Conjunctions are words that show the relationship between one idea and another idea. They also connect ideas.


I like apples, but I don't like apple juice.


Conjunctions --

  • join two sentences into one sentence.
  • follow specific punctuation rules. For example:
    • Use commas when a conjunction joins two simple sentences in a compound sentence, complex sentences, and time clauses.
    • Do not use commas when "because" introduces the second part of a complex sentence. For example: "Because I want to be healthy, I eat vegetables."
      BUT "I eat vegetables because I want to be healthy."
  • have a variety of uses. For example, they can:
    • show the time order of information
    • contrast information
    • add information
    • show cause and effect
  • are used in a sentence to link ideas within the sentence.
