Fragments, Run-ons, and Comma Splices

SAT Reading & WritingStandard English ConventionsMedium

Diagnose the sentence-level error before choosing a repair.

What you need to know

  • A fragment is punctuated as a sentence but lacks an independent clause.
  • A run-on joins independent clauses with no legal boundary.
  • A comma splice joins independent clauses with only a comma.
  • The cleanest repair preserves the original logical relationship.

The AYLOTI method

  1. Mark every subject-verb pair.
  2. Divide the sentence into clauses.
  3. Classify each clause.
  4. Repair using subordination, coordination, or a legal strong boundary.

  2. Second unit begins with because and is dependent.
  3. Join the dependent reason to the independent clause.

Answer: “The archive expanded rapidly because volunteers scanned thousands of pages.”

Common SAT traps

  • Repairing a fragment with a semicolon.
  • Deleting a conjunction and creating a run-on.
  • Choosing punctuation based only on how long a pause sounds.
Quick check
