    Boundaries (Punctuation and Sentence Structure)

    Commas, semicolons, colons, dashes, and proper sentence structure.

    What the SAT Tests

    Boundaries questions test punctuation that divides or joins clauses. You need to know exactly when to use a comma, a semicolon, a colon, and a dash — and when using any of them creates a comma splice or run-on.

    Key Tips for Boundaries (Punctuation and Sentence Structure)

    • Semicolons join two independent clauses — both sides must stand alone.
    • Colons introduce a list or an explanation, not a restart of the sentence.
    • Dashes can replace commas or colons for emphasis but must come in pairs if non-terminal.
