SAT Reading & Writing: Semicolons Between Independent Clauses

39+ practice questions in Praczo

What you need to know

The concept, explained

  • 1

    A semicolon connects two complete, closely related independent clauses. It functions grammatically identically to a period.

  • 2

    If you can replace a semicolon with a period and both sides make sense as full sentences, the semicolon is used correctly.

  • 3

    You cannot use a semicolon with a coordinating conjunction (FANBOYS). "Sentence; and sentence" is incorrect.

  • 4

    You CAN use a semicolon with a conjunctive adverb (e.g., however, therefore, moreover), followed by a comma. "Sentence; therefore, sentence."

  • 5

    Never place a semicolon between an independent clause and a dependent clause/phrase.

Common mistakes
  • Using a semicolon because a pause "feels right" even though the second half is not a full sentence.
  • Using a semicolon and a comma interchangeably.
