ACT English Punctuation Semicolons and Colons Usage Rules

What This Is and Why It Matters for the ACT

Semicolons and Colons: Usage Rules is a crucial topic for the ACT English section, appearing frequently on every test. It's a challenging area, with many students struggling to understand the correct usage of these punctuation marks. This guide will help you master the rules and boost your ACT score.

Key Concepts (What You Must Know)

• Definition: A semicolon (;) is used to separate two independent clauses that are closely related in meaning. A colon (:) is used to introduce a list, a quotation, or an explanation.
• Grammar rule: Use a semicolon to join two independent clauses that are closely related, but use a comma and a conjunction (and, but, or) to join two independent clauses that are less closely related.
• Common vocabulary: Independent clause: a group of words that contains a subject and a verb.
• Important term: Parallel structure: using the same grammatical structure in a list of items.

Step-by-Step Strategy for This Topic

1. Read the sentence carefully: Identify the underlined portion and the punctuation marks used.
2. Determine the relationship between the clauses: Ask yourself if the two clauses are independent and closely related.
3. Eliminate incorrect options: Look for options that use a comma and a conjunction (and, but, or) instead of a semicolon.
4. Check your work: Verify that the correct punctuation mark is used to separate the two clauses.
5. Time management tip: Spend 1-2 minutes on each question, and focus on the most challenging ones first.
