Cheat Sheet

  1. Meet the FANBOYS -

    FANBOYS stands for For, And, Nor, But, Or, Yet, So - a handy mnemonic that helps you recall the seven coordinating conjunctions (source: University of North Carolina's Writing Center). Think of FANBOYS as connectors that join words, phrases, or clauses of equal grammatical rank, making your sentences flow smoothly.

  2. Comma rules with independent clauses -

    When two independent clauses are joined by a FANBOYS conjunction, place a comma before the conjunction (e.g., "She planned to study, but she fell asleep"), as recommended by the Purdue OWL. This rule prevents run-on sentences and comma splices, boosting both clarity and style.

  3. No comma for compound predicates -

    If you're connecting two verbs or verb phrases that share the same subject, skip the comma (e.g., "He wrote and revised the report"), since there's only one independent clause (Cambridge Dictionary). This keeps your sentence tight and avoids unnecessary pauses.

  4. Using "neither…nor" for negatives -

    Pair "neither" and "nor" to link two negative ideas without a comma (e.g., "She neither laughed nor cried"), a pattern endorsed by Merriam-Webster. This structure is perfect for expressing balanced negation and adds a polished touch to your writing.

  5. Contrast vs. result: yet and so -

    "Yet" introduces a contrast (e.g., "It was raining, yet I went for a run"), while "so" shows a result (e.g., "I was tired, so I went to bed"), each requiring a comma when joining two independent clauses (Oxford Online Dictionary). Remembering "contrast yet result so" helps you pick the right conjunction every time.
