ACT English: Semicolons Join Two Independent Clauses

A semicolon joins two independent clauses (complete thoughts) when there's no conjunction between them. Example: "The team played well; they won the game." Both "The team played well" and "they won the game" are independent. A semicolon connects them. Alternative: "The team played well, and they won the game" (using a comma and conjunction). Both are correct, but the semicolon is more concise. Rule: Use a semicolon only between two independent clauses; otherwise, use a comma or period.

Non-example (wrong): "The team played; winning the game." The second part "winning the game" is a phrase, not an independent clause. Fix: "The team played, winning the game" (comma instead).

Error 1: Using a semicolon before a dependent clause or phrase. Example (wrong): "She studied hard; to pass the test." The second part is not independent. Fix: "She studied hard to pass the test" (no semicolon). Error 2: Using a semicolon instead of a comma with a conjunction. Example (wrong): "She studied hard; and she passed." Correct: "She studied hard, and she passed" (comma, not semicolon, before "and"). Error 3: Overusing semicolons for style. Too many semicolons make writing choppy. Use them sparingly. Before you place a semicolon, check: Is the clause after it independent and complete?

This quick check prevents most semicolon errors on the test.

(1) "The sun rose; birds began to sing." (2) "The sun rose; beginning the day." (3) "He was tired; therefore, he rested." (4) "He was tired but rested anyway." (5) "I like writing; reading is enjoyable too." Identify which sentences use semicolons correctly. Answers: (1) correct (two independent clauses), (2) wrong (phrase, not clause; use comma instead), (3) correct (two independent clauses joined by semicolon and conjunctive adverb), (4) correct but no semicolon (comma with conjunction "but"), (5) correct (two independent clauses).

If you identified all five correctly, you understand semicolon rules. Redo any you missed until you see the pattern.

Semicolon questions appear on some ACT English tests. They test whether you understand independent clauses and punctuation hierarchy. Knowing when to use a semicolon vs. a comma or period gives you accurate answers on punctuation questions and adds reliable points.

Spend 15 minutes learning the rule and drilling the five sentences. By test day, you'll use semicolons correctly and confidently.
