Parallelism: The words and, but, nor, or, and yet are called coordinating conjunctions, which means that they join sentence elements that are grammatically alike. Their use commits the writer to creating structures that are parallel. Check your writing for these words and make sure that you have created the parallelism you need.

Examples of parallel structures with conjunctions in bold and the structures italicized:

    With independent clauses:

        Dona Maria acts as Cortes' translator during his conquest of New Spain, and he probably could not have
        succeeded in conquering the Aztecs without her help.

        Without Dona Maria's help Cortes could not have conquered Mexico, but he rarely gives her the credit
        that she deserves. [When joining independent clauses with a conjunction, use a comma before the conjunction.]

    With dependent clauses:

        Freud argues that the demands of civilization conflict with the demands of instinct and that this conflict is
        a major source of discontent.

        Cabeza de Vaca's journey demonstrates that one can adapt to other cultures without surrendering one's most
        basic values but that such adaptation will not be easy.

    With participial phrases:

        Looking at Spanish behavior through Indian eyes and considering forced conversion to be unchristian, Los
        Casas soundly condemns Spanish cruelty.

        Freud describes a divided ego, tempted by the id's desires yet constrained by the reality principle.

    With two adjectives:

        Constantly hungry and fearful of Indian reprisal if he refuses to cooperate, De Vaca has little choice but to
        embark on a career as a medicine man.

        Marlow can't decide whether the cannibals are savage or civilized.

    With prepositional phrases:

        The two goals of converting Indians and of acquiring wealth do not seem contradictory to Cortes.

        Occuring after the birth of modern science but before Darwinism, the argument from design that Cleanthes
        advances in Hume's Dialogues is typical of its time.
