SAT Reading & Writing: Sentence Combining

26+ practice questions in Praczo

What you need to know

The concept, explained

  • 1

    Sentence combining questions ask you to merge two sentences into one while maintaining the original meaning and observing grammatical rules.

  • 2

    The correct option is usually the most concise and direct, avoiding awkward or overly complex constructions.

  • 3

    Use commas with coordinating conjunctions (FANBOYS) or use subordinating conjunctions ("because," "although") to establish the correct logical relationship.

  • 4

    Avoid options that create run-on sentences, comma splices, or misplaced modifiers.

  • 5

    Turning one sentence into an appositive phrase (a noun phrase renaming another noun) is often the cleanest way to combine.

Common mistakes
  • Choosing a combined sentence that grammatically works but alters the original logical relationship between the ideas.
  • Selecting wordy versions that use passive voice or unnecessary repetition.
