SAT Reading & Writing: Subordination and Coordination

36+ practice questions in Praczo

What you need to know

The concept, explained

  • 1

    Coordination joins two equal ideas using FANBOYS (For, And, Nor, But, Or, Yet, So) with a comma, or a semicolon.

  • 2

    Subordination joins unequal ideas, making one dependent on the other using subordinating conjunctions (Although, Because, Since, While, If).

  • 3

    Avoid double conjunctives. You cannot use both a subordinating AND a coordinating conjunction to join the same two clauses.

  • 4

    Incorrect: "Although it was raining, but we still played." (Use "Although" OR "but," not both).

  • 5

    The conjunction must create logically sound relationships. Use "because" for cause, "although/but" for contrast, etc.

Common mistakes
  • Selecting a choice with redundant conjunctions (double-jointed clauses).
  • Using a contrast word (however) when a cause/effect word (therefore) is needed by the logical context.
