- “you should stay home” — independent
- “but you may regret it” — independent (joined by coordinating “but”)

So: one dependent + two independent → uses both subordinating and coordinating conjunctions → Compound-Complex

Sentence Type: Compound-Complex

9. Every time I go to mall, I spend all of my money on things that I don't need.

“Every time I go to mall” — “every time” acts like a subordinating conjunction → dependent clause
“I spend all of my money...” — independent
“that I don’t need” — relative clause (also dependent, introduced by “that”) — but it’s inside the object of the main clause.

Still, only one independent clause → rest are dependent → Complex Sentence

Sentence Type: Complex

10. Mom said that I can go to the museum with you but I have to be home early.

“Mom said” — independent
“that I can go to the museum with you” — dependent (introduced by “that” — subordinating)
“but I have to be home early” — independent? Wait — how is it connected?

Actually, the structure is:

Mom said [that I can go... but I have to be home early]

The “but” is inside the noun clause — so “that I can go... but I have to be home early” is one big dependent clause (object of “said”), containing two parts joined by “but”.

So overall: one independent clause (“Mom said”) + one complex dependent clause → still only one independent clause → Complex Sentence

Wait — but let’s think: Is “I have to be home early” really dependent? In this case, yes — because it’s part of what Mom said. The whole thing after “that” is a single noun clause, even though it contains a contrast with “but”.

So: only one independent clause → Complex

Sentence Type: Complex

11. Modern Warfare is a fun game but no game is better than Ms. Pac-Man.

Two independent clauses:
- “Modern Warfare is a fun game”
- “no game is better than Ms. Pac-Man”

Joined by coordinating conjunction “but” → Compound Sentence

Sentence Type: Compound

12. Todd and Nick are eating chips and salsa on a park bench before dinner.

Subject: Todd and Nick
Predicate: are eating chips and salsa on a park bench
“before dinner” — prepositional phrase, not a clause

Only one clause → Simple Sentence

Sentence Type: Simple
