    Semicolons

    A semicolon is can be used in three different types of sentence structures.

    • To join two independent clauses.
      Example: Several environmental organizations recognized the treaty; few endorsed it.
    • To join two independent clauses when a conjunctive adverb is used.
      Example: Several environmental organizations recognized the treaty; however, few endorsed it.
    • To separate items in a list if the items in the list already necessitate a comma.
      Example: She has a son, Mike Nach, of Arizona; a daughter, Emily Rosa, of Colorado; and a sister, Sara Evans, of Minnesota

    Colons

    Colons are used to draw attention to certain words. They are used after an independent clause to direct attention to a list, appositive, or quotation. They are used between independent clauses when the second clause summarizes or emphasizes the first clause or after the greeting in a formal letter.

    • The sandwich requires several ingredients: bread, butter, cheese, ham, and tomatoes.
