Independent Clauses

An independent clause (also called a main clause) is a group of words that:

1. Has a subject (who/what does the action)
2. Has a finite verb (shows tense — not a participle or infinitive)
3. Expresses a complete thought — it can stand alone as a sentence

"She finished the project." ✓ (subject: She; verb: finished; complete thought) "Although she worked hard" ✗ (has subject + verb but NOT a complete thought — dependent)

Test: Remove the clause from the sentence — does it make sense alone?

"She laughed when she heard the joke."

• "She laughed." → Makes sense alone → independent clause ✓
• "when she heard the joke." → Doesn't make sense alone → dependent clause

Simple Sentence (One Independent Clause)

"The dog barked." "Mumbai is the financial capital of India."

Compound Sentence (Two or More Independent Clauses Joined by FANBOYS)

FANBOYS = coordinating conjunctions: For, And, Nor, But, Or, Yet, So

"She studied hard, and she passed the exam." "It rained heavily, but the match continued." "He didn't come, nor did he send a message."

Punctuation: Use a comma before the coordinating conjunction when joining two independent clauses.

✓ "I wanted to go, but I was tired." ❌ "I wanted to go but I was tired." (comma missing — acceptable in short sentences, but required in formal writing)

Complex Sentence (Independent + Dependent Clause)

"She passed the exam because she studied hard." (independent + adverb clause) "Although it rained, the match continued." (adverb clause + independent)

Compound-Complex Sentence

Contains two or more independent clauses AND at least one dependent clause:

"She studied hard because she wanted to win, and she did."

Common conjunctive adverbs: however, therefore, nevertheless, furthermore, consequently, moreover, thus

Run-On Sentence (Two IC joined without punctuation)

❌ "She studied hard she passed the exam." ✓ "She studied hard, and she passed the exam." OR "She studied hard; she passed the exam."

Comma Splice (Two IC joined with only a comma)

❌ "She studied hard, she passed the exam." ✓ "She studied hard; she passed the exam." OR "She studied hard, so she passed the exam."

Fragment (Dependent clause used as sentence)

❌ "Although she worked all night." ✓ "Although she worked all night, she couldn't finish on time."

Identify all independent clauses:

"The sun set behind the mountains, and the valley grew dark. Farmers returned home, exhausted after a long day. Although the harvest was good, many were still worried about the coming winter."

1. "The sun set behind the mountains" → IC
2. "the valley grew dark" → IC
3. "Farmers returned home" → IC
4. "many were still worried about the coming winter" → IC
5. "Although the harvest was good" → Dependent (doesn't stand alone)

1. Is this an IC? "When the bell rang." — Why or why not?
2. Identify the independent clause: "She cried because she was happy."
3. Fix the run-on: "He finished first he won the prize."
4. Fix the fragment: "Since nobody came to the meeting."
5. Stretch: Write a compound-complex sentence using "because" and "but." Label each clause.
